Basilosauridae is a family of extinct cetaceans. They lived during the middle to the early late Eocene and are known from all continents, including Antarctica.[1][2] They were probably the first fully aquatic cetaceans.[3][4] The group is noted to be a paraphyletic assemblage of stem group whales[5] from which the monophyletic Neoceti are derived.[6]
