ONE OF THE ASPECTS OF THE FORMATION OF THE DENTAL MORPHOLOGY DIVERSITY IN THE MESOLITHIC Khaldeeva Nataliya1 , Vasiliev Sergey1 Department of Anthropology, Biological Faculty, Lomonosov Moscow State University, Moscow, Russia The lower jaw from the Mesolithic burial ground, Samara region, village Sidelkino, “Gora Mayak” (2001 Borutskaya Svetlana2 1 2 year’s excavations, leaded by archaeologist Dmitry Stashenkov) was studied. mandibular teeth remained constant change, including the third molars. <...> The study of the dental morphology features was conducted according to the russian odontological program (Zubov, 2006). <...> Permanent dentition was present completely, including third molars. <...> The description was divided into grades diagnostically signifi cant for determining the evolutionary status of the specimen, its place in the anthropological intraspecifi c differentiation. <...> Among archaic features are the following: continuous edge ridge (med-end) on the left LM1, differentiation of the end, hyd, prd on the left LM3, vestibular position of the hld on the left LM1, tami on the right LM1, tuberculum centrale on the right LM3, retromolar space, index of foramen mentale (62.3% – right side of the mandible). <...> Evolutionary progressive features: shallow intertubercular furrows, left LM2 – smooth occlusal surface without additional elements and +4 pattern, 2end (IV) variant on the left LM3, axial position of hld on the left LM1, poor differentiation of LM1 surface, prd> med, the absence of developed cingulum, index of foramen mentale (54% – left side of the mandible), moderate/weak deep of molars’ furrows, parallel furrows on the hypoconid of the right LM3. “Western” odontological complex expresses in the following features: pattern “x”5 on LM1, 2med (II), 1hyd (IV), type 1 of the 1med/1prd contact, variant T (1prd-2prd/II), enamel extention score 3 on the LM2, absence of dw, dtc, tami, protostylid / and its pit on some molars. <...> Feature of the «Eastern» odontological complex: pattern “+” on the LM1. <...> Thus, the odontological type of the Sidelkino specimen can be defi ned as specifi c to modern humans with a certain level of archaic/dearhaization along with the signifi cant predominance of the evolutionary progressive traits. <...> It belongs to europeoid odontological complex with the manifestation of a single east <...>
