Aetonyx (meaning “eagle claw”, referring to its claws, which were like those of an eagle (Greek αετος/aëtos = eagle + ονυξ/onyx = claw) was the name given to the fossilized remains of Early Jurassic dinosaur which lived around 198 million years ago during the Hettangian stage.

It used to be classified as a carnosaur, but has since been identified as a prosauropod. Aetonyx is now, therefore, a sauropodomorph. It is a Junior synonym of Massospondylus.
