Paleoneurology of an early Neandertal: endocranial size, shape, and features of Saccopastore 1

The Saccopastore 1 cranium was found near Rome in 1929, and its most probable age is about 120 ka (OIS 5e). The Neandertal morphology of the specimen was recognized just after the discovery by the Italian anthropologist S. Sergi, and subsequently confirmed by several authors. The present paper provides a complete description and analysis of the endocranial shape and features of this specimen, considering anatomical traits, metrics, and landmark data. The main endocranial diameters and the vascular traces resemble the morphology displayed by Middle Pleistocene humans, although lacking some traits described in the European samples referred to as ante-Neandertals. Nevertheless, proportions and endocranial shape support a definite Neandertal morphology, mostly taking into account the lateral development of the frontal lobes and the shape of the parietal areas. Therefore, it may be hypothesized that the Neandertal neurocranial architecture was present since at least OIS 5, as already suggested on the basis of ectocranial morphology. (C) 2007 Elsevier Ltd.
