Abstract: The claws of the Cambrian lobopodian Hallucigenia resemble the claws and jaws of extant onychophorans, establishing a close relationship between hallucigeniid lobopodians and onychophorans, resolving tardigrades as the closest extant relatives of true arthropods, and showing that the earliest ancestor of the arthropods and their kin would have looked like a lobopodian.
