Pedra Furada Sites
Pedra Furada (, meaning pierced rock) is an important collection of over 800 archaeological sites in the state of Piauí, Brazil. These include hundreds of rock paintings dating from circa 12,000 years before present. More importantly, charcoal from very ancient fires and stone shards that may be interpreted as tools found at the location were dated from 48,000 to 32,000 years before present, suggesting the possibility of a human presence tens of thousand of years prior to the arrival of the Clovis people in North America (the latter dates are still under discussion, see Meltzer, 2021: 90-130). In 1973, a Brazilian and French team excavating a site located in the southeastern portion of what is now the Serra da Capivara National Park discovered the first finds. Brazilian archaeologist Niède Guidon reported the discovery in 1986. In 1991, Pedra Furada became a World Heritage Site. As of 2001, Guidon's findings were still considered controversial and not widely accepted by expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th c ...

Quartzite
Quartzite is a hard, non- foliated metamorphic rock that was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts, and hence quartzite is a metasandstone. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meadowcroft Rockshelter
The Meadowcroft Rockshelter is an archaeological site which is 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 twenty-seven 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.

Topper (archaeological Site)
Topper is an archaeological site located along the Savannah River in Allendale County, South Carolina, United States. It is noted as a location of artifacts which some archaeologists believe to indicate human habitation of the New World earlier than the Clovis culture. The latter were previously believed to be the first people in North America. Artifacts at this site may predate Clovis by 3,000 years or more, but these conclusions are disputed. The primary excavation has gone down to a level that dates to at least 50,000 B.C.E., searching for evidence of cultural artifacts. Until increasing challenges in the first decade of the 21st century to the Clovis theory based on this site and others, it was unusual for archaeologists to dig deeper than the layer of the Clovis culture, as they then believed that no human artifacts would be found older than Clovis. Geography The Topper site lies along the eastern side of the Savannah River. The site is somewhat hilly: the lowest section l ...

Santa Cruz Province, Argentina
Santa Cruz Province (, , "Holy Cross") is a Provinces of Argentina, province of Argentina, located in the southern part of the country, in Patagonia. It borders Chubut Province to the north, and Chile to the west and south, with the Atlantic Ocean, Atlantic coast to the east. Santa Cruz is the second-largest province of the country (after Buenos Aires Province), and the least Population density, densely populated in mainland Argentina. The indigenous people of the province are the Tehuelches, who despite European exploration from the 16th century onwards, retained independence until the late 19th century. Soon after the Conquest of the Desert in the 1870s, the area was organised as the Territory of Santa Cruz, named after its original capital in Puerto Santa Cruz. The capital moved to Rio Gallegos in 1888 and has remained there ever since. Immigrants from various European countries came to the territory in the late 19th and early 20th century Tierra del Fuego gold rush, during a go ...

Piedra Museo
Piedra Museo is an archaeological site in Santa Cruz Province, Argentina, and one of the earliest known archaeological remains in the Americas. Overview The site was discovered around 1910 by Argentine naturalist Florentino Ameghino, who wrote the first detailed anthropological study of Argentina, ''La antigüedad del hombre en el Plata'' (''The Antiquity of Man in the Río de la Plata Basin''), in 1878. A further 1995 excavation by University of La Plata archaeologist Dr. Laura Miotti made a carbon dating analysis possible, and led to the discovery that its human fossil remains date from approximately 11,000 years ago. The site, located 250 km (150 mi) from Pico Truncado, in Deseado Department ( Santa Cruz Province), is among the oldest archaeological remains uncovered in the Americas. Its discoveries included spear heads that contained traces of ''Mylodon'' and ''Hippidion'', among other animals known to have been extinct since at least 10000 BC. Its original inhabit ...

Monte Verde
Monte Verde is a Paleolithic archaeological site in the Llanquihue Province in southern Chile, located near Puerto Montt, Los Lagos Region. The site is primarily known for Monte Verde II, dating to approximately 14,550–14,500 calibrated years Before Present (BP). The Monte Verde II site has been considered key evidence showing that the human settlement of the Americas pre-dates the Clovis culture by at least 1,000 years. This contradicts the previously accepted "Clovis first" model which holds that settlement of the Americas began after 13,500 cal BP. The Monte Verde findings were initially dismissed by most of the scientific community, but the evidence then became more accepted in archaeological circles. The site also contains an older, much more controversial layer (Monte Verde I) suggested to date to 18,500 cal BP (16,500 BC), that lacks the general acceptance of Monte Verde II. Monte Verde II represents a campsite with wooden tent-like structures that was later covered b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Migration And Settlement Of The Americas From Asia
It is believed that the peopling of the Americas began when Upper Paleolithic, Paleolithic hunter-gatherers (Paleo-Indians) 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 Americas, North and South America no later than 14,000 years ago, and possibly even before 20,000 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 proposed Dene–Yeniseian languages, linguistic factors, the distribution of blood types, and in Genetic history of the Indigenous peoples of the Americas, genetic composition as reflected by Molecule, molecular data, such as D ...
