Phyllodontosuchus (Ancient Greek, meaning "leaf tooth crocodile", in reference to the shape of the middle and posterior teeth) is a genus of sphenosuchian, a type of basal crocodylomorph, the clade that comprises the crocodilians and their closest kin. It is known from a skull and jaws from Lower Jurassic rocks of Yunnan, China. Phyllodontosuchus is unusual because some of its teeth were leaf-shaped, like those of some herbivorous dinosaurs, and it does not appear to have been a strict carnivore like most other crocodylomorphs.
