Two xls (Microsoft Excel Worksheet) documents, linked bellow, include 3190 craniological measurements of 18 living worldwide local populations and 524 museum specimens. It is interesting to compare skulls from prehistoric burials (Grimaldi, Cro-Magnon I, Afalou bou Rummel, Predmost III, Chancelade, Erteboelle...) with modern ones.
