Malefica

Malefica (meaning "witch" or "sorceress") is a genus of hadrosaurid dinosaur from the Late Cretaceous (Campanian) Aguja Formation of Texas. The type and only species is Malefica deckerti.

== Discovery and naming == The holotype of Malefica, TxVP 41917-1, is a partial left maxilla recovered from Bruja Canyon in Big Bend National Park. In 2002, it was assigned to the genus Kritosaurus, as cf. K. navajovius. Twenty years later, it was discovered to contain a number of useful diagnostic traits that allow it to be described as a new taxon, despite being fragmentary. The generic name, "Malefica", means "witch" or "sorceress" in Latin, referring to its discovery in Bruja Canyon (bruja being Spanish for "witch"). The specific name, "deckerti", honors Frank Deckert, the specimen's discoverer and former superintendent of Big Bend National Park.
