Hypsibema is an extinct genus of very large basal hadrosauroid dinosaur from the Late Cretaceous (Campanian) of eastern North America. The type species is H. crassicauda, with a potential second species in H. missouriensis (now generally placed in its own genus, Parrosaurus). Most remains of H. crassicauda, including the type specimen, are known from the Tar Heel Formation of North Carolina, in addition to some remains known from the Marshalltown Formation of New Jersey.[1]
