Heterodontosaurid

A heterodontosaurid is a type of dinosaur that belonged to the family Heterodontosauridae.
They were small, herbivorous or omnivorous animals that had different types of teeth, including tusks and cheek teeth for chewing.
They lived during the Early Jurassic to the Early Cretaceous periods, about 200 to 140 million years ago.
They are considered to be one of the most primitive groups of ornithischian dinosaurs, which are the group that includes stegosaurs, ankylosaurs, ceratopsians, and hadrosaurs.
Heterodontosaurids have been found on all continents except Australia and Antarctica.
The most well-known heterodontosaurid is Heterodontosaurus, which was named in 1962 from a skull found in South Africa.

A different toothed lizard from the ancient past
With a long and slender tail and a body built to last
You had a beak and tusks and cheek teeth for your food
You were omnivorous, eating plants and meat as your mood

You lived in South Africa, where the sun was bright and warm
You shared your land with other kinds, but you had your own charm
You were small and agile, running on your hind legs
You had five fingers on each hand, with which you could beg

You were a heterodontosaurid, a basal ornithischian
You had large eyes and a narrow skull, you were quite a vision
You were the eponymous member of your family tree
You were Heterodontosaurus, and you fascinate me
