Labocania

Molnar 1974

Labocania is an extinct genus of theropod dinosaur of disputed affinities, known from the Late Cretaceous of Mexico. Initially regarded as an indeterminate theropod, later studies have mentioned possible affinities with tyrannosaurids, abelisaurids, or carcharodontosaurids. More recent research based on additional fossil material found support for a position within the tyrannosaurine clade Teratophoneini. Two species have been proposed: L. anomala, likely from the La Bocana Roja Formation, and L. aguillonae from the Cerro del Pueblo Formation.
