A study in 2014 suggested that ''[[Hallucigenia]]'' are stem-group onychophorans based on their claws, which have overlapped internal structures resembling those of an extant onychophoran.<ref name="ReferenceA" /> This interpretation was questioned by later studies, as the structures may be a [[panarthropod]] plesiomorphy.<ref name=":11" /><ref name=":28" />
