Teleidosaurus
is a genus of primitive form thalatosuchian marine
crocodile.
Originally named as a species of Teleosaurus,
Teleidosaurus was
established as a distinct genus in 1869, and was considered to
possibly be one of the oldest marine crocodiles until 2015 when the
genus Zoneait
was named. As a metriorhynchoid, Teleidosaurus
would
have been a marine crocodile, actively hunting in shallow sea
waters, though the genus was still considerably more primitive than
actual metriorhynchids which evolved much better adaptations for open
ocean life.
Two
former species of Teleidosaurus, T.
bathonicus and T. gaudryi
have been used to create the genus Eoneustes.
In addition one
remaining species, T. joberti, has been
considered by some to be
synonymous with the type species T. calvadosii,
though some authors
continue to separate them at the time of writing.
