Manipulonyx is an extinct genus of alvarezsaurid theropod dinosaurs known from the Late Cretaceous (Maastrichtian age) Nemegt Formation of Mongolia. The genus contains a single species, Manipulonyx reshetovi, known from a partial skeleton. This includes the most complete forelimb known from any member of the alvarezsaurid subfamily Parvicursorinae, including all of the proximal bones. Manipulonyx has been interpreted as an ovivore (egg-eater), with unique ossified spikes on the wrist that helped the animal to grasp eggs and an enlarged claw on the functionally-monodactyl hand being used to pun
