0.77" Fossil Shark (Squalicorax) Tooth - Kansas

This is a 0.77" long tooth of the crow shark Squalicorax falcatus from the Smoky Hill Chalk in Kansas. The fine serrations are still present and the tooth is in overall very good condition.

Squalicorax also referred to as a "crow shark", is an extinct lamniform shark that lived during the Cretaceous. It was medium size, typically about 2 meters in length and would have a body similar to most of todays mid water sharks (Blue, Mako, Great White).

During the Late Cretaceous, much of the middle of the United States was covered by the Western Interior Seaway effectively splitting the continent in two. The Niobrara Formation in Kansas is one of the best known localities for marine fossils deposited during this time. These fossils include the remains of giant marine predators including Mosasaurs, Plesiosaurs, sharks like Cretoxyrhina and the giant predatory fish Xiphactinus.
