Abstract
Endocasts provide the only direct evidence of brain morphology in hominin fossils. In this study, I used computed tomography data, biomedical image processing and geometric morphometrics to generate, reconstruct and investigate a digital endocast of the Late Pleistocene human individual from Hofmeyr, South Africa. Its estimated endocranial volume based on multiple reconstructions is 1,541 ± 10 ml. Impressions of brain convolutions reveal a modern human pattern of sulci and gyri including those in several brain regions that are associated with language functions. Several imprints of meningeal vessels are also preserved. The globular endocranial shape of the Hofmeyr individual conforms to the shape variation of present-day humans with morphometric affinities to Upper Paleolithic Eurasian fossils as well as present-day (southern) Africans.
