Abstract

New findings of Stephanorhinus kirchbergensis (Jäger, 1839) remains, obtained from the Asian part of Russia, are described. The material includes 39 specimens from 13 localities in West Siberia and East Siberia. It considerably expands the geographic distribution of this species of rhinoceros. A series of 11 mandibles from Siberia, including one juvenile individual with deciduous teeth, is described for the first time. We also present a large set of data on well-preserved postcranial remains. The morphology and sizes of mandibles, teeth, and postcranial remains of adult individuals of S. kirchbergensis from Siberia are similar to individuals of this species described from European localities. A series of upper teeth was subjected to mesowear analysis to assess the diet of S. kirchbergensis from West Siberia. The chemical composition (including stable isotopes) of the Siberian Stephanorhinus teeth is analyzed for the first time. Comparisons of Siberian S. kirchbergensis with European S. kirchbergensis and West Siberian Coelodonta antiquitatis broaden our understanding of the ecology, variability, and evolution of S. kirchbergensis under climatic changes in continental settings from the Middle to the Late Pleistocene. Despite small samples, we can suppose that S. kirchbergensis was widely distributed in Siberia. Y.V. Lobachev.

标题西伯利亚金Stephanorhinus kirchbergensis的新发现

描述了在俄罗斯亚洲地区发现的Stephanorhinus kirchbergensis (Jäger, 1839)遗骨的新发现。这些材料包括来自西西伯利亚和东西伯利亚13个地方的39个标本。这大大扩大了这种犀牛的地理分布。来自西伯利亚的一系列11个下颌骨，包括一个具有乳牙的幼年个体，首次被描述。我们还提供了大量保存完好的颅骨后遗骸的数据。西伯利亚kirchbergensis成年个体的下颌骨、牙齿和后颅骨的形态和大小与欧洲地区描述的该物种个体相似。对西西伯利亚kirchbergensis的一系列上齿进行了细观磨损分析，以评估其饮食。首次对西伯利亚Stephanorhinus牙齿的化学成分(包括稳定同位素)进行了分析。西伯利亚kirchbergensis与欧洲kirchbergensis和西西伯利亚Coelodonta antiquitatis的比较，拓宽了我们对中晚更新世大陆气候变化背景下kirchbergensis的生态学、变异及其演化的认识。尽管样本很小，但我们可以假设S. kirchbergensis在西伯利亚广泛分布。Y.V.
