Four cranial metrics for OH 83 and 33 other Middle and Late Pleistocene <em>Homo</em> fossils

This brief dataset presents the four cranial metrics that are measurable for the OH 83 partial cranium (a Middle Pleistocene Homo sapiens fossil from Olduvai Gorge, Tanzania) alongside the same four metrics for 33 other Middle and Late Pleistocene Homo crania. This comparative dataset extends the original comparative data presented in Reiner et al. (2017)'s initial description of OH 83.
