3" Associated Fossil Fish Vertebrae - Smoky Hill Chalk, Kansas
This is a string of six associated fossil fish vertebrae from the Late Cretaceous Smoky Hill Chalk in Kansas. The string is 3" long and about 1" wide.
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.
