Bone Valley (Polk County phosphate region)
Central Florida's phosphate mining belt — the world-famous fossil bed that supplies most of the megalodon teeth on the dealer market. Direct mine access is industrial-only, but reclaimed lands, fossil parks, and creek tributaries downstream of the district are open to hunters.
Hunt the Peace River and its tributaries (especially Bowlegs Creek and downstream of Bartow / Mulberry) with a sifter and shovel during low water. Reclaimed phosphate land at Mosaic Fossil Park and Tenoroc reveals fresh material after rain. Always follow current state water-bottom permit rules.
Active phosphate mines (Mosaic, etc.) are off-limits. Public hunting on the Peace River and tributaries; some reclaimed sites open by permit. Mosaic Peace River Fossil Park reopens periodically — check the schedule.
Florida requires a state Vertebrate Fossil Permit ($5/year) to collect vertebrate fossils on state-owned waters and lands. Invertebrates are unrestricted. Stay off active mine property.
- Alligators
- Slick mud and steep banks
- Sun and dehydration
- Snake encounters
- Permits are cheap and required — get yours from Florida Museum of Natural History before you go
- Sift in tributary mouths and gravel bars where flow drops
- Black, lustrous surfaces and characteristic phosphate matrix are the giveaway
