Eosqualodon

Eosqualodon is an extinct genus of squalodontid odontocete from the Late Oligocene to Early Miocene of northwestern Germany and northeastern Italy.

Taxonomy and description

Two species E. langewieschei and E. latirostris, have traditionally been recognised, but recent phylogenetic analysis has found the latter to not be the sister taxon to the former, thus suggesting the genus Eosqualodon is monotypic. 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 at the height of the caudal part of the orbits, and weakly developed intertemporal construction.
