Aetonyx

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 with Massospondylus, a prosauropod. Aetonyx is now, therefore, an invalid name.

Before the confusion was clarified, the type species was recorded as A. palustris. It was named by Robert Broom (1866 - 1951), South African palaeontologist, in 1911. The fossil was found in South Africa.
