That makes the ancient sinkhole the earliest well-documented site for human presence in the southeastern U.S., and important for understanding the settling of the Americas, experts said.
The findings confirm claims made more than a decade ago about the site, some 30 miles southeast of Tallahassee. At that time, researchers reported evidence that humans were there some 14,400 years ago. But in an era when such an old date was widely considered impossible, other experts disputed the evidence, said Mike Waters of Texas A&M University in College Station.
The sinkhole was “just politely ignored,” he said.
Waters was among a new team of scientists who excavated there from 2012 to 2014. They report finding the knife and stone flakes in a paper released Friday by the journal Science Advances. The new work offers “far better” evidence for early humans than the earlier research did, he said.
