Objective: Herein we introduce a newly recovered partial calvaria, OH 83, from the upper Ndutu

Beds of Olduvai Gorge, Tanzania. We present the geological context of its discovery and a comparative analysis of its morphology, placing OH 83 within the context of our current

understanding of the origins and evolution of Homo sapiens.

Materials and methods: We comparatively assessed the morphology of OH 83 using quantitative

and qualitative data from penecontemporaneous fossils and the W.W. Howells modern human

craniometric dataset.

Results: OH 83 is geologically dated to ca. 60–32 ka. Its morphology is indicative of an early modern human, falling at the low end of the range of variation for post-orbital cranial breadth, the high end of the range for bifrontal breadth, and near average in frontal length.

Discussion: There have been numerous attempts to use cranial anatomy to define the species

Homo sapiens and identify it in the fossil record. These efforts have not met wide agreement by

the scientific community due, in part, to the mosaic patterns of cranial variation represented by

the fossils. The variable, mosaic pattern of trait expression in the crania of Middle and Late Pleistocene fossils implies that morphological modernity did not occur at once. However, OH 83

demonstrates that by ca. 60–32 ka modern humans in Africa included individuals that are at the

fairly small and gracile range of modern human cranial variation.
