The modern name given to a collection of ancient Egyptian mortuary texts made up of spells or magic formulas, placed in tombs and believed to protect and aid the deceased in the hereafter.

The collection, literally titled The Chapters of Coming-Forth-by-Day received its present name from Karl Richard Lepsius , German Egyptologist who published the first collection of the texts in It was probably compiled and re-edited during the 16th century BC , and over half of the collection is comprised of the Coffin Texts dating from c BC and the Pyramid Texts dating from c BC. The Book of the Dead had numerous authors, compilers, and sources.

Scribes copied the texts on rolls of papyrus, often with illustrations, and sold them to individuals for use in burials.

Many copies of the book have been found in Egyptian tombs, but none contains all of the approximately chapters. The choice of spells varies from copy to copy. A climatic subdivision of the Holocene epoch, following the Pre-Boreal and preceding the Atlantic climatic intervals. Radiocarbon dating shows the period beginning about 9, years ago and ending about 7, years ago. The Boreal was supposed to be warm and dry. In Europe, the Early Boreal was characterized by hazel-pine forest assemblages and lowering sea levels.

In the Late Boreal, hazel-oak forest assemblages were dominant, but the seas were rising. In some areas, notably the North York moors, southern Pennines and lowland heaths, Mesolithic man appears to have been responsible for temporary clearances by fire and initiated the growth of moor and heath vegetation. A rounded stone of various sizes with a bored hole in the middle, found in central and southern Africa and dating back 40, years.

Some were used as weights on digging sticks. Joined to mainland Southeast Asia during the low sea-level Pleistocene period archaeological sequences have been found in the Niah Caves of Sarawak and the Madai-Tingkayu region of Sabah. The Niah Great Cave sequence suggests the presence of a population of early Australoids from about 40 years ago and evidence from all sites indicate that the ancestors of present-day Borneans arrived around BC possibly from the Philippines. Though traces of Homo erectus from 2 million years ago were found on neighboring Java so far no evidence has been found of Homo erectus in Borneo.

Roman trade beads and Indo-Javanese artifacts give evidence of a flourishing civilization dating to the 2nd or 3rd century BC. A Sanskrit inscription dated to c AD is the earliest historical document on the island. Three rough foundation stones with an inscription recording a gift to a Brahman priest date from the early 5th century AD found at Kutai provide evidence of a Hindu kingdom.

The first recorded European visitor was Franciscan friar Odoric of Pordenone who visited on his way from India to China in The site of two villas that were suburbs of Rome, near Pompeii, with important and sumptuous artifacts and painted rooms dating c 40 BC. These include possessions of the great patrician families of Rome, such as paintings illustrating Dionysiac mysteries, jewels, and magnificent gold and silver household furnishings.

The cubiculum of one villa at Boscoreale is preserved in the Metropolitan Museum of New York City and other items are kept at the Louvre. Many of the rich hoards were accidentally saved by the volcanic catastrophe of 79 AD.

A cave site near Abetifi, Ghana, which yielded one of the first scientifically excavated assemblages of a West African Neolithic industry. Radiocarbon dating has shown that occupation began around the middle 4th millennium BC and continued for at least years.

Throughout the sequence, a microlithic chipped-stone industry was associated with simple pottery and with ground-stone ax - or hoe-like implements. The site of prehistoric ritual monuments and Neolithic passage graves in the valley of the River Boyne, Ireland, dating to the 4th millennium BC. The complex includes five henges, a number of mounds, and the three great passage graves of Newgrange, Dowth, and Knowth. These megalithic tombs are set in round mounds and usually set on hilltops or grouped in cemeteries.

These structures are notable for their size, their decoration, and the architectural expertise involved. Its characteristics are highly decorated Carrowkeel style of pottery, bone pins with poppy- or mushroom-shaped heads, pendants, and beads. A settlement site and cemetery dating from at least the 2nd millennium BC in southern India. Wheeler found a Chalcolithic level c BC with abundant microliths, polished stone axes, and crude burnished gray pottery, an Iron Age level 1st millennium BC with black-and-red ware, tombs, stone circles, and ossuaries for bones, and a level from the 1st century AD with rouletted ware and traces of Roman contact.

Bone points and some evidence of a stone-blade industry have also been found. There are many cattle bones, but also sheep and goats. The culture seemed to continue with little change for many centuries. An important building material of individual blocks of clay or mud, some with tempering of sand or straw.

Bricks, which are not always rectangular, may be baked in a kiln to terra cotta or sun-dried -- which is referred to as mud-brick or adobe. The chief building material throughout the Near East has always been mud-brick. Bricks can be used as dating criteria, especially when they bear stamped inscriptions. Decorative glazed bricks first appeared in Assyrian times, as at Ishtar Gate in Babylon.

A small pine tree, approximately feet m high, which is the oldest living tree in the world. It is native to the Rocky Mountains of the United States, at elevations above 7, feet 2, m , and they have the longest life-span of any conifer.

A stand of this tree in eastern Nevada is known to have several trees over 3, years old, and one of them is thought to be about 4, years old. The combination of these and some well-preserved dead examples have allowed a dendrochronological key to be built, has changed some of the assumptions underlying radiocarbon dating , and has provided calibration for radiocarbon dates going back about 7, years.

A cave and mine site in central Zambia in which a complete skull was found which is attributed to Rhodesian Man Homo sapiens rhodesiensis and has characteristics similar to Neanderthals.

