“…Two teeth were investigated: one modern intact molar extracted from a patient of the dental clinic of the Ural State Medical University (Ekaterinburg, Russia) and one archeological human molar excavated from the Bronze Age Kamenka burial of the Srubnaya culture (Kamenka village, Orenburg Region, Russia). 36 The teeth were thoroughly cleaned with deionized water and dried on air. Enamel and dentin were mechanically separated using a Dremel rotary tool.…”

Teeth and bones are important bioarchives, which can be altered because of diagenesis or burning (cooking, funerary cremations, and fires). Though heating and diagenesis are different processes, an experimental heating of modern bioapatite reproduces in a short time effects similar to diagenetic processes occurring over geological time. The thermal behavior of modern and archeological human enamel and dentin using the in situ thermo-Raman spectroscopy at 83-873 K was investigated to assess the structural changes in organic and mineral components of a tooth and their interrelationship. The ν 1 (PO 4 ) vibrational mode in apatite is the most anharmonic and responsible for the reaction of the structure to external influences. The γiP isobaric Grüneisen parameters for archeological (0.41) and modern (0.24) enamel are different from those for fluor-(0.17) and chlorapatite (0.17), which indicates a stronger reaction of P O bonds in bioapatite PO4 tetrahedra to temperature changes as compared with geologic samples. The anomalies of the thermal dependences of the ν 1 (PO 4 ) peak position and Δcorr PO 4 (T) autocorrelation function are caused by the combined effect of different factors such as breaking of hydroxyl and hydrogen bonds, the loss of adsorbed and structural water, collagen denaturation, organic phase combustion, and removal and relocation of B-and A-type carbonate ions. The thermal (273, 313, 341, and 363 K) and cold ($160 K) denaturation of collagen is reflected in the ν 1 (PO 4 ) and Δcorr PO 4 (T) dependences. The Δcorr PO 4 (T) differences between modern and archeological dentin and enamel are contingent on bioapatite composition (proportions of adsorbed and structural water, hydroxyl and carbonate ions, and trace elements as well as different types of organic matterlowmolecular noncollagen compounds and high-molecular collagen). The results obtained contribute to the knowledge about the thermal transformations of the mineral and organic phases of modern and archeological tooth tissues and allow their structural alterations to be evaluated.

Wool-focused economies yielded a pastoralist materiality that visibly shaped the lived experiences of Central Asian populations today. In this paper, we investigate the earlier application of fibers through a key mountain corridor for social interactions during Prehistory. We focus on the site of Chap 1 located in the highlands of the Tien Shan Mountains of Kyrgyzstan where researchers have found a complex agropastoral subsistence culture was established from at least ca. 3,000 BCE. The perishable materials that would have accompanied the early spread of cultural and technological traditions related to fiber-based crafts throughout this area are under-documented due to poor organic preservation. Hence, there has been little consideration of the role that textiles played in highland occupation and how woven fabrics might have facilitated settlement in the extreme climates of Central Asia. We address this ongoing problem through a multi-application survey of Chap’s unpublished textile evidence preserved as impressions in coarseware ceramics of its Final Bronze Age. We consider evidence that sheep wool formed a key cultural adaptation for surviving the extreme winters of Central Asia’s highland regions.
