Michael Waters is an archaeologist at Texas A&M University in College Station. Scuba divers collected twigs, seeds and plant fragments from submerged layers of sediment.

The two led a team that recovered from a sinkhole in the Aucilla River. Researchers then dated the material based on traces of radioactive carbon in these samples.

That let them determine that six stone artifacts excavated by the divers were about 14,550 years old.

These big animals died out roughly 12,600 years ago.

The Page-Ladson site “is one of the best cases for pre-Clovis archaeology in the Americas,” concludes Vance Holliday.

He is an archaeologist who works at the University of Arizona in Tucson.

A group of Stone Age people butchered a mastodon — or at least scavenged its carcass — some 14,550 years ago.

These were hunter-gatherers that lived on what is now Florida’s Gulf Coast.

Researchers discovered their stone tools in an underwater sinkhole.The finds may help scientists resolve when humans first came to the Americas.For much of the 20th century, scientists thought that the first people to inhabit North America were the Clovis.These people showed up in North America roughly 13,000 years ago.They were named for their distinctive stone tools, found near Clovis, N. But evidence has been mounting that the Clovis were not the first North Americans.Jessi Halligan is an archaeologist at Florida State University in Tallahassee.
