Description
Original diagnosis after Boulemia & Adnet, 2023 [32308]: Large fossil species of Physogaleus sharing the classicdisjunctive monognathic heterodonty with anterior teeth showinga sigmoid and twisted cusp and lateral teeth having a distally bentcusp and a serrated distal heel. This species is characterized by theteeth having cusps peculiarly low and a thickening of the overlap-ping labiobasal border of crown, which become a saliant roundedtransversal bulge in lower teeth. By this it is distinguished from allother fossil species of Physogaleus
