Abstract

Ferganodonnarynensis gen. et sp. nov. is represented by a lower molariform tooth from the Middle Jurassic (Callovian) Balabansai Svita in Kyrgyzstan. The new genus is allied with Klamelia zhaopengi Chow and Rich 1984 from the Middle Jurassic Shishugou Formation in Xinjiang, northwest China to the new family Klameliidae based on parallelogram-shaped lower molariforms, imbricating rather than interlocking of cusps e-d-f, by a peculiar distolabial cingulid cusp, and by vertical folding of the enamel on the labial crown side. The new family Klameliidae fam. nov. is most similar to Gobiconodontidae by the structure of the molariform teeth and represents a previously unrecognized radiation of eutriconodontan mammals possibly endemic to Central Asia.

Field work in Kyrgyzstan in 2000–2003 was carried out in cooperation with the M. M. Adyshev Institute of Geology of the National Academy of Sciences of the Kyrgyz Republic. The former director of this institute, Prof. Apas A. Bakirov (Bishkek) is thanked for his support. Zhe-Xi Luo and two anonymous reviewers provided valuable comments. Wolfgang Müller (Freie Universität Berlin) and Katrin Krohmann (Forschungsinstitut Senckenberg, Frankfurt am Main) assisted in the SEM. This project was funded by the Deutsche Forschungsgemeinschaft (DFG; Ma 1643/8 and 436 RUS 113/602/0-1-2). The work of TM was additionally supported by a Heisenberg grant (DFG) and the work of AA by a Russian Fund of Basic Research (RFBR) grant 04-04-49113, President’s of Russia grant MD-255.2003.04, and the Russian Science Support Foundation.
