.9" Fossil Crow Shark (Squalicorax) Tooth - Kansas

This is a .9" long fossil crow shark (Squalicorax) tooth from the Smoky Hill Chalk (Niobrara Formation) in Gove County, Kansas. The tooth is Late Cretaceous in age, or approximately 83 million years old. The tooth is in excellent condition and rests on the rock in which it was found.

Comes with an acrylic display stand.

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.

The Smoky Hill Chalk Member of the Niobrara Chalk formation is a Cretaceous conservation Lagerstätte, or fossil rich geological formation, known primarily for its exceptionally well-preserved marine reptiles. It outcrops in parts of northwest Kansas, its most famous localities for fossils, and in southeastern Nebraska. Large well-known fossils excavated from the Smoky Hill Chalk include marine reptiles such as plesiosaurs, large bony fish such as Xiphactinus, mosasaurs, pterosaurs, and turtles.
