Chagyrskaya Cave:A Middle Paleolithic Site In The Altai

This article presents the results of multidisciplinary studies conducted at Chagyrskaya – an Upper Pleistocene karst cave in the northwestern Altai where Middle Paleolithic stone tools and fossil remains of Neanderthals were found. Taphonomic aspects of the site are addressed, and results of science-based analyses including radiocarbon and paleomagnetic dating are presented. The deposits are similar to loess-like Upper Pleistocene loams of Western Siberia. Among the Middle Paleolithic industries of the Altai, the Chagyrskaya industry is paralleled only by that of Okladnikov (formerly Sibiryachikha) Cave. Both represent a local Middle Paleolithic Mousteroid facies, named Sibiryachikha after the eponymous site.     

The Sibiryachikha Facies of the Middle Paleolithic of the Altai

The Middle Paleolithic industry of the Sibiryachikha facies is described on the basis of two stratified sites in the Altai – Okladnikov Cave (formerly Sibiryachikha) and Chagyrskaya Cave. Stratigrtraphic, environmental, and chronological aspects are discussed. The structure of two cave sites is analyzed. Petrographic properties of raw material are described and the typology and technology of the lithic industry are compared with those of other local Middle Paleolithic traditions. The Sibiryachikha facies of the Altai Middle Paleolithic represented by two sites was clearly associated with a small group of Neanderthals who migrated from western Central Asia. Eventually the Middle Paleolithic industry evolved into a local variant of the Upper Paleolithic.     

Environmental Conditions During the Early Human Settlement of Chagyrskaya Cave (Altai)

The article presents the results of a palynological study conducted at the Middle Paleolithic site of Chagyrskaya Cave (Altai). Sediments containing the technocomplex of the Sibiryachikha facies of the Altai Middle Paleolithic accumulated at the end of MIS 4 which corresponds with the final stage of the Ermakovo glaciation. The results of the palynological analysis indicate that during the period in question, predominantly steppe landscapes existed in dry, cold climate conditions.     

The Neanderthals of Okladnikov Cave Altai: Environment and Diet Based on Isotopic Analysis*

The discovery of a Mousteroid industry in the northwestern Altai represents a major finding in Eurasian Paleolithic studies. Isotopic analyses of bone collagen of late Western European Neanderthals have repeatedly indicated that they were extremely carnivorous. However, no corresponding information was previously available for the Neanderthals of the Altai. With this in mind, an isotopic study was conducted to assess the diet of the Middle Paleolithic inhabitants of Okladnikov Cave. Collagen was extracted from seven well preserved bone samples of adults and children and 13С/12С and 15N/14N ratios were calculated. The δ13С content suggests that all individuals were members of a local trophic chain based on plants of the moderate climatic zone. However, the δ15N content demonstrates that their trophic level was high. These findings suggest that the lifestyle of Neanderthals in the northwestern Altai was similar to that of the late European Neanderthals. Both evidently subsisted by hunting large herbivores.     

An Archaic Human Ulna from Chagyrskaya Cave Altai: Morphology and Taxonomy*

Excavations at the Chagyrskaya Cave site in Gorny Altai have revealed a Mousteroid industry along with fragmented human remains. This study focuses on a left ulna from stratum 6a. Its size, proportions, symptoms of disease, and indicators of muscular activity, point to Neanderthal affinities. The bone is large, linking the individual with certain Near Eastern Neanderthal males such as Shanidar. Symptoms of what might be diagnosed as Forestier disease suggest likewise.

