Pre-Clovis civilization in Florida; settlement 1,500 years earlier than previously believed

The discovery of stone tools alongside mastodon bones in a Florida river shows that humans settled the southeastern United States as much as 1,500 years earlier than scientists previously believed, according to a new research. This site on the Aucilla River — about 45 minutes from Tallahassee — is now the oldest known site of human life in the southeastern United States. It dates back 14,550 years.
