Megalolamna paradoxodon Shimada, Chandler, Lam, Tanaka and Ward, 2016

Tooth type: Anterior teeth tearing or grasping type, lateral teeth cutting type (Shimada et al. 2016).

In 2016, Shimada et al. designated this new species and genus for teeth from the early Miocene (Aquitanian–Burdigalian) of Japan, Peru and the USA (see Shimada et al. 2016: fig. 2). Pfeil (1991: 200, pl. 2, fig. 8) mentioned and illustrated a tooth from Messkirch-Walbertsweiler as Lamna sp. When comparing the illustration of “ Lamna sp. ” with the ones of Megalolamna paradoxodon , it became obvious that it belongs to the latter as per the tooth shape and inclination and position of the lateral cusplets. Shimada et al. (2016) assumed bony fishes as prey for this species.
