Mammal, Whale
The squalodont whales of the Oligocene and Miocene were fully-aquatic yet primitive because they still had heterodont teeth reminiscent of their land-based Eocene ancestors. Their teeth still had the general form of incisors/canines and premolars/molars but were following a trend toward homodonty as seen in modern toothed whales (odontocetes). They died out by the end of the Miocene.
