The stegosaurus was pretty cool. Some of the tail spikes seemed bigger than the head.
The triceratops was pretty sweet too. It was huge!
There is also the fossil of a xiphactinus audax- a huge fish. It is one of only a few complete skeletons found.
There were dinosaur eggs from China, and several other fossils and exhibits.
Another museum on the campus is the Weidner Wildlife Museum. We got lucky and arrived when it was still open. It's not open as much as the natural history museum (see hours below).
There were numerous stuffed heads of animals from around the world. Many were North American big game.
