Smilodon

Fossils

The museum holds many fossils in which you will discover more about mosasaurs, plesiosaurs, Xiphactinus and other Cretaceous period animals. You can touch the fossilized femur of Camarasaurus, learn about the evolution of ancient plants and trees, discover invertebrate fossils, and more.

Mosasaur

Mosasaurs

Contrary to popular belief, not all prehistoric fossils found are dinosaurs. The largest mosasaur found was discovered in Kansas and a cast of this fossil looms over the 4th floor museum entrance.  The mosasaur breathed air, but did not come onto land. They swam using a tail movement, similar to how snakes move. You can find more about mosasaurs in detail on the 3rd and 5th floors.

Xiphactinus

Xiphactinus

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.

Pteranodon

Pteranodon

The Pteranodon belongs to an extinct group of reptiles called pterosaurs. They were the first vertebrates to evolve powered flight. This species was first discovered in Kansas in 1870. The one featured at our museum would have weighed about 45 pounds.
