A fish-eat-fish world: Dunkleosteus and other creatures from the Cleveland Shale

The Cleveland Shale is a well-known deposit from the Devonian Period, also known as the Age of Fishes, where fossils of numerous fish are uncovered, including the famous Dunkleosteus.
Dunkleosteus belonged to a diverse group of fish called placoderms, which dominated the Devonian seas before going extinct during the second major mass extinction in Earth’s history.
Another group of fish, the sharks, are also well preserved in the Cleveland Shale and were prey to the fearsome Dunkleosteus. Travel back in time to the Late Devonian, approximately 360
million years ago, to learn about the apex predator, Dunkleosteus. Discover what made this fish so unique and formidable and learn about the other fish, some familiar and some bizarre, that
coexisted in the ancient marine ecosystem.
