The oldest "toothed" baleen whale (Mysticeti: Aetiocetidae) in the Northern Hemisphere ...
The origin and early evolution of baleen whales (Mysticeti, the largest extant vertebrates) have been linked to the inception of the Antarctic Circumpolar Current (ACC) at the Eocene-Oligocene boundary, and the only described Eocene mysticetes were found in the Southern Hemisphere (Antarctica, Peru)...