Non-dietary Marks in the Anterior Dentition of the Krapina Neanderthals

A sample of 82 anterior teeth from Krapina (Croatia) was studied using a light binocular microscope and a scanning electron microscope to document the presence of non-dietary dental scratches. The patterns of distribution, location and orientation of these marks suggest two different aetiologies: scratches on the labial-occlusal enamel border appear to be related to the action of clenching abrasive materials between teeth, while the scratches primarily in the centre of the labial face correspond to cutmarks as described by other researchers. These scratches may have been produced when flake tools involved in processing materials held between the anterior teeth came into contact with the labial enamel face. Alternatively, they may simply reflect some consistent operation which pulled hard objects across the labial surfaces of the anterior teeth. In either case, the marks on the central face of the labial surface provide evidence for manual dexterity in the Neanderthals. Of the seven Krapina individuals which show a predominant pattern, one shows a pattern of left oblique marks, while six provide evidence of right-handedness. Coupled with other Neanderthal or Upper Pleistocene individuals with these patterns, right-handedness is the dominant pattern in 90 per cent of the documented cases. One complicating factor in the analysis of these scratches in the Krapina hominids is that marks of a similar morphology are found in several anterior teeth of Ursus spelaeus from the site. While resembling the marks on the hominid incisors, the scratches on the bears lack a dominant orientation on the labial face and appear to be more variable in their widths. Despite the occurrence of some similarities in the enamel scratches between ursids and hominids at Krapina, the study of anterior dental marks provides information about manipulative activities which are unique to ancient humans. © 1997 by John Wiley & Sons, Ltd.

Ornaments Made from Animal Teeth in Human Burials at Tuzovskiye Bugry-1 and Their Relevance to Ethnic Processes in the Altai, 3rd Millennium BC

The article describes ornaments made of animal teeth (elk, beaver, badger, fox, marmot, musk deer, and ibex or mountain sheep) and found in ground burials at Tuzovskiye Bugry-1, Northern Altai. Ornaments made of the teeth of the two latter animals are especially informative since these taxa are not found in the Barnaul–Biysk area of the Upper Ob basin, nor did they inhabit the area in the historical past. The musk deer is distributed in the mountain taiga areas of Gorny Altai and Eastern Kazakhstan. Ibex and mountain sheep are typical representatives of alpine fauna. In the past, the northern boundary of their distribution range coincided with the Chemal River, the southern boundary lay in the Mongolian Altai, and the western, in Rudny Altai (Eastern Kazakhstan). Ornaments made from Ibex and mountain sheep teeth indicate ties with Gorny Altai, intermediary groups being those known from Solontsy-5 burial ground and Nizhnetytkesken Cave-1 burial. The co-occurrence of these ornaments with Dentalium, Corbicula ferghanensis Kurs. et Star., and Corbicula tibetensis Prash. shells points to ties with Western Central Asia. In this case, the likely intermediaries are the people of the Ust-Narym or Botai cultures. Alternatively, groups from Western Central Asia or Eastern Kazakhstan may have migrated to the Altai.     

Alveolar bone status of some pre-seventeenth century inhabitants of Taumako,Solomon Islands

The alveolar bone condition of 34 pre-seventeenth century Solomon Island Polynesians aged 20–35 years was investigated from dental remains. The distance between the cementoenamel junction and the alveolar crest (CEJ-AC distance) was measured for six index teeth. The mean CEJ-AC measurements for each tooth, which ranged from 3.9 to 7.9 mm, greatly exceeded the distance of 2 mm frequently cited as representative of teeth supported by healthy bone. Many pathological bony defects were seen, suggestive of episodes of acute periodontitis with remissions to a quiescent phase.     

THE ORIGINS OF THE ANDRONOVO (FEDOROVKA) POPULATION OF SOUTHWESTERN SIBERIA,BASED ON A MIDDLE BRONZE AGE CRANIAL SERIES FROM THE ALTAI FOREST-STEPPE ZONE

A multivariate analysis of measurements taken from Andronovo (Fedorovka) cranial samples from the forest-steppe part of the Altai has revealed certain components that are likely to have contributed to the origins of this population. One component, resembling the robust (Cro-Magnon) variety observed in many Andronovo groups, would appear to have been introduced by migrants from the Kazakhstan steppes. Another component – Mediterranean, i.e., characterized by dolichocrany and narrow face, stemmed from the pre-Andronovo Bronze Age populations of southwestern Siberia, being especially noticeable in Andronovo (Fedorovka) groups of Rudny Altai and decreasing in the eastern and northern directions. The third component, on the contrary, becomes more and more prominent as one moves northward. This component was evidently associated with the Western Siberian native peoples. Its proportion in the forest-steppe zone of the Altai was minor, while being larger in the sub-taiga regions situated to the north.     

