1" Fossil Crow Shark (Squalicorax) Tooth - Texas

Squalicorax would have had a body type very similar to todays grey sharks but the teeth most closely resembled that of tiger sharks. It was likely a coastal predator, but there is evidence it was also a scavenger as evidenced by a Squalicorax tooth having been found embedded on the bone of a Hadrosaur. Hadrosaurs were terrestrial dinosaurs, so it likely had died on land and been swept out to see.
