Un nuevo dinosaurio terópodo («Prodeinodon»sp.) en el Cretácico Inferior de La Cantalera (Teruel)

Abstract

We describe four theropod teeth from the Upper Hauterivian-Lowermost Barremian of La Cantalera (Teruel, Spain), characterized by the presence of denticles only in their distal edge, being the mesial one rounded. These two features suggest affinities with Velociraptorinae, but also with Compsognathidae and Troodontidae, and so they are assigned to Maniraptora. La Cantalera's teeth resemble the holotypes of Megalosaurus dunkeri Dames, 1884 from the Berriasian of Germany and Prodeinodon mongoliensis Osborn, 1924a from the Hauterivian of Mongolia, and are assigned to "Prodeinodon" sp. Megalosaurus dunkeri has been placed in its own genus, Altispinax, but this name is normally used for three articulated dorsal vertebrae from the Wealden of England. We propose the name "Prodeinodon" dunkeri (Dames, 1884) n. comb, for the German Megalosaurus. "Prodeinodon" is only known by isolated teeth and is classified as Maniraptora incertae sedis
