Hypsibema missouriense is a type of dinosaur called a Hadrosaur or “duck-billed” dinosaur. It was a herbivore with jaws that contained over 1,000 teeth. Hypsibema had evolved specialized teeth to handle the tough, fibrous vegetation of the time. This dinosaur lived in Missouri during the Late Cretaceous Period. Hypsibema was first discovered in 1942 by Dan Stewart, near the town of Glen Allen, MO, and became the state’s official dinosaur on July 9, 2004 (RsMo 10.095) A reconstruction of Missouri’s State Dinosaur can be seen at the Bollinger Museum of Natural History in Marble Hill, MO.
