In the History of Mesoamerica, the stage known as the Paleo-Indian period is the era in the scheme of Mesoamerican chronology which begins with the very first indications of human habitation within the Mesoamerican region, and continues until the general onset of the development of agriculture and other proto-civilisation traits. The conclusion of this stage may be assigned to approximately 9000 BP, and the transition to the succeeding Archaic period is not a well-defined one.
Clovis points are the characteristically fluted projectile points associated with the New World Clovis culture, a prehistoric Paleo-American culture. They are present in dense concentrations across much of North America and they are largely restricted to the north of South America. There are slight differences in points found in the Eastern United States bringing them to sometimes be called "Clovis-like". Clovis points date to the Early Paleoindian period, with all known points dating from roughly 13,400–12,700 years ago. As an example, Clovis remains at the Murry Springs Site date to around 12,900 calendar years ago. Clovis fluted points are named after the city of Clovis, New Mexico, where examples were first found in 1929 by Ridgely Whiteman.
Clovis culture is a prehistoric Paleoamerican archaeological culture, named for distinct stone and bone tools found in close association with Pleistocene fauna, particularly two Columbian mammoths, at Blackwater Locality No. 1 near Clovis, New Mexico, in 1936 and 1937, though Paleoindian artifacts had been found at the site since the 1920s. It existed from roughly 11,500 to 10,800 BCE near the end of the Last Glacial Period.
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.
The Page–Ladson archaeological and paleontological site (8JE591) is a deep sinkhole in the bed of the karstic Aucilla River that has stratified deposits of late Pleistocene and early Holocene animal bones and human artifacts. The site was the first pre-Clovis site discovered in southeastern North America; radiocarbon evidence suggests that the site dates from 14,200 to 14,550 BP. These dates are roughly 1,000 to 1,500 years before the advent of the Clovis culture. Early dates for Page–Ladson challenge theories that humans quickly decimated large game populations in the area once they arrived.
Cactus Hill is an archaeological site in southeastern Virginia, United States, located on sand dunes above the Nottoway River about 45 miles south of Richmond. The site receives its name from the prickly pear cacti that can be found growing abundantly on-site in the sandy soil. Cactus Hill may be one of the oldest archaeological sites in the Americas. If proven to have been inhabited 16,000 to 20,000 years ago, it would provide supporting evidence for pre-Clovis occupation of the Americas. The site has yielded multiple levels of prehistoric inhabitance with two discrete levels of early Paleo-Indian activity.
The Stanfield-Worley Bluff Shelter, located on private property in Colbert County in northwestern Alabama, United States, is one of the most important prehistoric sites excavated in the state due to the archeological evidence deposited by the Paleo-Indians who once occupied the rock shelter. Lying in Sanderson Cove along a tributary of Cane Creek approximately seven miles (11 km) south of the Tennessee Valley, the shelter and the high bluffs of the surrounding valley provided a well-protected environment for the Native American occupants.
James M. Adovasio is an American archaeologist and one of the foremost experts in perishable artifacts. He was formerly the Provost, Dean of the Zurn School of Natural Sciences and Mathematics, and Director of the Mercyhurst Archaeological Institute at Mercyhurst University in Erie, Pennsylvania, Adovasio is best known for his work at Meadowcroft Rockshelter in Pennsylvania and for his subsequent role in the "Clovis First" debate. He has published nearly 400 books, monographs, articles, and papers in his field.
The Senator John Heinz History Center, an affiliate of the Smithsonian Institution, is the largest history museum in the Commonwealth of Pennsylvania, United States. Named after U.S. Senator H. John Heinz III (1938–1991) from Pennsylvania, it is located in the Strip District of Pittsburgh.
The Lindenmeier site is a stratified multi-component archaeological site most famous for its Folsom component. The former Lindenmeier Ranch is in the Soapstone Prairie Natural Area, in northeastern Larimer County, Colorado, United States. The site contains the most extensive Folsom culture campsite yet found with calibrated radiocarbon dates of c. 12,300 B.P.. Artifacts were also found from subsequent Archaic and Late pre-historic periods.
