The Page-Ladson archaeological and paleontological site (8JE591) is a deep sinkhole in the bed of the karstic Aucilla River (between Jefferson and Taylor counties in the Big Bend region of Florida) that has stratified deposits of late Pleistocene and early Holocene animal bones and human artifacts. The site was the first pre-Clovis site discovered in southeastern North America; radiocarbon evidence suggest that the site date from 14,200 to 14,550 BP. These dates are roughly 1,000 to 1,500 years before the advent of the Clovis culture. Early dates for Page-Ladson challenge theories that humans quickly decimated large game populations in the area once they arrived.
