Piatnitzkysaurus floresi Bonaparte, 1979

Age . Callovian.

Occurrence. Canadón Asfalto Formation, Chubut, Argentina.

Diagnosis. Basis of the ascending process of the maxilla strongly inflated.

Remarks. Piatnitzkysaurus is based on two associated partial skeletons from the upper Middle Jurassic of Patagonia, described by Bonaparte (1979, 1986). Being the only Middle Jurassic theropod from the Southern Hemisphere known from good skeletal material, it is of great phylogenetic and biogeographic interest.
