Aetonyx (/ˈiːtənɨks/ meaning “eagle claw”, referring to its claws, which were like those of an eagle (Greek αετος/aëtos = eagle + ονυξ/onyx = claw) is a genus of Early Jurassic sauropodomorph dinosaur which lived around 198 million years ago during the Hettangian stage in South Africa.
Taxonomy
Broom (1911) classified Aetonyx as a carnosaur, which was followed by von Huene (1932) (who placed Aetonyx in a distinct family Gryponychidae along with Gryponyx),[1][2] but Aetonyx was eventually recognized as a sauropodomorph by van Hoepen (1920) and Nopcsa (1928).[3][4] Numerous authors either classified as an anchisaurid or placed it in synonymy with Massospondylus,[4][5][6] but Galton and Upchurch (2004) tabulated it as a dubious sauropodomorph in their list of basal sauropodomorphs.[7]
