Abstract The two living species of bison (European and American) are among the few terrestrial megafauna to have survived late Pleistocene extinctions. Despite extensive bovid fossil record in Eurasia, evolutionary history European (or wisent, Bison bonasus ) before Holocene (<11.7 thousand years ago (kya)) remains a mystery. We use complete ancient mitochondrial genomes genome-wide nuclear DNA surveys reveal that wisent is product hybridization between extinct steppe ( priscus ancestors...

Abstract Sub-fossilised remains may still contain highly degraded ancient DNA (aDNA) useful for palaeogenetic investigations. Whether X-ray computed [micro-] tomography ([μ]CT) imaging of these fossils further damage aDNA debated. Although the effect on in living organisms is well documented, its impact molecules unexplored. Here we investigate effects synchrotron irradiation from Pleistocene bones. A clear correlation appears between decreasing quantities and accumulating dose-levels above...

The Amvrosiivka Upper Palaeolithic complex, which consists of a site and bison bone bed, is situated in the South-East Ukraine near city, upper reaches Kazenna ravine. In beginning it was found by geologists 1910 as assemblage bones, later determined detailed geologic map region paleontological seat natural origin (Meffert 1923). Thanks to archaeological exploration excavations, were held 1935 V. M. Evseev — scholar Stalin Regional Museum Local History, this location has come notice site....

У статті висвітлено столітню історію досліджень верхньопалеолітичних пам’яток материкової, степової частини півдня України, результатом яких є створення сучасної повноцінної бази для культурно-історичних і соціально-економічних доби верхнього палеоліту Східної Європи. Представлено дані про датування та культурну атрибуцію основних пам’яток. Акцентується увага на деяких маловідомих або раніше не досить повно висвітлених фактах, пов’язаних із вкладом тих чи інших офіційних неофіційних наукових...
