Abstract

The assemblage of small mammals from a site near Yeniköy (Anatolia) is described. The assemblage was collected by screen-washing a sample from a locality in the Selimye Formation (Sivas basin). The site has a magneto-stratigraphic calibrated age of 29 Ma (younger part of the early Oligocene). The murids dominate in this relatively small collection with Eucricetodon and Pseudocricetodon. In addition, a dipodid, an unidentified erinaceide and the new baluchimyin hystricognath genus and species Zorania milosi nov. gen. et nov. sp. are present. The study of Eucricetodon, Pseudocricetodon and Zorania nov. sp. includes an analysis of incisor enamel microstructure. The incisor microstructure of Eucricetodon shows that there are several parallel long-living lineages within the genus. The Anatolia-Balkans biogeography of the late Eocene-Oligocene is reviewed. Its rodent assemblages are characterised by dominance of murids and presence of taxa that are known from low-latitude Asia. The Paleogene Anatolia-Balkans biogeographic province, is therefore rather different from those of western European and the Indian subcontinent.

We gratefully acknowledge the facilities offered by the MTA (Turkish Geological Survey) during the field parties many years ago, in particular Gerçek Saraç (now retired) is thanked for his support. The SEM pictures of the cheek teeth were made by Tilly Bouten (Utrecht University) and retouched by Jaap Luteijn (formerly at Utrecht University). The map of Figure 1 was prepared by Margot Stoete (Utrecht University); Leonard Bik (Utrecht University, Earth Sciences Geolab) assisted in the preparation of the incisor samples. The SEM photographs of incisor microstructure were made by Hans Meeldijk (Utrecht University, Electron Microscopy Department). A discussion with Daniela Kalthoff (Swedish Museum of Natural History, Stockholm) sharpened our interpretation of Eucricetodon incisor structure. Jan van Dam (Utrecht University) critically read the typescript. We thank Gudrun Höck and Lars van den Hoek Ostende (Naturalis, Leiden) for their careful and detailed reviews.
