Természettudomány - Hír János: A Kárpát-medence középső miocén rágcsálófaunáinak rövid áttekintése

6. Rudabánya The most important Early Pannonian vertebrate fauna with a long faunái list and an abundant hominoid (Dryopithecns brancoi) material. The latest study of the rodent material is given by DAXNER -HÖCK & FEJFAR (manuscript). Remarks to the tables Tab. 1. Sciuridae Among the plotted species S. bredai was probable a ground squirrel. The other species were flying squirrels. One of them Hylopetes is living up to the présent time in the subtropical forests of South-Eastern Asia (BOUWENS & DE BRUIJN 1986). Tabs. 2.-3. Gliridae The list of the species is surprisingly abundant, but Statistical populations are very rare. Tab. 4. Eomyidae This rodent family became extinct without any living descendents. In the studied faunas there are only two gênera: Eomyops and Keramidomys. Tab.5. Cricetini I.: Democricetodon The material is very scarce. The listed 3 spacies were found only in the Carpathian Basin and two of them are known only from one locality. Tab. 6. Cricetini IL: Megacricetodon The dominant hamsters of the Middle Miocène faunas. The studied finds are not local éléments (like the above mentioned Democricetodon species), those are well known from the Bavarian and the Swiss molasse. Tab. 7. Cricetodontini: Cricetodon and Hispanomys The large sized hamster -like rodents are common éléments of the Miocène vertebrate faunas. In the Iberian Peninsula and in Southern France they left up to the Pliocène. In Switzerland those were found up to the MN 9 zone. In Turkey the range of the Cricetodontini reaches up to the end of the Miocène. In the Carpathian Basin this group disappeared during the zone MN 7/8. Tab. 8. Rare hamsters (Lartetomys, Collimys), Neocometes, Anomalomys Microtocricetus and beavers This last table is rather heterogene from systematical point of view. Neocometes was described from the Early- and Middle Miocène rodent faunas from Spain to Slovakia. Up to the présent time it was not found in Hungary and in Románia. Lartetomys is a very rare large sized cricetid occured in the faunas of the MN 5 -MN 6 zones. The Anomalomys genus is represented by the A. gandryi in the studied faunas. The morphological variability of this species is remarkable but a gênerai simplification in the morphology is possible to find from Neudorf to Felsőtárkány. After the comparision of the A. gandryi material from Felsőtárkány and the A. rudabanyensis from Rudabánya a direct filetic connection between the two species is improbable (HIR 2002). 31
