1.7" Fossil Pterosaur (Pteranodon) Phalange Section- Kansas

Fossil Pterosaur (Pteranodon) Phalange Section- Kansas #115209

This is a 1.7" long pterosaur (Pteranodon) phalange (finger/wing bone) section from the Smokey Hill Chalk in Gove County, Kansas. It is deformed from the preservation process but is in good condition. This is the proximal end of a bone in the claw on the wing. It is analogous to a finger bone in humans

Pteranodon is a genus of pterosaurs which included some of the largest known flying reptiles, with wingspans over 6 meters (20 ft). They lived during the late Cretaceous of North America in present-day Kansas, Alabama, Nebraska, Wyoming, and South Dakota. Pteranodon were pterosaurs, not dinosaurs. The pteranodon was designated as the official Kansas state flying fossil in 2014.

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.
