Contrary to popular belief, not all prehistoric fossils are dinosaurs. The largest mosasaur found, Tylosaurus, was a marine reptile fossil discovered in Kansas and is the Official State Marine Fossil of Kansas. A 45-foot-long cast of this fossil looms over the 4th floor museum entrance. You can find more about mosasaurs on the 3rd and 5th floors.
The 16-foot long Xiphactinus featured on the 3rd floor is a giant, bony fish with jagged teeth. It once swam in the sea that covered present day Kansas. It was first discovered in Kansas in the 1850s.
Pterandon is the Official State Flying Fossil of Kansas. The exhibit was updated in 2023, and in addition to the Pteranodon, now includes a video demonstrating why and how Pterosaurs flew, a skull, a pelvis and more.
