The pattern of migration out of Africa and into Eurasia remains one of the most important considerations in the evolution of humans. Questions remain about the timing of this flux, the geographic routes taken and recent paleogenomic findings have greatly complicated this picture. Azokh Cave is located in the southern Caucasus on one of the possible migratory routes from Africa into Eurasia, and is strategically placed geographically to address some of these issues. It contains a long sedimentary succession dating to at least Middle Pleistocene times and excavations to date have shown occupation by at least three different species of hominin.
Excavations by a previous team in the main entrance passage to the cave system produced a rich faunal assemblage, Acheulian and Mousterian lithic artifacts, and hominin remains ascribable to Homo heidelbergensis. A new phase of systematic excavation was initiated at the site in 2002, which has produced further faunal remains, pre-Mousterian and Mousterian artifacts, and identified two additional entrance passages containing undisturbed sediments.
Significantly, the renewed phase of excavation at Azokh Cave has, for the first time, produced Upper Pleistocene hominin remains from the site. This find, a maxillary left first permanent molar tooth, was recovered from deposits dated c. 100 ka in the rear of the main entrance passage. The morphology, metrics and taurodontism present in this specimen are characteristic of Neandertal upper first molars. Crown dimensions and root robusticity are comparable to mean values for Neandertal upper first molars from the similarly dated site of Krapina, Croatia.
