Chiquihuite Cave
Chiquihuite Cave is a possible Upper Paleolithic archaeological site in the Astillero Mountains, Zacatecas State, in North-Central Mexico. Chiquihuite Cave may be evidence of early human presence in the Western Hemisphere up to 33,000 years ago. It is located 2,740 meters (9000 feet) above sea level and about 1 kilometer higher than the valley below. The lithic artifacts discovered here have been dated to 26,000 years ago based on more than 50 samples of animal bone and charcoal found in association with the tools. There is scholarly debate over whether the artifacts should be considered evidence of human activity or if they were formed naturally. Excavation history Excavations were started in 2012, when a test pit unearthed unusual stone artifacts. Further excavations were carried out in an expanded 3-meter-deep excavation unit in 2016 and 2017 under the leadership of Dr. Ciprian Ardelean of the Autonomous University of Zacatecas (Mexico). Dr. Ardelean’s team recovered 1,930 ston ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Paleolithic
The Upper Paleolithic (or Upper Palaeolithic) is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 12,000 years ago (the beginning of the Holocene), according to some theories coinciding with the appearance of behavioral modernity in early modern humans, until the advent of the Neolithic Revolution and agriculture. Anatomically modern humans (i.e. ''Homo sapiens'') are believed to have emerged in Africa around 300,000 years ago, it has been argued by some that their ways of life changed relatively little from that of archaic humans of the Middle Paleolithic, until about 50,000 years ago, when there was a marked increase in the diversity of Artefact (archaeology), artefacts found associated with modern human remains. This period coincides with the most common date assigned to early human migrations, expansion of modern humans from Africa throughout Asia and Eurasia, which contributed to the Neanderthal extinction, ex ...

Bluefish Caves
Bluefish Caves is an archaeological site in Yukon, Canada, located southwest of the Vuntut Gwichin community of Old Crow, from which a jaw bone of a Yukon horse has been radiocarbon dated to 24,000 years before present (BP). There are three small caves in the area. Context Bluefish Cave was initially known to the local First Nations, but was popularized by a fishing expedition in 1976, and later by researchers. This site is made up of three small caves, ranging from . The first cave contains various animal bones that appear to have been dragged there by predators; findings of tool marks and some tools themselves point to a human presence. The Old Crow Flats, another important area with early human presence, are located about 75 km northeast of the Bluefish Caves. Dating The site was excavated by archaeologist Jacques Cinq-Mars between 1977 and 1987, and the initial radiocarbon dating suggested an age of 24,000 before present (BP). This was considered controversial as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meadowcroft Rockshelter
Meadowcroft Rockshelter is an archaeological site located near Avella in Jefferson Township, Pennsylvania. The site is a rock shelter in a bluff overlooking Cross Creek (a tributary of the Ohio River), and contains evidence that the area may have been continually inhabited for more than 19,000 years. If accurately dated, it would be one of the earliest known sites with evidence of a human presence and continuous human occupation in the New World. The site is located 27 miles west-southwest of Pittsburgh in the Pittsburgh metropolitan area. The site operates as a division of the Heinz History Center of Pittsburgh and has a museum and a reconstruction of a circa 1570s Monongahela Culture Indian village. Meadowcroft Rockshelter is recognized as a National Historic Landmark, a Pennsylvania Commonwealth Treasure, and as an official project of Save America's Treasures. Geology and location The rockshelter is a natural formation beneath an overhanging cliff of Morgantown-Connellsv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Settlement Of The Americas
The settlement of the Americas began when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26,000 to 19,000 years ago). These populations expanded south of the Laurentide Ice Sheet and spread rapidly southward, occupying both North and South America, by 12,000 to 14,000 years ago. The earliest populations in the Americas, before roughly 10,000 years ago, are known as Paleo-Indians. Indigenous peoples of the Americas have been linked to Siberian populations by linguistic factors, the distribution of blood types, and in genetic composition as reflected by molecular data, such as DNA. While there is general agreement that the Americas were first settled from Asia, the pattern of migration and the place(s) of origin in Eurasia of the peoples who migrated to the Americas remain unclear ...

Geofact
A geofact (a portmanteau of ''geology'' and ''artifact'') is a natural stone formation that is difficult to distinguish from a man-made artifact. Geofacts could be fluvially reworked and be misinterpreted as an artifact, especially when compared to paleolithic artifacts. Some of the proposed criteria for distinguishing geofacts from artifacts for paleolithic specimens resembling debitage have been subjected to evaluation by experimental and actualistic studies. If the artifact has two or more of the following, then the artifact is more than likely to be a geofact. Possible examples include several purported prominent ancient artifacts, such as the Venus of Berekhat Ram and the Venus of Tan-Tan The Venus of Tan-Tan (supposedly, 500,000-300,000 BP) is an alleged artifact found in Morocco. It and its contemporary, the Venus of Berekhat Ram, have been claimed as the earliest representations of the human form. Description The Venus of Ta .... These are thought by many in the arc ...

Toca Da Tira Peia
Toca da Tira Peia is a rock shelter site, located in the municipality Coronel José Dias, Piauí state, near the Serra da Capivara National Park, Brazil, thought to hold evidence of prehistoric human presence in South America dating to 22,000 years ago. Site The Toca da Tira Peia rockshelter was discovered in 2008. There are four well preserved sediment layers, the youngest of which dates to 4,000 years BP. 113 knapped stone tools and artifacts have been recovered. The site has been dated through optically stimulated luminescence technique. "Digging turned up 113 stone artifacts consisting of tools and tool debris in five soil layers. Using a technique that measures natural radiation damage in excavated quartz grains, the scientists estimated that the last exposure of soil to sunlight ranged from about 4,000 years ago in the top layer to 22,000 years ago in the third layer." According to the authors, this site offers some advantages to the other sites such as Pedra Furada i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santa Elina Shelter
Santa Claus, also known as Father Christmas, Saint Nicholas, Saint Nick, Kris Kringle, or simply Santa, is a legendary figure originating in Western Christian culture who is said to bring children gifts during the late evening and overnight hours on Christmas Eve of toys and candy or coal or nothing, depending on whether they are "naughty or nice". In the legend, he accomplishes this with the aid of Christmas elves, who make the toys in his workshop, often said to be at the North Pole, and flying reindeer who pull his sleigh through the air. The modern figure of Santa is based on folklore traditions surrounding Saint Nicholas, the English figure of Father Christmas and the Dutch figure of ''Sinterklaas''. Santa is generally depicted as a portly, jolly, white-bearded man, often with spectacles, wearing a red coat with white fur collar and cuffs, white-fur-cuffed red trousers, red hat with white fur, and black leather belt and boots, carrying a bag full of gifts for childr ...

Arctodus
''Arctodus'' is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,000 years ago). There are two recognized species: the lesser short-faced bear (''Arctodus pristinus'') and the giant short-faced bear (''Arctodus simus''). Both species are relatively rare in the fossil record- ''A. pristinus'' was largely restricted to the Early Pleistocene of the eastern United States, whereas ''A. simus'' had a cosmopolitan range, with most finds being from the Late Pleistocene of the US, Mexico and Canada. ''A. simus'' evolved from ''A. pristinus'', but both species likely overlapped in the Middle Pleistocene. Of these species, ''A. simus'' was larger, is known from more complete remains, and is considered one of the most charismatic of North America's megafauna. Today considered to be an enormous omnivore, ''Arctodus simus'' is believed to be one of the largest known terrestrial mammalian carnivorans that has ever existed. However, ''Arct ...