The skull was found on a ledge in , and has no definite evidence for a date, but the artifacts in the Bone Cave were of the Middle Stone Age Charaman industry. Dating by amino-acid racemization indicates an age of more than , years. Mining operations have exposed a long series of stone industries extending from the Acheulian to the Charman. Over 25 percent of the species represented by the associated faunal remains are now extinct. French mineralogist, geologist, and naturalist, who first arranged the geologic formations of the Tertiary Period from Brongniart helped introduce the principle of geologic dating by the identification of distinctive fossils found in each geological stratum.

Deep pit dwellings are associated with ground stone axes, bone tools, and coarse gray burnished pottery. These characteristics plus the absence of blades, use of pierced rectangular knives, and association of dog skeletons with human burials, all seem to point to connections with central and northern Asia, as Mongolia, rather than with the rest of the Indian subcontinent.

Hunting seems to have been the main basis of the economy. Seven sites in eastern Sudan, dating to BP, with ceramics and stone artifacts. The cultural group belonged to the Kassala phase.

An ancient seaport on the Mediterranean coast just north of Beirut, Lebanon and one of the oldest continuously inhabited towns in the world. Papyrus received its early Greek name byblos, byblinos from its being exported to the Aegean through Byblos.

The English word Bible is derived from byblos as the papyrus book. Byblos was the main harbor for exporting cedar and other valuable wood to Egypt from BC on.

Egyptian monuments and inscriptions on the site describe to close relations with the Nile valley throughout the second half of the 2nd millennium. Byblos has yielded almost all of the known early Phoenician inscriptions most of them dating from the 10th century BC. The crusaders captured the town in but they later lost it to the Ayyubids in The ruins today consist of the crusader ramparts and gate; a Roman colonnade and small theater; Phoenician ramparts three major temples and a necropolis.

A site in Jutland, Denmark, with copper finds dating to c BC , among the earliest metal objects in Denmark. Archaeological complex dating from BC in the Ayacucho valley of Peru.

It showed the first evidence of an economic system in which products of lower-elevation villages and camps corn, beans, squash, gourd, chile, coca were exchanged for potatoes, quinoa, and camelids of the seasonally nomadic herders of the higher elevations.

A town and archaeological site in Wales in which the Romans established a legionary fortress dating to AD when the conquest of the Silures of Wales began. The foundation of the fortress is set on a terrace along the Usk and it is one of three major legionary fortresses -- the other two being at Chester and York. Originally built of timber and earth, it had been largely rebuilt in stone before the Roman garrison left during the abandonment of the province. Evidence has been found for centurion houses, workshops, barracks, stores, ovens, hospital, baths, and latrines.

There is also an amphitheater, two bath buildings, and extensive cemeteries in an associated settlement. The fortress was occupied, probably by a nonmilitary population, until the s. Caerleon, traditionally a seat of the legendary King Arthur, was a Welsh princely capital until the Norman Conquest This side notched , triangular arrow point has straight sides to slightly concave basal edges. A few may have slightly convex basal edges. In a addition to the side notches on the blade, usually just above the primary side notches, or it may be serrated.

Points with two or three notches are the most common. The Cahokia point was named by Edward G. Clair and Madison counties in Illinois.

An early Mississippian point dating in the A. The capital of modern Egypt, which has more than registered historical monuments -- the largest number of any African or Middle Eastern city -- dating from AD.

The ancient metropolis has stood for more than 1, years on the same site. The Pyramids of Giza stand at the southwestern edge of the Cairo metropolis. Other treasures include reliefs, sarcophaguses, papyri, funerary art and the contents of various tombs, jewelry, ornaments of all kinds, and other objects. A cyclical system of measuring the passage of time. The day is the fundamental unit of computation in any calendar.

Most ancient civilizations and perhaps some non-literate prehistoric societies developed calendrical systems to mark the passage of time and various methods have been employed by different peoples. Where these were both carefully calculated and written down, as in Egypt, Mesopotamia and Mesoamerica, they are of considerable assistance to archaeologists for dating purposes. The Long Count system was in use by c 1st century BC if not before.

Ancient Near Eastern calendars varied from city to city and from period to period. In most cities the year started in the spring and was divided into 12 or 13 months. In some places the months were of fixed length; in others they were lunar months starting at the first sighting of the crescent of the new moon. As there are more than 12 lunar months in a solar year additional, or intercalary, months were included so that every third year contained 13 months. The earliest Egyptian calendars were based on lunar observations combined with the annual cycle of the Nile inundation, measured with nilometers.

On this basis, the Egyptians divided the year into 12 months and three seasons: The Egyptians had day months and 5 intercalary days in their solar or civil calendar. For agricultural purposes and for determining religious festivals, they used a different calendar based on observations of Sirius, the dog star.

The calendar in use in ancient Mesopotamia and the Levant was lunar, based on 12 months of 30 days each. This type of calendar is still used in both Judaism and Islam for religious purposes, though many countries now also employ the Gregorian solar calendar for secular purposes.

The origin of the calendric system in general use today -- the Gregorian calendar -- can be traced back to the Roman republican calendar, which is thought to have been introduced by the fifth king of Rome, Tarquinius Priscus BC. This calendar was likely derived from an earlier Roman calendar -- a lunar system of 10 months -- that was supposedly devised about BC by Romulus, the founder of Rome.

He then adapted the Egyptian solar calendar for Roman use, inserting extra days in the shorter months to bring the total up to , with the addition of a single day between the 23rd and 24th February in leap years. This calendar, known as the Julian Calendar, remained in use until the time of Gregory XIII in , who made a further correction of eleven days and instituted the calendar which is in general use today.

