Aristosaurus is not a true dinosaur — it is a prosauropod-grade archosaur or early reptile from the Early Triassic of South Africa, predating the dinosaur radiation. It is generally regarded as a nomen dubium, as the material is fragmentary and its taxonomic status is uncertain. Some authorities have considered it possibly synonymous with Euskelosaurus or related forms, but no firm synonymy has been established. It should not be confused with later, well-known dinosaur genera.
