New underwater archaeologists from Texas A & M and University of Tennessee have discovered the mastodons and humans lived together in Florida. They found mastodon bones and stone tools in the same sink hole. They found it in Aucilla River in North Florida.
Also, “the researchers say, the discovery on an unmistakable human artifact, a stone knife fragment, embedded in sand and dung that allowed for exact dating, proves that paleoindians, as archaeologists call the first people to come to North America, colonized northern Florida by 14,550 years ago.”
This research has been described as superb archaeological scholarship. The same pond also probably included ancient bison and rhinoceroses. This is awesome.
