Gobiconodon is an extinct genus of carnivorous mammal from the Middle Jurassic to Early Cretaceous. It weighed 5.4 kilograms (12 lb),[2] had a skull of 10 cm (3.9 in) in length, and had 35 cm (14 in) in presacral body length.[3] It was one of the largest mammals known from the Mesozoic.[4] Like other gobiconodontids, it possesses several speciations towards carnivory, such as shearing molar teeth, large canine-like incisors and powerful jaw and forelimb musculature, indicating that it probably fed on vertebrate prey; rather uniquely among predatory mammals and other eutriconodonts, the lower canines were vestigial, with the first lower incisor pair having become massive and canine-like. Like the larger Repenomamus there might be some evidence of scavenging.[5]
