is another one of the phytosaurs, reptiles that have a striking
similarity to modern crocodiles, although the position of the
nostrils higher up the snout and in front of the eyes is a dead
giveaway that Nicrosaurus is a phytosaur
(crocodiles have their
nostrils on the tips of their snouts). Nicrosaurus
considered to be closely related to the phytosaur Mystriosuchus,
at one time these two phytosaurs were once thought to represent male
and female versions of phytosaurs in general. This idea came about
upon the basis that the larger snouts of phytosaurs like Nicrosaurus
were display devices only upon 'males’ and were for ‘females’
that had slender gracile snouts like those seen in Mystriosuchus.
little bit of detective work by palaeontologists has since completely
discredited this theory however as the ‘female’ and ‘male’
forms are not only found separate, but are each found in strata that
are from different geological periods. These are the hallmarks of
different genera and species, not sexes.
An interesting discovery regarding a collection of Plateosaurus has found that some of these dinosaurs were possibly trapped in quicksand and then scavenged by wandering predators. Some of the teeth associated with this discovery were found to be those of Nicrosaurus which shows that scavenging was a part of this phytosaurs behaviour. It also brings into light the possibility of Nicrosaurus hunting and killing smaller dinosaurs that would have steadily been becoming much more common towards the end of the Triassic.
