A new framework of the evolution of the ctenodactylids (Mammalia: Rodentia) in Asia: new species and phylogenetic status of distylomyins Oliver Pérez, Adriana Carro Rodríguez, Patricia María López Guerrero, Paloma Daxner-Höck, Gudrun Two new species of ctenodactylid rodents, Prodistylomys taatsinius sp. nov. and Prodistylomys mongoliensis sp. nov., are described from the Valley of Lakes, Central Mongolia. They represent the first record of this genus in Mongolia. Prodistylomys is characterized by a simple dental pattern and high hypsodonty, reflecting an adaptation for tough vegetation in a dry environment, which is congruent with the aridification event that took place during the Late Oligocene and Early Miocene. We performed the most complete phylogenetic analysis combining the largest sampling in the family Ctenodactylidae and the best-represented stratigraphical distribution for the sample. This allowed us to propose that the origin of ctenodactylids lies in East Asia during the Eocene, and after that, the group dispersed through western Asia, Europe, and Africa. The presence of several similar rodent taxa in Mongolia, Kazakhstan, and China confirms that these areas were part of a large bioprovince covering most of central Asia during the Oligocene and Early Miocene. 2024-06-04T17:39:24Z 2024-06-04T17:39:24Z 2023-08-24 journal article Adriana Oliver, Patricia M Carro-Rodríguez, Paloma López-Guerrero, Gudrun Daxner-Höck, A new framework of the evolution of the ctenodactylids (Mammalia: Rodentia) in Asia: new species and phylogenetic status of distylomyins, Zoological Journal of the Linnean Society, Volume 199, Issue 3, November 2023, Pages 633–655 0024-4082 10.1093/zoolinnean/zlad030 https://hdl.handle.net/20.500.14352/104695 1096-3642 https://doi.org/10.1093/zoolinnean/zlad030 https://academic.oup.com/zoolinnean/article-abstract/199/3/633/7250090 eng CT42/18-CT43/18 PGC2018-094955-A-100 PGC2018-094122-B-100 Research Group UCM- 910607 (P-10505-GEO, P-15724-N06 P-23061-N19 restricted access Oxford University Press
