whitmorei Sanders and Barnes, 2002 (type) Eomysticetus is an extinct genus of baleen whale from the late Oligocene (Chattian) Chandler Bridge Formation of South Carolina.

[1] Eomysticetus is a member of the family Eomysticetidae, which also includes Micromysticetus, Tohoraata, Tokarahia, and Yamatocetus.

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

[8] Baleen whales, as a group, may be sensitive to low-frequency sounds.

[9] 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.
