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.
