       The name Libycosaurus is definitely a misnomer to be sure.‭ ‬When Libycosaurus was first named by Bonarelli in‭ ‬1947‭ ‬the partial fossil remains were thought to be those of a dinosaur.‭ ‬It was only later that it was realised that Libycosaurus was actually a kind of prehistoric relative of hippopotamuses.‭ ‬At the time of writing Libycosaurus is known from three species,‭ ‬L.‭ ‬algeriensis however is only known from teeth,‭ ‬and for this reason this species of Libycosaurus is often treated as dubious.
       Libycosaurus is not the only mammal to have been mistaken for a reptile.‭ ‬Basilosaurus for example means‭ ‘‬king lizard‭’‬,‭ ‬even though Basilosaurus is actually a whale.
