1.4" Saurodon (Cretaceous Fish) Lower Jaw Section - Kansas

This is a fossil Saurodon jaw section with teeth from the Smoky Hill Chalk in Gove County, Kansas. All the teeth are broken but the roots are still imbedded into the bone. If you look closely there is a single whole tooth just below the bone line.

Saurodon is a genus of Carnivorous fish that swam in the world‭’‬s oceans during the Late Cretaceous.‭ ‬Saurodon had a long and slender body similar to the modern day barracuda.‭ ‬Also like a barracuda,‭ ‬the lower jaw of Saurodon projected in front of the upper,‭ ‬though in Saurodon this projection was far more extreme,‭ ‬and in some specimens this lower jaw is just beyond double the length of the upper jaw.‭

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.
