Genus: Fodonyx HONE & BENTON, 2008
Etymology: The new generic name Fodonyx is modelled on the name Scaphonyx, given to the Brazilian rhynchosaur by Woodward (1907), and meaning "spade claw," Latin, fodere, "to dig" and Greek, onyx, "claw"; hence meaning 'digging claw', in reference to the large unguals present on the foot.
