DENTAL REMAINS FROM THE MIDDLE PALEOLITHIC LAYERS OF ALTAI SITES*

Two Middle Paleolithic cave sites in the Altai – Okladnikov and Chagyrskaya – have yielded dental remains (mostly isolated teeth) of individuals of various ages. A newly discovered mandibular fragment with teeth from Chagyrskaya Cave reveals a trait combination: anterior fossa and epicristid (midtrigonid crest) on molars, metaconid and crest on premolars. The totality of dental traits support the conclusion previously drawn on the basis of postcranial characters: Altai appear to be intermediate between other Eurasian Neanderthals and anatomically modern humans. Keywords: Human evolution, Neanderthals, Mousterians, Gorny Altai, dental traits.

Introduction The lithic industry discovered at the site differs from other industries of the Altai and Siberia by a habitation horizons associated with predominance of butchering tools apparently used Neanderthals were discovered in Okladnikov and to process the carcasses of large animals. Evidently Chagyrskaya in the piedmont zone of the this was a Mousterian hunting and butchering camp northwestern Altai. Okladnikov Cave (formerly site (Derevianko, Markin, 1992).

Like Asian Neanderthals (Turner, 1990). the Okladnikov assemblage, that of Chagyrskaya was The same dental remains were revisited by described as Mousteroid (Derevianko, Markin, Zykin, E.G. Shpakova, in whose view, they differ from 2009; Derevianko, Markin, 2012; Markin, Zykin, contemporaneous remains from Zykina, 2011; Derevianko, Markin, 2011). These two in being less archaic. Shpakova concluded that in cave sites strongly suggest that Neanderthals were certain respects the teeth from Okladnikov Cave present in the Altai. resemble those of European Upper Paleolithic humans Among the ¿ rst dental remains from Chagyrskaya (Shpakova, 2000, 2001; Shpakova, Derevianko, was a specimen that we identified as a lower 2000).

Also, the crown dimensions of the preserved teeth tradition was introduced by the Neanderthal migrants are similar to those of Upper Paleolithic Europeans. to the Altai. Based on these observations, Shpakova concludes that B.T. Viola, who studied two permanent teeth from the Okladnikov Cave hominins were anatomically Chagyrskaya, attributed them to Neanderthals, their modern humans (Shpakova, Derevianko, 2000; poor preservation and heavy wear notwithstanding Shpakova, 2001).

Like his predecessors, and a canine, two premolars, M1 and M2 (Viola 2012). he noted that interpreting the observations was Despite a moderate abrasion, it was possible to detect difficult. On the one hand, archaic (specifically anterior fossae and epicristids (midtrigonid crests) on Neanderthal) features are no doubt present. These both molars, and metaconids and crests on premolars – include the wrinkled occlusal surface of the lower features typical of Neanderthals. molar, complexity of furrows, a distinct anterior fossa, and a sixth cusp. On the other hand, the ¿ rst molar lacks the epicristid (Zubov, 1992), or midtrigonid Materials and methods crest, which is a characteristically Neanderthal trait – 96 %, according to Bailey (2002). The third molar Thanks to ongoing excavations at Chagyrskaya, the of another individual from the same cave exhibits number of dental remains increased markedly. In this an incomplete crest, indirectly suggesting that the study, dental remains discovered by S.V. Markin in epicristid was present.

Referring to Bailey’s The preservation of several deciduous and summary (2001), Viola concludes that continuous permanent teeth from the Sibiryachikha layers of midtrigonid crests on the occlusal surface are Chagyrskaya has enabled us to take standard dental exceedingly rare in modern humans but very common measurements according to the technique used by in Neanderthals (2009: 133).
