Asteracanthus was a large hybodont shark from the Late Jurassic, growing up to 10 feet long and equipped with distinctive dorsal fin spines and broad, crushing teeth. Unlike today’s sharks, Asteracanthus had a body built for maneuverability in shallow lagoons and reefs, likely feeding on shellfish, crustaceans, and slow-swimming prey.

With its unique spiny silhouette and prehistoric swagger, this model highlights a lesser-known but striking ocean predator. A perfect addition for collectors who want something different from the usual megalodon or mosasaur — Asteracanthus was a true relic of deep time.
