Composite Bows from Uch-kurbu in Kyrgyzstan

The article addresses the topic of composite bows from nomadic sites in Tien Shan and Zhetysu. Horn plates from bows discovered in 2008–2009 at Uch-Kurbu on the Tosor River, the Issyk-Kul Depression (Kyrgyzstan), are described and analyzed. The original design of the wooden core of the bow and the location of horn plates thereon are reconstructed. Based on our earlier classification of weapons, these are composite bows of the Xiongnu-Xianbei period. Two subtypes are identified, based on the design of plates at the ends of the bow. Evidently, composite bows with end, medio-lateral, and medio-frontal plates were the most efficient range weapon of the period.     

An Experimental Technological Study of Upper Paleolithic Kostenki-type Figurines

Principal stages in the manufacture of zoomorphic, polyiconic, and anthropomorphic Upper Paleolithic figurines are reconstructed. General factors determining their characteristics include universal conventions of representation and the limited set of technological operations available, whereas local factors include specific ways of processing materials and combining artistic techniques, the manner of individual masters, technological faults and accidents, as well as taphonomic processes.     

Clarifying prehistoric parasitism from a complementary morphological and molecular approach

This paper reports an approach to the identification of prehistoric parasitic infection, which integrates traditional morphological methods with molecular methods. The approach includes the strengths of each method while mitigating the limitations. Demonstrating the efficacy of this approach, we provide a case study from a 1400 year old desiccated fecal sample from La Cueva de los Muertos Chiquitos, archaeological site, near Rio Zape, Durango, Mexico. Traditionally prepared microscope slides were processed via microscopy and tentative ascarids were identified. Information regarding the parasites' developmental stage was recorded. DNA was then extracted directly from the slide material. From this DNA extract, a small segment of the 18S ribosomal RNA gene variant that is specific to Ascaris, and its phylogenetically close relatives, was targeted for PCR amplification and sequencing. Phylogenetic analysis of the DNA sequence best matched a member of physalopterids, rather than ascarids, with a single exception of a match to Contracaecum spiculigerum. Subsequent extractions, amplifications and sequencing of the original rehydrated coprolite material confirmed these results. The C. spiculigerum sequence represented a phylogenetic anomaly and subsequent analysis determined the sequence was an error in the BLAST database, likely attributable to misidentification of juvenile specimens prior to sequencing and submission. Physaloptera are a difficult genus to identify morphologically and can carry major health burdens. They may be underreported in humans, in part, because of morphological similarities to the more common human parasites belonging to ascarids. We conclude that integrating traditional morphological methods with molecular methods can help resolve this issue, in both contemporary and prehistoric populations.
