Enigmacursor is known from a single, unusually complete skeleton, but the skull is still missing.1

Its closest relative is Yandusaurus hongheensis, a dinosaur from the Late Jurassic of China.3

The name 'Enigmacursor' means 'puzzling runner' because scientists were confused for a long time about small plant-eaters from the Morrison Formation.1

It lived between 152 and 145 million years ago, during the Late Jurassic Period.1

Enigmacursor was a neornithischian dinosaur, a group of beaked, plant-eating ornithischians.2

Chatschader da mitus

Mitus: Many small dinosaur fossils from the Morrison Formation were thought to be different species like Nanosaurus, Laosaurus and Drinker.

Vardad: Scientists now think those fossils are not distinct enough to name, and only Enigmacursor is a valid species.1