Very useful to Mesoamerican archaeologists is the Maya Long Count or Initial Series, which was a means of recording absolute time. Its starting date of BC using the Goodman-Thompson-Martinex correlation marks some mythical event in Maya history and itself stands at the beginning of a cycle 13 Baktuns long.

A Baktun at , days in the largest unit of time in the calendar and is further divided into smaller units: Thus Long Count dates are expressed in terms of these units in a five place notation. Therefore the date 9. In cultural contexts, however, the dates are inscribed as a series of hieroglyphs which incorporate numeration via bars units of five and dots units of one.

It is less precise, however. An absolute dating technique used when an object has been inscribed with a date from an ancient calendrical system or is associated with calendrical inscriptions that can be correlated with a modern calendar. A method used to obtain the most accurate dating, especially with radiocarbon dating. The term refers to the adjustment of dates in radiocarbon years by means of the dendrochronological data so that a date in calendar years is achieved.

Fluctuations in the amount of carbon 14 in the atmosphere mean that radiocarbon dating is not completely accurate. By obtaining radiocarbon dates for wood of known dendrochronological date, a correction factor can be introduced to calibrate radiocarbon dates.

Uncalibrated dates are raw dates in radiocarbon years. Accurate calibration of radiocarbon dates are not possible before BC.

An assemblage of artifacts including choppers, scrapers, leaf points, and other tools from the surface of the high terraces in Rio Pedregal, Venezuela. Dating indicates the site may have been inhabited 15, years ago. Neolithic peoples inhabited present-day Cambodia during the 2nd and 1st millennia BC. Stone tools have been found in terraces of the Mekong River in possible association with tektites from a shower that fell c , to , years ago.

A major Neolithic mound site at Somrong Sen yielded elaborate assemblage which seems to predate BC. Khmer civilization developed over several distinct periods, starting with the Hindu-Buddhist kingdoms of Funan and Chenla in the 1st century AD, which extended into the 8th century.

The site of a national monument on the coast of the Chukchi Sea with a horizontal stratigraphy covering the whole of north Alaskan prehistory. The stratigraphy is visible as a sequence of strips, roughly parallel to the shoreline, with the oldest, Denbigh, being furthest from the present-day shoreline.

This horizontal sequence, in combination with the vertical stratigraphy of Onion Portage , forms the most reliable chronological framework in Western Arctic prehistory.

Its known rate of decay is the basis of radiocarbon dating. Willard Libby discovered natural carbon Libby showed the essential uniformity of carbon in living material and went on to measure the radiocarbon level in organic samples dated historically -- materials as old as 5, years from sources such as Egyptian tombs. His work made this dating method available to scientists. Its inner rampart was built in AD. The site is one of the best-preserved examples of a medieval fortified town in Europe with an inner wall and citadel dating from 11thth centuries.

The site was extensively restored in the 19th century and the church of Saint-Vincent and the cathedral of Saint-Michel, both 13th century, survive. Roughly spherical or slightly lobate artificially shaped carved stones dating to the later Neolithic and found only in Scotland. Unornamented stone balls are, however, found in other areas of the British Isles in 4th and 3rd millennia BC contexts.

Caso found evidence of five major phases, dating back to the 8th century BC , and established a rough chronology through comparisons with other sites. Caso also deciphered the Mixtec Codices. He made important contributions to regional archaeology and to the interpretation of Mixtec manuscripts, Mexican calendars, and dynastic history in general. He held posts as head of the Department of Archaeology at the National Museum, director of the museum, and director of the National Institute for Indian Affairs.

An Upper Palaeolithic rock shelter at Castelmerle, southwest France. There were two Aurignacian levels with art objects of carved or painted stone. The art from Castanet and neighboring Blanchard rock shelter is amongst the earliest known, dating c 33, BC. A tell site in western Bulgaria of the first temperate Neolithic, dating to c BC.

There are Kremikovci occupation levels and one Karanovo level. The farming economy grew emmer wheat and barley and raised cattle. Kremikovci painted wares include a rich polychrome assemblage dating to the end of the Early Neolithic.

It is located close to the Makapansgat site, the oldest cave site known in Africa. Both offer extremely early evidence of the use of fire by man in Africa and tools of the transitional Acheulian-Fauresmith type. The earliest deposits of the Cave of Hearths are Acheulian, followed by a long period of abandonment. There was a long succession of Pietersburg industries and some signs of typological continuity between the Acheulian and the Pietersburg assemblages.

The Pietersburg industry was succeeded by an assemblage of subtriangular points and flake scrapers similar to the Bambata industry of Zimbabwe. A site on a tributary of the Tigris River in eastern Turkey with occupation dating from c BC. There are impressive architectural remains with stone foundations and evidence of a farming and hunting community. The latest phase included domesticated sheep and goats.

Einkorn wheat was cultivated as well as emmer wheat, peas, and lentils. Another important feature of this site was the very early appearance of simple copper objects, derived from closeby Ergani Maden.

Also, clay bricks, baked figurines, and pottery have been found. A type of Chinese pottery with a pale green glaze -- either porcelain or stoneware.

Over inhumations are known, occurring in groups, some with rich grave goods of the Hamangia culture. The latter had short-lived occupation sites and is associated with the Ezero group. These carvings are in a style unlike anything else reported in Peru, executed by deep-line incisions of warriors and dignitaries in regalia on dressed and carved stone slabs. Most of the figures represent humans. The site has one of the earliest appearances of monumental art in Mesoamerica.

