       Phyllodontosuchus is a genus of sphenosuchian crocodile that lived in Asia during the early Jurassic.‭ ‬Phyllodontosuchus had a heterodont dentition,‭ ‬meaning that the shape of the teeth differed according to their position in the mouth.‭ ‬The first few teeth in the mouth were conical in a similar fashion to most other crocodylomorphs,‭ ‬but the teeth behind these were more leaf shaped.‭
       It may be that Phyllodontosuchus was in the process of switching from a carnivorous meat eating diet,‭ ‬to a herbivorous plant eating diet.‭ ‬This is backed up by the observation that some sauropodomorph and ornithischian dinosaurs which ate plants had similar tooth arrangements,‭ ‬though they are not a close match when studied in detail.‭ ‬It is also noted some other genera of sphenosuchian crocodylomorphs are also identified as eating plants,‭ ‬therefore the probability is that Phyllodontosuchus was at least capable of being omnivorous‭ (‬eating meat and plants‭) ‬while potentially completely herbivorous.‭
       At the time of its description‭ (‬and writing of this article‭) ‬Phyllodontosuchus is known only from a partially crushed skull and jaws.‭ ‬These seem to come from an adult individual,‭ ‬and with a length of just over seven centimetres,‭ ‬it would seem that Phyllodontosuchus was a small crocodylomorph.
