Peace River — Rockhounding in DeSoto County, Florida

Updated July 2026

The Peace River was a shark nursery during the Miocene and later ran through Ice Age Florida, so its gravel bars carry fossil shark teeth, including large megalodon teeth, alongside mammoth, mastodon, and other Pleistocene mammal fossils. The stretch near Arcadia and Zolfo Springs is the best known, reached from public boat ramps and canoe liveries. Fossil hunting is best in the dry season, October through April, when low water exposes the gravel. Reported finds include shark teeth, megalodon teeth, fossils, mammoth, mastodon.