Descendant of earlier painted pottery Neolithic cultures, it is characterized by the use of amphora-like jars with loop handles, comblike designs, and by copper tools axes and rectangular knives.

The culture survived into historic times and remains from as late as the 1st century BC have been found. It also refers to the Spring and Autumn [Annals]" the first Chinese chronological history said to be the traditional history of Lu as revised by Confucius. It is one of the Five Classics of Confucianism. The name which is actually an abbreviation of "Spring Summer Autumn Winter derives from the custom of dating events by season as well as by year. The work is a complete account of significant events that occurred during the reign of 12 rulers of Lu, the native state of Confucius.

It is interpreted by Confucian scholars in their commentaries. The settlement was surrounded by stone defenses with six semi-circular bastions; inside were a number of small rooms, separated by narrow paths. The cemetery of around tombs, each containing one or two bodies, had artifacts of the so-called Keros-Syros culture, including the highly decorated dishes known as frying pans. Converted to charcoal or carbon usually by heat, organic materials may be preserved.

Partial burning reduces the materials to a carbon-rich residue. In the case of wood, this residue is charcoal. Many organic materials may not retain their structure and become an amorphous residue. Charred remains are preserved on archaeological sites because carbon is relatively inert in the soil and the microorganisms which would normally break down organic material are unable to make use of this form of carbon. Charred remains are a particularly good material for radiocarbon dating.

A site in Somerset county, England, where a gorge and caverns have offered up human remains and artifacts stone and bone tools dating back to the Stone Age. Cheddar cheese was first made there at or before the beginning of the 12th century and was aged in the caves. Early examples are found in the early Bronze Age of the Carpathian Basin dating to the mid 2nd millennium BC ; they appear soon afterwards in northern and western Europe, although generally less heavily decorated than their southern counterparts.

An interstadial of the Devensian cold stage the last glaciation , of c 61, bp according to radiocarbon dating -- though it could be older.

A site on the Grijalva River in Chiapas, Mexico, with one of the longest occupational sequences in Mesoamerica, c BC to the present. It flourished in Late Pre-Classic to Early Classic times with adobe construction, ceramics and figurines, and then pyramids dating to BC and residential complexes of cut stone to BC.

The style and iconography of certain artifacts indicate contact with Izapa and Kaminaijuyu in the Late Pre-Classic. Hundreds of broken sherds tell of trade contact with sites in the Penen, Monte Alban, and Teotihuacan in the Early Classic.

It was characterized by architectural and ceramic traits which convey the rise of the Classic Maya civilization: Their sites are quite uniform and there was a variety of ceramic forms. Chicanel pottery includes dishes with wide, grooved rims, bowls, and vessels resembling ice buckets. The El Mirador construction dwarfs even that of Tikal, although El Mirador only flourished through the Chicanel phase.

The sites have evidence of metallurgy and manufacture of pottery. A site in the coastal valley south of modern Lima, Peru, where excavations have revealed settlements dating to the Pre-Ceramic period c BC. The Chilca Monument was originally a summer camp and later, due to an increasingly warm climate, became favorable for a subsistence pattern called encanto.

There are remains of conical huts of cane thatched with sedge. The dead were buried wrapped in twined-sedge mats and the skins of the guanaco.

The lomas, patches of vegetation outside the valleys that were watered at that season by fogs, began to dry up. The lomas had provided wild seeds, tubers, and large snails; and deer, guanaco, owls, and foxes were hunted. The camps were eventually abandoned c BC in favor of permanent fishing villages. Dolichocephalic human remains date to this period but appear ultimately to have been replaced by brachycephalic types some time after BC.

South American Indians who created the largest and most important political system in Peru before the Inca, and who developed large-scale irrigation systems. The black pottery had molded reliefs with some vessels in the shape of people, animals, houses, and everyday items. The stirrup-spout and spout-and-bridge vessels are the most common forms. There were also objects of silver and gold. Chanchan was capital, a vast settlement of giant rectangular enclosures. In , however, they were conquered by the Inca, who absorbed much of the culture, including their political organization, irrigation systems, and road engineering.

A site on the coast of northern Chile where the earliest intentionally mummified humans have been found, dating to c bp.

The bodies were disemboweled, skinned, covered with clay, and clay masks were placed on the faces. A small teardrop-shaped bifacial point found in central Alaska and dating to c 12,, bp; they are diagnostic of the Nenana complex. Late Chiripa pottery of the Early Horizon Period BC is decorated with cream on red color zones, separated by incised lines. Early pottery is a cream-on-white ware, decorated with geometric designs. The common form is a flat-bottomed, vertical-sided open bowl.

The artistic style is linked to Pucara and Tiahuanaco. There is a series of rectangular rooms, some with underfloor stone-lined graves, arranged around a rectangular plaza.

An unusual feature is the storage space between the double walls of some structures. Excavations revealed a lithic flake industry as early as the Late Pleistocene, dating between 9, to 11, years ago. Wood fragments helped define a Chivateros I period of c BC. There is also a red zone with some flint chips which, by comparison of artifacts of the nearby Oquendo workshop date to pre, BC.

The whole industry is characterized by burins and bifaces with the upper-level Chinateros II containing long, keeled, leaf-shaped projectile points which resemble points from both Lauricocha II and El Jobo.

Dating has been aided by the deposition of both loess and salt crust layers which suggest alternating dryness and humidity and which can be synchronized with glacial activity in the Northern Hemisphere. An ancient Elamite site located near Susa in southwestern Iran. It is especially known for its remains dating to the Middle Elamite Period c BC , when the Elamite ruler Untash-Gal built a magnificent ziggurat, temples, and a palace.

