Archaeologists do not agree on whether the widespread presence of these artifacts indicates the proliferation of a single people, or the adoption of a superior technology by diverse population groups.

The culture is named after artifacts found between 19 at Blackwater Locality No.

Clovis people are generally accepted to have hunted mammoths as well as extinct bison, mastodon, gomphotheres, sloths, tapir, camelops, horse and other smaller animals.

More than 125 species of plants and animals are known to have been used by Clovis people in the portion of the Western Hemisphere they inhabited.

In 2011, remains of gomphotheres were found; the evidence suggests that humans did, in fact, kill two of them there.

Also, the Aubrey site in Denton County, Texas, produced an almost identical radiocarbon date.

The most commonly held perspective on the end of the Clovis culture is that a decline in the availability of megafauna, combined with an overall increase in a less mobile population, led to local differentiation of lithic and cultural traditions across the Americas.

On August 29, 1927, they found the first in situ Folsom point with the extinct B. This confirmation of a human presence in the Americas during the Pleistocene inspired many people to start looking for evidence of early humans.This appears to have been triggered by a vast amount of meltwater – possibly from Lake Agassiz – emptying into the North Atlantic, disrupting the thermohaline circulation.The Younger Dryas impact hypothesis or Clovis comet hypothesis originally proposed that a large air burst or earth impact of a comet or comets from outer space initiated the Younger Dryas cold period about 12,900 BP calibrated (10,900 The hypothesis has been largely contradicted by research showing that most of the findings cannot be repeated by other scientists, and criticized because of misinterpretation of data and the lack of confirmatory evidence.The publications on Burnet Cave and Blackwater Draw directly contradict statements by several authors (for example see Haynes 20 The Early Settlement of North America) that Dent, Colorado was the first excavated Clovis site.The Dent Site, in Weld County, Colorado, was simply a fossil mammoth excavation in 1932.A hallmark of the toolkit associated with the Clovis culture is the distinctively shaped, fluted stone spear point, known as the Clovis point.
