Killikaike
The genus includes one species, Killikaike blakei, that lived in Argentina during the Early Miocene.[1] 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 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.