The remains of the ziggurat, the largest one known, are feet m square and 80 feet 24 m high, less than half its estimated original height. Other palaces, a reservoir, and the fortification walls have been excavated of the city, which was lavishly laid out but never completed.

There are also a variety of small artifacts, including an excellent collection of Middle Elamite cylinder seals, and evidence of glass and glazes. The type site is at Kotsebue Sound. Cape Krusentern, Point Barrow, and Onion Portage are other Arctic sites with the characteristic coarse stamped pottery.

Tool assemblages are diverse with some of polished slate. Oil lamps first appear in Choris times. Any method used to order time and to place events in the sequence in which they occurred. A sequential ordering that places cultural entities in temporal, and often spatial, distribution. It involves the collection of dates or successive datings establishing the position in time of a series of phenomena such as the phases of a civilization or the events of the history of a state.

For periods or areas for which no textual evidence is available, relative chronologies have to be established and these are mostly based on pottery sequences and typology. Relative chronology is also based on the application of the principles of stratigraphy and cross-dating. The discovery of inscribed monuments and calendars associated with dated astronomical observations contributed to the development of an Egyptian chronology and it has served as a framework -- through cross-dating -- for all other Near Eastern chronologies.

Inscribed Egyptian objects found in Near Eastern contexts have allowed the latter to be dated. Absolute chronology is based on scientific methods such as radiocarbon dating , thermoluminescence dating, and archaeomagnetism.

Dates are often calibrated with dendrochronological dates. For dates after BC , an absolute chronology is not likely to change by more than ten years.

Four main occupation phases have been found, all of which are defined by rich painted ware assemblages. Level I has some of the earliest white-on-red painted pottery of the First Temperate Neolithic and the latest level has polychrome painted pottery of Starcevo-Cris. An early Neolithic millet-cultivating site in China.

Features include pithouses, storage pits, and burials with artifacts including querns, ground-stone sickles, tripod vessels, and bone and stone fishing and hunting implements.

Animal domestication is also attested to the site, dating to the early 6th millennium BC. An early flake-tool culture of Europe, dating from the early Mindel-Riss Great Interglacial of the Pleistocene epoch, which occurred from 1,, to 10, years ago. It was named after discoveries at Clacton-on-Sea, Essex, England.

A kind of concave scraper, perhaps used to smooth and shape wooden spears, is typical of the Clactonian industry. Apart from the tip of a wooden spear, the artifacts consisted of trimmed flint flakes and chipped pebbles, some of which can be classified as chopper tools. The Clactonian seems therefore to have coexisted with Early Acheulian. Some believe that the two industries are quite distinct, while others maintain that both assemblages might have been made by the same people, and that the Clactonian could in theory be an Acheulian industry from which handaxes were absent because such tools were not needed for the jobs carried out at a particular site.

Clactonian and related industries are distributed throughout the north European plain, and Clactonian tools are similar in appearance to those produced in the Soan industry of Pakistan and in several sites in eastern and southern Africa.

The Tayacian industry of France and Israel is believed to be a smaller edition of the Clactonian. In form they are similar to free-standing conical beakers, but they are embellished by a series of unusual clawlike protrusions.

In many cases the glass is tinted brown, blue, or yellow. The beakers were probably made in Cologne or Trier, Germany. A limestone cave in northeastern Victoria, Australia, with human occupation deposits dating from c 16, BC. Ochre and hearths as well as stone tools of the Australian Core Tool and Scraper Tradition have been found and the tools resemble similar Tasmanian artifacts.

Bones of extinct animals found in deposits which are more than 20, years old and are separate from the human deposits. Australian Small Tool Tradition artifacts were excavated from late Holocene deposits in a rock shelter outside the main cave.

A piece of metal or, rarely, of some other material such as leather or porcelain certified by a mark or marks upon it as being of a specific value. Coinage is considered to be any standardized series of metal tokens, their specific weights representing specific values, and usually stamped with designs and inscriptions.

Coins or coinlike objects were first issued by the Lydians of Anatolia in the late 7th century BC , made of the gold-silver alloy electrum. Their use was then adopted in the Far East, then around the Mediterranean, and has since spread throughout the world. Early coins were used for specialized, prestigious purposes and not for everyday exchange.

The early Greek coins were also made of electrum, silver, or gold; the first Roman coins were produced in the early 3rd century BC and were also made of precious metals. Later in that century the first bronze coin was introduced. These material remains are self-dating, though they do not always date" the materials they are found with as they may have been traded handed down through generations or displaced in the stratigraphy of a site.

It became the capital of the province of Lower Germania, which was an important commercial center. In , Constantine the Great built a castle and a permanent bridge to it across the Rhine. About it was conquered by the Franks, and it soon became the residence of the kings of the Ripuarian part of the Frankish kingdom.

Ceramics and glass were manufactured in Cologne in Roman times. Traces of the Roman period survive including the principal elements of the street plan, town walls and gates, Roman and Gallo-Roman temples, water installations, Rhine port, bridges and fort, pottery and glass factories, and villas and cemeteries. In the 5th century, the Roman town was overrun by the Franks.

During the Frankish and Carolingian periods and much of the Middle Ages, Cologne was a major bishopric and a leading commercial and cultural center. Spectacular Frankish royal graves dating to the mid-6th century have been uncovered. British antiquary who established the techniques of archaeological excavation in Britain. He excavated a large number of barrows mostly on Salisbury Plain , classified and published his findings. He also recorded many other monuments of the area.

