The university's Sternberg Museum of Natural History features interactive natural science exhibitions, many traveling and temporary exhibitions, an acclaimed Discovery Room, and a Museum Store. The museum houses over 100,000 square feet (10,000 m2) of dinosaurs, fossils, prehistoric animals, giant sea-swimming lizards and fish that inhabited Kansas over 70-80 million years ago. The Sternberg Museum also includes more than 3.7 million specimens in collections of paleontology, geology, history, archaeology, ethnology, botany, entomology, ichthyology, herpetology, ornithology and mammalogy. One will find that all these major exhibits contain at least one creature/plant named after Sternberg.
