Abstract
The small mammals Myomiminae indet. (Gliridae), Leptodontomys cf. gansus Zheng and Li, 1982 (Eomyidae) and the new species Keramidomys sibiricus nov. spec. (Eomyidae) are described. They were collected from six layers of the middle to upper part of the Tagay-1 section on Olkhon Island. The glirid Myomiminae indet. is represented by only a few isolated teeth, the small eomyid Leptodontomys cf. gansus by a mandible with two teeth, and the second small eomyid Keramidomys sibiricus nov. spec. by several isolated teeth and a mandible. The ancestral tooth characteristics of Keramidomys sibiricus nov. spec. indicate an early evolutionary stage of Keramidomys in Asia. The suggested age of the assemblage is Early/Middle Miocene transition.
期刊介绍：
Palaeobiodiversity and Palaeoenvironments is a peer-reviewed international journal for the publication of high-quality multidisciplinary studies in the fields of palaeobiodiversity, palaeoenvironments and palaeobiogeography. Key criteria for the acceptance of manuscripts are a global scope or implications of problems on a global scale significant not only for a single discipline, a focus on the diversity of fossil organisms and the causes and processes of change in Earth’s history. The topics covered include: Systematic studies of all fossil animal / plant groups with a special focus on palaeoenvironmental investigations, palaeoecosystems and climate changes in Earth’s history, environment-organism interaction, comparison of modern and ancient sedimentary environments, palaeoecology and palaeobiogeography.