However, at the time there was no means of dating the material he found. A rock shelter site on the Dordogne River in southwest France, near the town of Domme. There are 64 archaeological levels, including nine bottom levels of the Acheulian industry dating from the end of the Riss glaciation , followed by a series of 55 Mousterian levels.

Occupation ended just before the end of the Mousterian period, and there is a radiocarbon date of just over 37, BC from Level 12, near the top of the deposit. The site has the largest number of cultural levels of any Palaeolithic site known to date. The 55 Mousterian levels have formed the basis for the analysis of the Mousterian into five main types.

A burial pit has been recognized in the Mousterian levels with some human bones. The site has fauna and pollen evidence from all levels. A Copper Age site on the plain around Palermo, northwest Sicily, where a number of rock-cut shaft-and-chamber tombs a forno or oven-shaped type have been found dating to the 3rd millennium BC.

They were used for collective burial and the associated grave goods include pottery vessels and some metal tools and weapons. Materials that are not part of a natural archaeological deposit or assemblage but which have intruded or altered the deposit or assemblage. The term is often applied to samples taken for radiocarbon dating which have been affected by their environment, for example by humus, which also contains carbon, and may be much younger than the sample, thus resulting in an inaccurate age determination.

Remains of military quarters, granaries, and temples may still be seen. An ancient city of Greece, located where the Peloponnese meets the isthmus that connects it to the Greek mainland. The city has an exceptionally high acropolis on Acronocorinth Hill and profited from having ports on both the Corinthian and Saronic Gulfs. The site was occupied from before BC , but its history is obscure until the early 8th century BC , when the city-state of Corinth began to develop as a commercial center.

There is evidence of a Neolithic and an Early Bronze Age settlement at Corinth, both of considerable size. There is little evidence of Mycenaean settlement, however, and the next major settlement belonged to the Dark Age, c late 10th century BC.

Corinth was a very important city throughout the Archaic, Classical, and Hellenistic periods. The Corinthians established colonies at Corcyra and Syracuse, later making them dominant in trade with the western Mediterranean.

From c BC , Corinthian painted vases in the black-figure technique which the Corinthians invented were exported all over the Greek world. Corinthian pottery provides the most useful dating method available to archaeologists studying this period. Northwest of the agora stand seven Doric columns, which are the remains of the Temple of Apollo c BC.

Callimachus is said to have invented the Corinthian column capital here c BC. Many of the visible remains date from the classical Greek and especially the early Roman periods, including a Roman agora marketplace , the Odeon, the Pirene fountain, the Glauke fountain, temples, villas, baths, pottery factory, gymnasium, basilica, theater, and an amphitheater. Parts of the classical fortifications on the acropolis survive.

In the later medieval period it then passed from Frankish to Venetian and eventually to Turkish hands. Substantial buildings from all these periods have been found in excavations since Modern Corinth was founded in , 3 miles north of the ancient town, after an earthquake leveled the latter. Type of middle Bronze Age pottery vessels found in the extreme southwest of Britain and dating to the 2nd millennium BC.

Generally rather barrel-shaped in profile and often with a highly decorated upper body, these large vessels commonly have strap handles. The decoration includes herringbone and lattice patterns, in the main executed in twisted cord and impressed techniques.

Related to Trevisker ware in southwestern England. The use of various methods, often multiple methods, to demonstrate the equivalency of stratigraphic units. This term refers to the relation of one stratigraphical unit to another, by petrological, osteological, lithographic, cultural, chronological, or palaeontological means. For example, stratigraphic units may be correlated using palaeontological criteria, absolute dating methods, relative dating methods, cross-dating methods, and position relative to the glacial-interglacial cycle by examining physical and biological attributes.

Correlation of fossil inclusions is a principle of stratigraphy: A type of medieval pottery flask, of which the majority were made of leather and have not survived. Merovingian and Carolingian pottery costrels tend to be roughly round in shape, with a slight neck for a stopper. The sites were small, short-lived settlements suggesting agriculture and fishing as well as movement for seasonal reasons.

Most burial sites used inhumation rites, although cremation is found. Cotofeni sites have a rich pottery assemblage with handled mugs and pitchers with lentil- impressed decoration. A population of anatomically modern Homo sapiens dating from the Upper Paleolithic Period c 35,, years ago , first found in in a shallow cave at Cro-Magnon in the Dordogne region of southern France.

French geologist Louis Lartet uncovered five archaeological layers and the race of prehistoric humans revealed by this find was called Cro-Magnon and has since been considered, along with Neanderthals, to be representative of prehistoric humans at that time. It was also the first discovery of remains of Homo sapiens in a deposit containing Upper Palaeolithic tools. The skeletons had been carefully buried, covered with red ochre, and necklaces laid beside them.

They were the earliest known modern humans in Europe, who were characterized by a long skull and high forehead, a tall erect stature, and the use of blade technology and bone tools. They were associated with the Aurignacian culture, which produced the earliest European art.

Unlike Neanderthal man , the remains are hardly different from modern man. A river valley in western Africa, mostly in southeastern Nigeria, where more than huge anthropomorphic monoliths were found, probably dating from 16th century AD.

A type of bronze dress fastener characterized by a simple shaft with a short cross-piece set in the form of a T. Some examples have decoration on the upper part of the shank and head. The type site of the Cucuteni is in the Siret valley of Romania and the type site of the Tripolye is near Kiev in Ukraine.

