Taxonomy and description
editTwo species are recognized, E. langewieschei and E. latirostris. The latter was originally described as a subspecies of Squalodon bariensis, S. b. latirostris, but is distinct from S. bariensis. Eosqualodon can be distinguished from Squalodon in having a broader rostral base, the caudal border of the external nares (blowhole) at the height of the caudal part of the orbits, and weakly developed intertemporal construction.[1][2]