Tooth wear in two ancient populations of the Khazar Kaganat region in the Ukraine

Tooth wear is a common phenomenon in archaeological material. It has been related to the abrasiveness of diet and to the tribological attrition of teeth of individuals. Numerous investigations have been carried out in north and middle American samples as well as African anthropological material. Not much is known about tooth wear in European cultures. Eleven skulls from Chervona Gusarovka, and 14 skulls from the Upper Saltov sites of the Khazar Kaganat region (8th–10th centuries AD) in eastern Ukraine, with different diets were examined. A total of 208 teeth were studied for tooth wear, caries prevalence and periodontal status. Abrasion grades were determined according to a standardised classification and statistically evaluated. Periodontal status was measured using the distance between the enamel‐cementum junction and alveolar crest and the gingival attachment level respectively. Tooth wear was significantly different (P < 0.01) between the two populations. A low caries prevalence of 4.2% in the Chervona Gusarovka population and 1.7% in the Upper Saltov population was found. Significantly more alveolar crest bone resorption on the lingual side was found in the premolars and anterior teeth of the Chervona Gusarovka population. No significant differences were found regarding gingival attachment levels and gingival recession. It is concluded that the content and mode of food preparation influenced tooth wear, as reflected by the prevalence of dental caries and periodontal diseases in these ancient populations.

Efficient but destructive: a test of the dental wash technique using secondary electron microscopy

The Boyadjian et al dental wash technique provides, in certain contexts, the only chance to analyze and quantify the use of plants by past populations and is therefore an important milestone for the reconstruction of paleodiet. With this paper we present recent investigations and results upon the influence of this method on teeth. A series of six teeth from a three thousand years old Brazilian shellmound (Jabuticabeira II) was examined before and after dental wash. The main focus was documenting the alteration of the surfaces and microstructures. The status of all teeth were documented using macrophotography, optical light microscopy, and atmospheric Secondary Electron Microscopy (aSEM) prior and after applying the dental wash technique. The comparison of pictures taken before and after dental wash showed the different degrees of variation and damage done to the teeth but, also, provided additional information about microstructures, which have not been visible before. Consequently we suggest that dental wash should only be carried out, if absolutely necessary, after dental pathology, dental morphology and microwear studies have been accomplished.     

Reliability of the Assessment of Periodontal Disease in Historical Populations

Periodontal disease is the destruction of all portions of periodontium. However, only periodontitis, based on whether attachment loss has occurred, can be detected in archaeological material. Therefore, several methods have been used to assess the frequency of periodontitis in past populations. The main scope of this study is to determine whether diagnoses of periodontitis through various methods are consistent with diagnoses obtained using the radiographic method. The samples (35 individuals, 576 teeth) were selected from Radom Cemetery's collection (in use between 1790 and 1811). For each individual, a periodontal status assessment was made using the following parameters: (i) measuring the distance between the cement–enamel junction (CEJ) and the crest of the alveolar bone (AC); (ii) the degree of root exposure; (iii) presence of the inter‐dental septum; (iv) dental calculus; (v) scoring system on the texture of the alveolar bone (Kerr's method) and (vi) radiography. In the studies, a correlation was found between the radiographic images and Kerr's method (r = 0.92) and root furcation (r = 0.96). Increasing degree of change on the alveolar bone is connected with increases in the CEJ–AC distance. A relationship between the frequency of the prevalence of dental calculus and changes on the alveolar bone was found. It means that the radiographic method, which is not always possible to use in archaeological collections, can be replaced by the presented macroscopic methods.

