Malefica is a hadrosaurid dinosaur from the Late Cretaceous of Texas in the United States. Like other hadrosaurs, Malefica was herbivorous, processing plant matter with their broad beaks and battery of teeth in the back of the mouth. It could grow to around 6 m in length, and weighed about 1 t. The discovery of Malefica helped to understand the distribution of hadrosaurs in Cretaceous North America, as well as evolutionary lineages between basal hadrosaurs and the more derived saurolophids.
