First Record of Bats (Chiroptera, Mammalia) from the Middle Miocene non-karstic site Hasznos (Hungary, Nograd County)

We record the first fossil bats from the Middle Miocene non-karstic marshy-lagoonal deposits at Hasznos, northern Hungary. The bat material consists of mandible fragments of Miostrellus cf. petersbuchensis and Myotis bavaricus, the vespertilionid species until now recorded only from the Miocene sites of Germany. The discovery suggests an extensive palaeogeographical distribution of these species and connectivity of distribution ranges over the Central Paratethys region during the Late Badenian.
