"Large saber canine [teeth] are unexpected in a herbivore," wrote the authors of the study that describes the new anomodont, a member of the therapsid group (which produced some lines that eventually led to mammals).
And these fangs weren't subtle. The saber teeth were more than half the length of the animal's 22.5-centimeter-long skull—proportionally bigger even than those of a carnivorous contemporary, the Inostrancevia.
