The First Southern Hemisphere Occurrence of the Extinct Cretaceous Sclerorhynchoid Sawfish Ptychotrygon (Chondrichthyes, Batoidea), With a Review of Ptychotrygon Taxonomy

A new extinct sclerorhynchoid sawfish, Ptychotrygon ameghinorum sp. nov., is presented here based on abundant isolated teeth and some dermal denticles, which were recovered from the Mata Amarilla Formation, belonging to the lower Upper Cretaceous of the Santa Cruz Province in the Austral Basin of Pa...
