3" Fossil Mosasaur (Platecarpus) Jaw Section with Teeth - Kansas

This is a 3" long, jaw section of a Mosasaur (Platecarpus sp.) from the Late Cretaceous, Smoky Hill Chalk in Gove County, Kansas. Platecarpus is an extinct aquatic lizard belonging to the mosasaur family. This specimen features two teeth that do not appear to be composites.

This specimen comes with an acrylic display stand.

Platecarpus fossils have been found in the United States and in Belgium and Africa. They reached lengths of up to 14 feet long, half of that length being its tail. Platecarpus probably fed on fish, squid and ammonites. Like other mosasaurs, it was initially thought to have swam in an eel-like fashion, although a recent study suggests that it swam more like modern sharks.

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.
