Mineral Wells Fossil Park

What was once the City of Mineral Wells' landfill borrow pit turned out to be something far stranger: twenty-plus years of erosion peeled back the topsoil and exposed a 300-million-year-old Pennsylvanian sea floor sitting quietly in the Texas scrub. This free municipal park is one of the very few places in the US where you can legally dig up fossils — shark teeth, trilobites, crinoids, brachiopods, echinoids — and walk away with them in your pocket, no permit required. It's listed on Atlas Obscura and covered by Roadside America, which should tell you everything about its vibe. An hour west of Fort Worth, it gets almost none of the foot traffic it deserves, which means the shale is still genuinely productive for a patient digger.

The move: Pack a couple of flat-head screwdrivers and a brush, show up early before the Texas heat peaks, and spend a few hours cracking open shale layers in search of 300-million-year-old sea creatures — then argue over whose crinoid stem is more impressive on the drive back.
