Pontobasileus is an archaeocete whale known from a fragment of a single tooth described by Leidy 1873.[1][2] It can questionably be dated to the Eocene of Alabama.[3]

Leidy assigned the tooth to Archaeoceti, but without neither a stratigraphic nor a geographic locality it is virtually impossible to argue for or against this classification. The tooth was later classified as an Archaeoceti incertae sedis[4] and even a squalodont odontocete (a more recent whale), but can also be assigned to Protocetidae.[5]
