Chilesaurus is an extinct genus of herbivorous dinosaur. The type and only known species so far is Chilesaurus diegosuarezi.[1] Chilesaurus lived between 148-147 million years ago (Mya) in the Late Jurassic period of Chile.[2] Showing a combination of traits from theropods, ornithischians, and sauropodomorphs, this genus has far-reaching implications for the evolution of dinosaurs, such as whether the traditional saurischian-ornithischian split is superior or inferior to the proposed group Ornithoscelida.[3]
