Hypsibema is a Hadrosauroid (potentially Hadrosaurid) that is mainly famous because it is the state fossil of Missouri, a state where fossils are certainly few and far between, as Hypsibema is based on very fragmentary and partial material. It, like many early described dinosaur genera, has two species for some reason. H. missouriensis was found in Bollinger County, Missouri, specifically the Ripley Formation; where as H. crassicauda was found in North Carolina. They lived in the Campanian age of the Late Cretaceous, approximately between 83 and 72 million years ago. Bothare only based off of some vertebrae.
