Picture Tennessee covered by a shallow ocean filled with sharks, ancient clams, and bizarre marine reptiles. That world existed around 70 million years ago during the Cretaceous Period, and the proof is buried in the ground near Adamsville. At Coon Creek Science Center, you can dig up real fossils from that underwater era and hold creatures that swam where you now stand.
It’s one of the few places in the country where everyday visitors get to keep what they find, making it a memorable stop for anyone curious about deep time.
A Tennessee Fossil Site With an Ancient Sea Story
West Tennessee doesn’t look like an ocean floor today, but millions of years ago, a warm shallow sea stretched across this region. Coon Creek Science Center sits on land that preserves one of the best records of that vanished world. The fossils here come from the Late Cretaceous, a time when dinosaurs still roamed continents but this part of Tennessee was submerged beneath waves.
What makes this site remarkable is the quality and variety of specimens. You’ll find shells from ancient clams, snails, and oysters alongside shark teeth and pieces of marine reptiles. The sediment here trapped these creatures in fine detail, so even delicate features survived intact…
