 Eutriconodonts possess several speciations towards animalivory, and the larger forms such as "Repenomamus", "Gobiconodon" and "Jugulator" probably fed on vertebrate prey.Similarly the "tooth lips" of clevosaurid sphenodontians such as "Clevosaurus" are described as "carnassial-like".In modern carnivorans the carnassial teeth pairs are found on either side of the jaw and are composed of the fourth upper pre-molar and the first lower molar (P4/m1).