A dental study comparing age estimations of the human remains from the Swedish warship Vasa

The great Swedish warship Vasa capsized and sank in Stockholm harbour on her maiden voyage in 1628. The ship was raised from the seabed in 1961 and skeletal remains were recovered from at least 25 individuals, with teeth and jaws from 17 of them. The skeletal material was odontologically examined, including dental radiographs. Teeth lost both ante‐mortem and post‐mortem were recorded and variations in tooth anatomy noted. Acquired changes were recorded including enamel hypoplasia, attrition, dental caries and periodontal recession. Age estimations based on a separate odontological study, osteological changes and tooth attrition had been made in 1989. Ages were estimated additionally by three non‐destructive dental methods based on (a) the length of the apical translucent zone, (b) selected measurements both on intact teeth and from ratios on dental radiographs and (c) ratios of the length and width measurements on dental radiographs from selected teeth. Several sources of post‐mortem changes had been observed, among them vivianite in 33 teeth from four individuals. The results of the dental examination showed that few teeth had been lost ante‐mortem, there was a low caries rate and little loss of periodontal attachments. With few exceptions, there is fairly good agreement between the different methods of estimating age. Age estimates based on dental attrition were, however, significantly different from the other dental methods and age estimates calculated from apical translucency ought to be regarded with scepticism due to post‐mortem changes. The chronological ages of the victims will never be known, but age estimates based on all the age‐markers available will probably reach a fairly close approximation.

Periapical Lesions in Intentionally Modified Teeth in a Skeletal Sample of Enslaved Africans (Lagos,Portugal)

Intentional dental modifications are alterations of teeth usually performed as a ritual for aesthetic or identity purposes. However, the execution of the technique is not exempt from risk and can be related to a higher prevalence of dental pathology, more specifically through the exposure of the dental pulp and consequent periapical inflammation. With the aim of analysing the relationship between intentional dental modifications and periapical inflammation, the current study evaluated 81 skeletons (49 women, 19 men, and 13 individuals of unknown sex) of enslaved Africans from Lagos, Portugal (15th–17th centuries), of which 50 (61.7%) had intentionally modified teeth. In all, 2285 sockets and 2063 teeth were observed. Two hundred and three intentionally modified anterior teeth (27.2%) were identified. Twenty five individuals (30.9%) and 54 teeth (25 anterior and 29 posterior) showed macroscopic evidences of periapical lesions. In the anterior dentition, intentional modification was identified as the probable aetiology of 17 (68.0%) periapical lesions, mostly granulomata or cysts, but also abscesses. The association between intentional modifications of the dentition and the presence of periapical lesions was found in both the maxilla and mandible. These results suggest that this cultural practice can predispose teeth to periapical inflammation, which may cause pain and sensitivity to cold, heat, and pressure, and probably had a negative impact on the quality of life of these individuals.

Dental Pathology,Trauma and Attrition in a Zambian Iron Age Sample: A Macroscopic and Radiographic Investigation

Using morphological and radiographic methods, we analysed the dentitions of 24 individuals from Ingombe Ilede and Isamu Pati Zambian Iron Age archaeological sites. In this study, we determined the frequency and distribution of attrition, pathological conditions and dental trauma. This research also presents the first view of dental health for an Iron Age population in southern Africa. In total, 482 teeth were available for this study with 287 teeth missing, where 50 of these were lost antemortem and one individual had an erupted supernumerary first mandibular incisor. With the use of radiography and morphology, 21.5% (104/482) of the analysed teeth had at least one pathological condition or evidence of dental trauma. Some interesting dental aspects found and discussed in this paper are linear enamel hypoplastic lesions, radicular resorption, periapical lesions, fractures, dental modification and carious lesions. Many of these features were diagnosed with radiography, and this was especially important for those found below the cemento‐enamel junction (p = 0.0202) that are less obvious with macroscopic investigation alone. Additionally, the quantity and direction of dental attrition was studied. There were observed sex differences with the direction of wear, likely representing a sex‐specific cultural practice of using teeth as tools. Overall, the results show that this sample suffered relatively little from dental problems, and many of those observed features were associated with the traumatic procedure of dental modification, whereas others were age and diet‐related. Additionally, with the use of radiography, rare dental fractures and other features were diagnosed; these results demonstrate the requirement for its application in dental studies on archaeological assemblages.