The Cucuteni is divided into stages: The late Cucuteni-Tripolye phase is regarded as the local climax of Neolithic cultural development. They produced fine wares red or orange and was decorated with curvilinear designs painted or grooved on the surface on a large scale and long chipped stone blades. They also mastered metallurgical techniques such as alloying, casting, and welding. There was a subsistence economy depending on fruits and the earliest recorded domestication in Europe of the horse.

The villages consisted of long, rectangular houses, though the Tripolye people practiced shifting agriculture and frequently moved. In anthropology, the transmission or borrowing of certain culture traits from the group of origin into a foreign group; usually technological elements rather than those of social organization. This term defines the spread of ideas, traits, or people from one area to another -- not necessarily implying the movement of people, since trade and the adoption of new ideas from neighboring cultures are reasonable explanations of diffusion.

The diffusion of new ideas can come, however, from the peaceful or warlike expansion of a population into new territory. The theory of diffusion was used in the past to explain the beginning of most new ideas: It is now clear, through the use of new dating techniques, that independent invention was certainly possible and probable for many new ideas.

A rock shelter in southern Corsica, France, with a sequence of deposits from Mesolithic and Neolithic occupation levels dating to the 7th millennium BC -- the earliest evidence of man in Corsica. The Early Neolithic levels 6th millennium BC had pottery with punctated and incised decoration , and a lithic industry with geometric trapezes on hard rock and obsidian imported from Sardinia. This was the standard seal form of the Mesopotamian civilization, starting in the Uruk period.

The incised stone cylinder was rolled over a soft surface so that the design appeared in relief. These seals were used to mark property and to legalize documents. A kingdom founded by Fergus and his brothers when they led the Scots from Ireland to the northeast coast of Scotland in the 5th century AD, roughly the modern county of Argyll Argyllshire. It was ruled from the rock fortress of Dunadd, a nucleated fortified citadel dating to around It consists of a dry-stone central stronghold with two outer walled enclosures.

In about , Kenneth MacAlpin extended his rule over the Picts to lay the foundations of the kingdom of Scotland. Columba and for the island of Iona which was a base for the conversion of northern Britain to Christianity. An early blade-and-burin industry of Cyrenaica, Libya, dating to 40,, years ago.

It is thought to be the oldest dated blade-and-burin industry of Upper Palaeolithic type and is recorded from only two sites: Hagfed ed-Dabba and the Haua Fteah. The Dabban is clearly related in some way to the broadly contemporary Upper Palaeolithic complex of Europe and the Near East with backed blades, burins, and endscrapers being its most characteristic artifacts.

Its origins are still unknown. Dabban occupation of Haua Fteah continued until c12, BC. The defenses were built with a timber-laced rampart, remodeled twice, and the main gateway is just as old. Within the ramparts, there was a permanent settlement.

By the 4th century, rows of 4- and 6-post structures, flanked the roads, but were later replaced by circular houses. The site was abandoned c BC. The site consists of large numbers of pits and post holes, whose associated material has been subdivided typologically into five phases.

There are two associated pottery styles, painted in black and broad red bands on buff ware, and incised on dark burnished ware, belong in the Middle Neolithic. There was also a long blade and tanged point stone industry closely related to fishing. They depict nude male figures, some with mutilated or elaborately emphasized sexual organs, in unnatural dancing or possible swimming poses.

Certain elements of the iconography, such as thick lips and downturned mouths, indicate an Olmec origin. Associated hieroglyphs and calendar dates support this theory. The term means "dancer" in Spanish. Swedish geologist, originator of the varve-counting method used in geochronology, first published in a paper entitled, A Geochronology of the last 12 years".

De Geer observed that lake beds consist of couplets of laminated sediments varves light-colored silt layers alternating with strata of darker clay. These represent annual accumulations and thus provide a means for dating the sediments simply by counting the number of varves present. Artifacts, hearths, and faunal evidence are on the site.

Similar to the Siberian Dyuktai Diuktai culture and defined by H. West in , it is characterized by wedge-shaped microcores, microblades, burins, and bifacial points, scrapers on flakes, and large blades. A chemical dark-colored crust or film of iron and manganese oxides usually with some silica that is deposited on exposed rocks, artifacts, and petroglyph surfaces.

Of bacterial origin, this varnish becomes polished by wind abrasion can be used in cation ratio dating; its organic matter can be analyzed by accelerator mass spectrometer radiocarbon dating. They differ from the classic Oldowan industry in the types of stone artifacts. The final continental glacial advance, dating to c ,, BP, especially referring to a group of British deposits, stratified above Ipswichian Interglacial deposits.

Much of northern England, Scotland, and Wales is covered by a blanket of Devensian tills, sands, and gravels and these sediments were deposited by the ice-sheet.

South of the ice-sheet margin is a series of related pro-glacial and periglacial deposits. Most of the Devensian stage can be dated using radiocarbon, and by this means it has been correlated with the Weichselian in northwest Europe and the Wisconsin in North America.

All these formations represent one cold stage and directly preceded our present period of predominantly warm climate the Flandrian or Holocene. Not all of the Devensian deposits are strictly glacial; some contain abundant fossils which indicate warmer interstadial periods. Three interstadials have been defined in Britain: Levallosian, Mousterian, and Upper Palaeolithic artifacts are found in Devensian deposits and bones of Homo Sapiens have been found in Devensian cave sediments.

