The “premodern” skull was found in the Paracas region of Perú. It does not necessarily mean that they are related. There is some possibility that the “premodern” is in fact a precursor of the “conehead” type, but since we do not have any dating analysis at hand, we may only speculate in this regard.
The “conehead” type is very unusual because of the cranial shape. Here we have three specimens, which exclude the possibility of random or artificial deformation (the already mentioned Nubian deformations had quite a number of individual variations). They have individual characteristics within the range of overall morphology. There is no doubt that they are closely related and possibly represent quite a distinct branch of the genus Homo, if not an entirely different species.
