Science Underwater archaeological site recasts 'peopling of the Americas' narrative

Stone tools, mastodon bones, and dung provide 'vindication' for 30-year-old Florida underwater archaeological dig site that had presented evidence that the Americas were populated much earlier than originally thought.

Deep in an underwater sinkhole in a river in Florida, archaeologists found the remains of a prehistoric population of humans that lived in the region 14,550 years ago. Stone tools, mastodon bones with distinct cut marks, and mastodon dung hold enticing clues into the lives of these early Americans and the megafauna around them. Those new findings are reported in a paper published Friday in the journal Science Advances.