The Paisley Caves or the Paisley Five Mile Point Caves complex is a system of eight caves in an arid, desolate region of south-central Oregon, United States north of the present-day city of Paisley, Oregon. The caves are located in the Summer Lake basin at 4,520 feet (1,380 m) elevation and face west, carved into a ridge of Miocene and Pliocene era basalts mixed with soft volcanic tuffs and breccias by Pleistocene-era waves from Summer Lake. One of the caves may contain archaeological evidence of the oldest definitively-dated human presence in North America. The site was first studied by Luther Cressman in the 1930s.
The Thunderbird Archaeological District, near Limeton, Virginia, is an archaeological district described as consisting of "three sites—Thunderbird Site, the Fifty Site, and the Fifty Bog—which provide a stratified cultural sequence spanning Paleo-Indian cultures through the end of Early Archaic times with scattered evidence of later occupation."
The Manis Mastodon site is a 2-acre (1 ha) archaeological site on the Olympic Peninsula near Sequim, Washington, United States, discovered in 1977. During the 1977-78 excavation, the remains of an American mastodon were recovered with a 13,800-year-old projectile point made of the bone from a different mastodon embedded in its rib. The site was placed on the National Register of Historic Places in 1978.
The Windust Caves (45-FR-46) are a series of nine caves eroded into a basalt cliff on the north side of the lower Snake River in Franklin County, southeastern Washington. The caves were excavated from 1959 until 1961 by a crew led by Harvey S. Rice. The site contains cultural artifacts dating back over 10,000 years and is culturally associated with other sites in the Columbia Basin.
The LoDaisKa site is a prominent archaeological site in the U.S. state of Colorado, located within a rockshelter near Morrison. The rockshelter was first inhabited by people of the Archaic through the Middle Ceramic period, generally spanning 3000 BC to 1000 AD.
The Buttermilk Creek complex is the remains of a paleolithic settlement along the shores of Buttermilk Creek in present-day Salado, Texas. The assemblage dates to ~13.2 to 15.5 thousand years old. If confirmed, the site represents evidence of human settlement in the Americas that pre-dates the Clovis culture.
Hell Gap is a deeply stratified archaeological site located in the Great Plains of eastern Wyoming, approximately thirteen miles north of Guernsey, where an abundant amount of Paleoindian and Archaic artifacts have been found and excavated since 1959. This site has had an important impact on North American archaeology because of the large quantity and breadth of prehistoric Paleoindian and Archaic period artifacts and cultures it encompasses. It was designated a National Historic Landmark in 2016.
Michael Waters is an American academic working as a professor of anthropology and geography at Texas A&M University, where he holds the Endowed Chair in First American Studies. He specializes in geoarchaeology, and has applied this method to the investigation of Clovis and later Paleo-Indian, and possible pre-Clovis occupation sites.
The Gault archaeological site is an extensive, multicomponent site located in Florence, Texas, United States on the Williamson-Bell County line along Buttermilk Creek about 250 meters upstream from the Buttermilk Creek complex. It bears evidence of human habitation for at least 20,000 years, making it one of the few archaeological sites in the Americas at which compelling evidence has been found for human occupation dating to before the appearance of the Clovis culture. Archaeological material covers about 16 hectares with a depth of up to 3 meters in places. About 30 incised stones from the Clovis period engraved with geometric patterns were found there as well as others from periods up to the Early Archaic. Incised bone was also found.
Paleo Crossing site, also known as the Old Dague Farm site, is an archaeological site near Sharon Center, Ohio in Medina County where Clovis artifacts dated to 10,980 BP ± 75 years Before Present were found. The Cleveland Museum of Natural History conducted an excavation from 1990 to 1993. The site provides evidence of Paleo-Indians in northern Ohio and may be the area's oldest residents and archaeologist Dr. David Brose believes that they may be "some of the oldest certain examples of human activity in the New World." The site contains charcoal recovered from refuse pits. There were also two post holes and blades and tools 80% of which were made from flint from the Ohio River Valley in Indiana, 500 miles from Paleo Crossing, which indicates that the hunter-gatherers had a widespread social network and traveled across distances relatively quickly. The post holes are evidence that there was a shelter built on the site.
