Fossil Squalicorax Tooth - North Carolina

Here's a cretaceous aged fossil shark tooth from Squalicorax pristodontus, commonly known as a crow shark. It comes from the Black Creek Formation of North Carolina.

Squalicorax pristodontus is the largest species of the genus, measuring approximately 3-5 meters as adults. It 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.