Storied landscapes makes us (Modern) Human: Landscape socialisation in the Palaeolithic and consequences for the archaeological record

The unusual nature of the Neanderthal archaeological record has attracted the attention of archaeologists for the past 150 years. On the one hand, the technical skill apparent in their lithic technology, the practice of symbolic cultural behaviours (such as burials), and their successful survival in harsh environmental conditions for more than 200,000 years demonstrate the adaptive success and underlying humanity of the Neanderthal populations. On the other hand, the apparent lack of abundant and repeated use of symbolic material culture has resulted in a number of researchers arguing that these populations were largely incapable of symbolism – a conclusion with significant implications for social organisation. This paper reviews ideas regarding the use of ‘place’ or ‘landscape’ by Neanderthals and argues that the identified differences between the archaeological records of Neanderthals and late Pleistocene Modern Humans is not so much the result of significant variance in cognitive capacities, but rather the use of contrasting approaches to interaction with the physical landscape. ‘Landscape socialisation’ is a Modern Human universal, but what if Neanderthals did not participate in this kind of landscape interaction? Would this difference in behaviour result in the apparently contradictory archaeological record which has been created? The ideas presented in this paper are drawn together as a hypothesis to be developed and tested.     

Visual and radiographic assessment of dental caries by osteologists: a validity and reliability study

In the skeletal remains of earlier populations, the presence and severity of dental caries preserves evidence about general health and diet. The quality of the data collected on dental caries is highly dependent on the diagnostic skills of the examining osteologist. A major barrier to more detailed data is reliance on visual inspection only. The present study compared quantification of carious lesions by osteologists, using both visual and radiographic inspection. Four osteologists with varying experience of caries diagnosis registered the presence and extent of dental caries on the crown and root surfaces of 61 teeth sourced from three different samples: archaeological, anthropological and modern. The teeth were subsequently sectioned to provide a control or standard reference. The interobserver differences were calculated as sensitivity (observer correctness in identifying teeth with caries disease). The two observers with more experience of dental paleopathology showed higher agreement with the standard reference than the other two observers, i.e. they correctly diagnosed more carious lesions. The most pronounced interobserver difference was for radiographic inspection of root surfaces. The recordings by the two experienced observers conformed much more closely with the standard reference than those of the less experienced observers. The results confirm that experience has a major influence on practical observations in dental paleopathology. The quality of collected data on dental caries could be enhanced by improving osteologists' knowledge of the disease process and the application of uniform, unambiguous criteria for registration of carious lesions.

Cleft Lip Case in a Middle Bronze Age Young Man from Altai,Russia

Oral cleft (OC) is a common congenital anomaly in humans, which occurs in approximately one per 700 live births. However, cleft skulls are found relatively seldom in archaeological specimens, especially for the bc period. Mortality of infants with OC was apparently high because of breastfeeding difficulties and culturally sanctioned rejection of them in the past. This paper presents one of the most ancient cases of OC in Eurasia. The finding comes from the Middle Bronze Age pastoralists' cemetery in Altai, Russia. The skeletal remains have been radiocarbon dated to 1883–1665 cal bc . Cranial and dental measurements, computed tomography and radiography have been used to examine this malformation. The facial sculpting reconstruction has been performed to visualise the ante mortem appearance of the cleft face. Besides, δ¹³C and δ¹⁵N isotope analysis was used for a comparative study of the diet of the cleft individual. It has been established that a young man from Altai was affected by complete bilateral cleft lip and alveolus, which is a very rare form of typical OC. This defect is associated with dental anomalies such as hypodontia, microdontia, and ectopia as well as with dysmorphology of the facial complex outside the cleft area, including mild hypertelorism, hypoplasia of nasal bones and antheroposterior maxillary deficiency. Furthermore, aplasia of the frontal sinuses and the sacral spina bifida occulta have been observed. These findings are consistent with clinical data indicating strong correlation between development of a major defect and multiple minor anomalies. The results of the study also suggest that there was tolerant attitude towards the facial deformities among the ancient Altai pastoralists. Copyright © 2016 John Wiley & Sons, Ltd.
