Tritylodontidae ("three-knob teeth", named after the shape of their cheek teeth) is an extinct family of small to medium-sized, highly specialized mammal-like cynodonts, with several mammalian traits including erect limbs, endothermy and details of the skeleton.[1] They were the last-known family of the non-mammaliaform synapsids, persisting into the Early Cretaceous.[2]
Most tritylodontids are thought to have been herbivorous, feeding on vegetation such as stems, leaves, and roots, although at least one may have had a more omnivorous diet.[3] Tritylodontid fossils are found in the Americas, South Africa, and Eurasia—they appear to have had an almost global distribution, including Antarctica.[4]
