Diet: Carnivore/Piscivore.
Size: Roughly about‭ ‬2.5‭ ‬meters long.
Known locations: Germany‭ ‬-‭ ‬Hassberge Formation.‭ ‬Poland‭ ‬-Drawno Beds Formation.‭ ‬USA,‭ ‬Arizona‭ ‬-‭ ‬Chinle Formation,‭ ‬Texas‭ ‬-‭ ‬Colorado City Formation,‭ ‬Tecovas Formation,‭ ‬and Wyoming‭ ‬-‭ ‬Popo Agie Formation.
Time period: Carnian of the Triassic.
Fossil representation: Numerous individuals,‭ ‬though often of partial remains.

       Paleorhinus has been one of the key phytosaur genera for well over a hundred years now,‭ ‬however many of the species once assigned to‭ ‬the genus have now been re-assigned to other genera.‭ ‬At the time of writing the only recognised species of Paleorhinus are the type species P.‭ ‬bransoni from the USA,‭ ‬and P.‭ ‬angustifrons and P.‭ ‬cf.‭ ‬arenaceus from Germany and Poland respectively.
       Like all phytosaurs,‭ ‬Paleorhinus was not related to crocodiles,‭ ‬yet would have been very much like a modern crocodile in overall appearance and ecological niche.‭ ‬Though Paleorhinus would have rested on land,‭ ‬most hunting would have been done in the water.
