In Depth

       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.
