"Halitherium" was an early
sea cowthat started in the late Eocene, then the Oligocene. Its fossils are common in European shales. Inside its flippers were finger bones that did not stick out. "Halitherium" also had very poorly developed back legs. Therefore, it had no external hind legs. It did, however, have a basic femur, joined to a reduced pelvis. "Halitherium" also had elongated ribsto increase lungcapacity to provide fine control of buoyancy.
