Florida archaeological site yields clues to early civilization in southeast U.S.

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 research team led by a Florida State University professor.
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.
