The oldest mysticete in the Northern Hemisphere ...
Extant baleen whales (Mysticeti) use the characteristic keratinous baleen for filter-feeding without functional dentition, but the fossil record clearly shows that “toothed” baleen whales have been around since the late Eocene.1 Globally, only two Eocene mysticetes have been found, and both are from...
