Named By: S. W. Williston - 1904.
Synonyms: Francosuchus angustifrons, Paleorhinus parvus.
Classification: Chordata, Reptilia, Crurotarsi, Phytosauria.
Species: P. bransoni (type), P. angustifrons, P. cf. arenaceus.
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.
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.
