Basilosaurus
Basilosaurus (order Cetacea, suborder Archaeoceti) One of the best-known archaeocetes; it grew to approximately 20 m in length and lived during the Upper Eocene. It was discovered recently that Basilosaurus retained small hind limbs, useless for locomotion, but perhaps usable as claspers during copulation.
