The pteranodon wing pictured below is only one of the variety of Cretaceous fossils in this display. There are also shark teeth and vertebrae, Inoceramus clams, a small slab containing free-swimming Uintacrinus crinoids, and a plesiosaur flipper. This wing is over 6 feet long. Pteranodons could have a wingspan of up to 25 feet. The fossil was discovered in the Niobrara Chalk in Gove County, Kansas by the Harlan family. They have donated several specimens from their collection to the museum. Other collections in the Cretaceous fossil display are parts of the Walrafen collection and the collections of Robert Taylor, Jack Meyer and A.C.Carpenter.
