Heterodontosauridae ("different-toothed lizards") is a family of early ornithischian dinosaurs that have often been considered basal ornithopods, although recent studies suggest they may have been more closely related to marginocephalians. Although their fossils are rare, they lived around the globe beginning in the Late Triassic Period and may have persisted into the Cretaceous.

- Heterodontosauridae ("different-toothed lizards") is a family of early ornithischian dinosaurs that were likely among the most basal (primitive) members of the group. Although their fossils are rare, they lived around the globe beginning in the Early Jurassic Period, and a few late-surviving species persisted into the Early Cretaceous.

abstract
| - Heterodontosauridae ("different-toothed lizards") is a family of early ornithischian dinosaurs that have often been considered basal ornithopods, although recent studies suggest they may have been more closely related to marginocephalians. Although their fossils are rare, they lived around the globe beginning in the Late Triassic Period and may have persisted into the Cretaceous. Heterodontosaurids were small dinosaurs, less than 3 meters (10 feet) in length. They are known mainly for their characteristic teeth, including enlarged canine-like tusks and cheek teeth adapted for chewing, analogous to those of Cretaceous hadrosaurs. Their diet was herbivorous or possibly omnivorous.

Although their fossils are rare, they lived around the globe beginning in the Early Jurassic Period, and a few late-surviving species persisted into the Early Cretaceous. Heterodontosaurids were fox-sized dinosaurs less than 2 meters (6.6 ft) in length, including a long tail. They are known mainly for their characteristic teeth, including enlarged canine-like tusks and cheek teeth adapted for chewing, analogous to those of Cretaceous hadrosaurids. Their diet was herbivorous or possibly omnivorous.
