Abstract. The article describes results of using a medical intraoral scanner Medit i500 to obtain odontological information in a course of the survey of the modern population in the western regions of the Republic of Tuva within the framework of the complex ethnographic and anthropological expedition of TuvSU-CPI under the leadership of E.V. Aiyzhi. The experience of using this scanner occurred to be very successful. From a technical point of view, the scanner demonstrated high efficiency and productivity due to the high scanning speed. The use of an intraoral scanner opens up wide methodological possibilities in conducting dental anthropology studies: first, the use of digital images for further analysis instead of wax prints, makes it possible to expand the research program by including a number of features of both the lingual and vestibular surfaces of the crowns, and the occlusive one. Secondly, the researcher has the opportunity to accurately fix the sequence and degree of teething of the permanent change, which is very important for determining the correspondence of the "dental" and passport age in children, which ultimately makes it possible to assess the processes of growth and development in the population. Thirdly, it allows us to study in more detail the morphology of the teeth, more accurately assess the severity score of the dental anthropology feature. In addition, thanks to the use of the scanner, we were able to carry out an important methodological study on the analysis of interobserver agreement in the assessment of some dental traits.

Introduction. Russian-Indian Anthropological expedition was organized in 2019 by Paleoethnology Research Center (Russia), Timiryazev State Museum of Biology (Russia) and Department of Anthropology University of Calcutta (India). The goal was to examine the peoples of Tripura state, North-East India. Data and methods. About 350 individuals from eight different locations next to Agartala were examined. Currently there are 19 tribes in Tripura, Tripuri being one of them. The most common Tripuri’s surname is Debbarma. During the research 254 Debbarmas were examined, among them 106 individuals were children and teenagers (58 male and 48 female), and 148 individuals were older than 17 years (76 male and 72 female). The Russian-Indian Anthropological expedition research consisted of a complex study of Tripuri including morphology of body, head and face, dermatoglyphics, and dental anthropology. Social questionnaire and anthropological photo were also obligatory. All data was hold according to bioethics and the Privacy law. For further examination the data was depersonificated. Results. During the survey, basic information about the individual, including tribal affiliation, was clarified. An extended questionnaire made it possible to study many aspects of social relationships and build a population-genetic network. According to somatometric characteristics, tripuri males from the Debbarma family have an average body length (162.1 cm), relatively broad shoulders and an average pelvic width. A cephalometric study of 19 features was carried out. The studied group can be characterized as brachycephalic, leptoprosopic according to the morphological facial index and mesorrhine according to the nasal index. The zygomatic diameter is large, and the mandibular diameter is above average (on the Indian scale of variability). A detailed fixation of cephaloscopic features in children and adults was carried out, which made it possible to describe tripuri as representatives of a large Asian-American branch (race) of humanity. According to the odontological program, 293 people were examined, 221 of which were tripuri. Anthropological photo-fixation was carried out, and based on these materials the first composite tripuri portraits were compiled, published in this article. Conclusion. In the second season of the Russian-Indian anthropological expedition, data were collected on one of the insufficiently studied peoples of Northeast India – the Tripuri tribe. The group was investigated according to the maximum number of anthropological methods available in the field. For the first time, somatometric, cephalometric and cephaloscopic materials have been obtained and preliminary presented.

Introduction. The article for the first time presents the results of the analysis of the cephaloscopic features of the Amur Evenks examined during the Amur Anthropological expedition in 2015 and 2016. The aim of the study is to characterize the Amur Evenks according to the program of descriptive features of the face and head and to consider them on the scale of cephaloscopic variability of the continental branch of the Asian–American race. Material and methods. Amur Evenks (men and women, N=83) were studied according to the classical cephaloscopic program, which included 32 descriptive signs. Most of the signs were determined by anthropological photographs. The expedition recorded the pigmentation of the skin and eyes, the color and shape of the hair, the degree of development of epicanthus. Empirical methods were used (counting the frequencies of feature scores and calculating their averages) and statistical methods (betweengroup analysis and plotting multidimensional scaling using special programs STATISTICA 8.0 and PAST). Results. Amur Evenks are characterized by dark pigmented hair and eyes, a fairly light skin tone. The hair on the head is straight and stiff. Beard growth is weak, eyebrows – average. The face is strongly flattened, with a strong or medium protrusion of the cheekbones and a weakly developed chin. The eye slit is of small width with an oblique internal slope. Epicanthus is either absent or poorly developed, the fold of the upper eyelid is strongly developed. The nose profile is concave. The upper lip is medium-high, proheilic. Compared with other Tunguska groups, Amur Evenks are characterized by darker pigmentation of the eyes, lower frequency of occurrence of epicanthus, a more concave back of the nose, a proheilic upper lip, a relatively high nose bridge, a strong inclination of the forehead and a developed brow. The results of the intergroup multivariate analysis illustrated the greatest convergence of the Amur Evenks with the groups of Central Asia, and with the groups of Northeast Asia, namely with the Yukaghirs and Evens. Conclusion. According to the totality of the cephaloscopic features of the Amur Evenks, they can be attributed to representatives of the Baikal type of the North Asian race, but at the same time, signs of the Katanga anthropological variant can be traced in their morphological type. The probable reason for the rapprochement of the Amur Evenks with the Central Asian samples may be the territorial proximity of the populations of the Amur Evenks to Yakutia, which could cause possible metisation processes between Evenks and Yakuts – representatives of the Central Asian type.

Materials and methods. This article is a collective research conducted by the members of the Nubian archaeological and anthropological expedition of the Research Institute and Museum of Anthropology of the Lomonosov Moscow State University. The article outlines the main results of the expedition's work over four field seasons at the Deraheib site, located at the headstream of Wadi al-Allaqi, in the northern part of the Nubian desert (Central Atbai) in the Republic of Sudan. From 2017 to 2022 The Nubian expedition excavated the Northern Fortress, Building 3 (Mosque) at the settlement of Deraheib, the Southern Necropolis; carried out an reconnaissance mission to the Onib ring structure. Results and discussion. Based on the study of the obtained archaeological materials (primarily the analysis of ceramics and textiles), as well as data from written sources, it was established that the medieval part of history of the monument covers the period between the 9th and 12th centuries. The archaeological site of Deraheib can be associated with the city of Al-Allaqi, mentioned in Arabic sources as a gold mining center in the Nubian desert, a trading city that was located on one of the caravan routes connecting the Red Sea port of Aidhab and the city of Aswan. The materials of the excavations of the Northern Fortress made it possible to advance a hypothesis that the building, erected in the 9th century, functioned more like a fortified castle of the local ruler rather than a fortress. The study of Building 3 allows us to say with confidence that it was a Friday mosque, founded at the beginning of the 10th century. Ongoing excavations in the Southern Necropolis have revealed Muslim burials (25 out of 31 investigated burials) and burials that are associated with the population that lived on the territory of Atbai in the Late Antique — Early Medieval period, known from classical sources as Blemmyes. A group of anthropologists obtained important data on the sex and age of the population of Deraheib, traces of daily activities and pathologies reflected in the skeleton. An important direction in the research of the MSU complex expedition is the study of the modern population of Central Atbai, primarily the Bisharin tribe of the Beja tribal union. The article outlines the main directions of these studies and preliminary results.
