       Nicrosaurus 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 is today considered to be closely related to the phytosaur Mystriosuchus,‭ ‬and 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.‭ ‬A 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.
