Tejedor et al., 2006

Killikaike blakei was collected from the Santa Cruz Formation in the far south of Argentina in January, 2005 and the type specimen consists of a remarkably well preserved face. The neurocranium is not present. The specimen was named for the locality where it was found Killik Aike Norte, on the estate of the Blake family.[1]

Perry et al. (2014) considered K. blakei to be a junior synonym of Homunculus patagonicus, which is also known from the Santa Cruz Formation.[2] However, Silvestro at al. (2017) considered Killikaike to be a distinct genus.[3] Kay & Perry (2019) continued to regard the species as synonymous.[4]