A limestone cave near the southwest coast of Western Australia, containing deep, well-preserved organic and stone deposits dating from 27,, BC. It is one of the longest occupation sequences in Australia, with well-defined hearths and occupation floors and a rich faunal assemblage. The stone assemblage included cores, scrapers, denticulate flakes, retouched flakes, and adze flakes of chert or quartz.

Undersea-drill cores from the nearby continental shelf have produced the same Eocene chert from a zone which would have been exposed during Pleistocene low sea-levels.

Three unifacially incised limestone plaques 10,, BC and a piece of artificially perforated marl have been interpreted as ritual items or adornments.

A limestone shelter in cliffs beside the lower Murray River in South Australia with a deposit rich in faunal material as well as stone and bone tools and dating to c BC. It was the first systematic archaeological excavation in Australia Interpretation of the stratigraphy and stone tool sequence at two sites introduced concepts of antiquity and cultural change in Aboriginal prehistory which had previously been denied in Australian anthropology.

A temple site in Miletus, Turkey, dating to the 8th century BC. The reconstructed Hellenistic temple included a naiskos inside the adyton.

The occupation had pottery, flakes with edge-gloss, and postholes of small square houses, and items paralleled in Taiwanese Neolithic sites. Excavation uncovered seven complete house-plans of the Late Vinca village, including one house containing pots. The subsistence economy was based on cattle husbandry and agriculture. Cult objects included a model ritual scene and many fired clay anthropomorphic figurines. In antiquity especially in France , a word for a megalithic tomb consisting of orthostats and capstone or for megalithic chamber tombs in general.

This was usually a stone structure consisting of upright columns supporting a slab roof and known from Neolithic times. The word has a second meaning for the enclosure for burial in a jar of the Yayoi period in Japan consisting of a single large stone slab supported on a ring of stones. A third meaning is for a megalithic stone burial feature in western China and coast Yellow Sea area, dating to the 1st millennium BC , of which there are three forms -- raised table, low table, and unsupported capstone.

A Neolithic site in Thailand where stone-working was done near chalcedony quarries, dating to the 3rd millennium BC. Tools made included flaked adzes utilized flakes. Characteristic are large incised cast-bronze drums, bronze situlae buckets , bells, tools, and weapons from elaborate boat burials and assemblages in lacquered wood coffins.

Dong-son drums of presumed Vietnamese manufacture were traded through wide areas of Southeast Asia and southern China to as far as New Guinea , and the Dong-son bronze-working tradition was by far the richest and most advanced ever to develop in Southeast Asia. Iron was used for tools. There is evidence for developing urbanism in defensive earthworks and wet rice cultivation. Hunters of food and marine shellfish can be seen in cave art at Dos Aguas.

More than 7, figures painted by these hunters and gatherers are known from all over the eastern and southern peninsula, dating from BC. Located in the open air, usually beneath rock overhangs or in protecting hollows, are animated representations of people dancing, including two women in voluminous skirts at Dos Aguas. A Numidian settlement, the best-preserved ancient Roman city in modern Tunisia, located near modern Tabursuq, west of the ancient road between Carthage and Theveste.

It was a dependency of Carthage until the 3rd century AD. It is a three-story building topped by a pyramid and the mausoleum contained a bilingual Phoenician and Numidian inscription.

It represented a combination of the Egyptian pyramidal funerary building and the Hellenistic Greek temple. Thugga was made a municipium by the Roman emperor Septimius Severus reigned AD , and an arch erected in his honor is one of the outstanding Roman remains. Other important buildings dating to Roman times include a forum, baths, villas, capitol, circus, temples, an aqueduct and system of water cisterns , and a theater.

An American astronomer who developed the dendrochronology dating method. He outlined the method as early as , but it was not until that he was able to publish an unbroken sequence of tree-rings for the Southwest US, extending back from the present day to the early years of the present era.

This provided a dating method for the southwestern Pueblo villages. A series of cold climatic phases in northwestern Europe, during a time when the North Atlantic was in almost full glacial condition. It is named after a tundra plant. The increasing temperature after the late Dryas period during the Pre-Boreal and the Boreal c BC , according to radiocarbon dating caused a remarkable change in late glacial flora and fauna.

- Fluorine uranium nitrogen dating

Bricks can be used as dating criteria, especially when they bear stamped inscriptions. They differ from the classic Oldowan industry in the types of stone artifacts. Their bones also were frequently found in association with our human and primate ancestors. He was largely responsible for demonstrating the existence of a pre-Mycenaean Aegean civilization, for naming it Minoan after the legendary King Minos of Creteand for revealing most of its characteristics. It was abandoned soon after the Roman conquest. How Does Radiocarbon Dating Work? - Instant Egghead #28

Typological sequencing cross dating Classification of datings into types Similar artifacts are grouped together Relative dates are assigned to an uranium if it matches other artifacts already recognized within a well established typological system.

There are approximately engravings of animals and red or black hand prints. Fluorine uranium nitrogen dating - Detailed composition: abundance of the elements in seawater; Salinity: the main salt ions making the sea salty; Density: the density of sea water depends on.

After hydrogen, helium is the second lightest and second most abundant element in the observable universe, being present at about 24% of the total . There are several chemical methods for relative dating: fluorine dating measures the amount of fluorine absorbed from groundwater since burial, and nitrogen dating. If they do not, they most likely come from different eras, despite the fact that they were found in association with each other.

There were also objects of silver and gold. Fluorine absorption dating is a method used to Many instances of this dating method compare the amount of fluorine and uranium in the bones to nitrogen dating to.
