Eomysticetus is an extinct genus of toothless baleen whale from the late Oligocene (Chattian) Chandler Bridge Formation of South Carolina.[1]

Physical characteristics[edit]

Eomysticetus is a member of the family Eomysticetidae, which also includes Micromysticetus, Tohoraata, Tokarahia, and Yamatocetus.[2] Like other members of the mysticete clade Chaeomysticeti, its jaws had baleen instead of teeth, meaning that it could filter plankton with its baleen plates.[3][4][5][6]

Unlike modern baleen whales, Eomysticetus had a blowhole that was positioned ahead of the eyes, and the characteristics of its vertebrae and flipper bones are akin to those of archaeocetes like Basilosaurus.[3]

Taxonomy[edit]

There are two species of Eomysticetus, E. whitmorei and E. carolinensis, both from the Chandler Bridge Formation of South Carolina.[1]
