3.07" Fossil Fish (Ichthyodectes) Jaw Section - Kansas

This is a 3.07" wide, fossil jaw section of an Ichthyodectes fish from the Smoky Hill Chalk of Gove County, Kansas. This bone has good preservation and beautiful color. Aside from a couple repaired cracks, there is very little restoration on this awesome piece.

Ichthyodectes was a bony fish of the order Ichthyodectiformes, which in addition to Ichthyodectes includes the giant, Xiphactinus and smaller Gillicus. Large ichthyodectes grew to more than 10 feet long and were a one of the principle predators of the Western Interior Seaway during the late Cretaceous Period.
