1.65" Fossil Mosasaur (Clidastes) Cervical Vertebra - Kansas
This is a 1.65" wide cervical vertebra from Clidastes velox (propython), a species of Mosasaur. It was collected from the Smoky Hill Chalk in Gove County, Kansas.
Clidastes is an extinct aquatic lizard belonging to the mosasaur family. Clidastes was a one of the smaller types of mosasaurs. Although some species were larger, the average length of this genera is only a few meters, perhaps 10 feet in length. This mosasaur was also slimmer than the others, the rib cage was narrower, giving it a more sleek, or eel like look. It was probably very agile, and able to chase down smaller prey.

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.
