Palaeopathology of the Pleistocene specimen D2600 from Dmanisi (Republic of Georgia)

Here we present a detailed palaeopathological study of the hominin mandible D2600 recov-ered at the Dmanisi site, Republic of Georgia. The Dmanisi assemblage represents theearliest evidence of hominins outside Africa with an age of 1.8 Ma. D2600 is the holotypeof Homo georgicus species and its taxon...
