FRAGMENTA MINERALOGICA ET PALAEONTOLOGICA 10- 1981 p. 65-70 Bat remains from the Upper Pleistocene localities at Süttő, Hungary By GY. TOPÁL (Received November 30, 1980) Abstract: A faunal list of fossil bats along with osteological details and evaluation of the findings from seven localities at Süttő, Hungary is given. The limestone quarries at Süttő with their interesting fossil faunas already draw the attention of T. KORMOS in the twenties. He (KORMOS 1925; FLEISSIG & KORMOS 1933-34) published a faunal list which was considered as a mixed-up fauna by subsequent authors (KRETZOI 1953; JÄNOSSY 1979). To the four species of bats In the first list by Kormos (Rhinolophus ferrumequinum Schreber, Myotis oxygnathus Monticelli, Miniopterus schreibersi Kuhl, Nyctalus s p.) another one: Myotis bechsteinl Kuhl was added in the second List (FLEISSIG & KORMOS 1933-34). At least three of the above bats suggest a mild temperate climate similar to the present one in the Carpathian Basin. Further excavations which were performed between 1965 and 1974 under the directions of Dr. D. JÄNOSSY of the Hungarian Natural History Museum yielded a good number of bat remains from the Early Upper Pleistocene period. This period seems to be one of the less known parts of the whole Pleistocene of Hungary. This is especially true when one considers the Investigation of fossil bats. The most surprising result of the recent studies is the discovery of a bat fauna higly similar in appearance and composition to our contermporary fauna of Chiroptera, which was actually missing during the major part of the Pleistocene, except its earliest portion. The history of explorations, description of the localities at Süttő, as well as their fossil faunas other than bats are brilliantly worked out by JÄNOSSY & KROLOPP (1981). Not all but most of the localities contained bat remains. These are Loc. No. 3, 4/2, 6/2, 6/3, 7/upper, 7/lower, 8/1, 8/2, 9, 12/A, 12/B. Locality No. 3 This material was collected In the years 1965-66. It Is rather moderate considering the number of species and their fragments. Besides four forms of Myotis and the Plecotus , there is no any trace of Rhinolophus . Apparently, the recently described Myotis kretzoii Topái is the most (relatively) common species here. This animal seems as a characteristic species of the Late Middle Pleistocene Solymár Horizon, and so, connects the fauna of Süttő with Solymár. The rather infrequent bones of Myotis bechsteini Kuhl suggest both the typical M. b. bechsteini and another form, probably M. b. robustus Topái. Myotis mystacinus Kuhl - Distal portion of a right humerus. One individual. Myotis kretzoii Topái - Two fragments of right mandibles each with P4-M3, right mandibular fragment with P3 and Mg, fully preserved left radius, distal fragm. of left radius, proximal fragm. of left radius, proximal fragm. of femur, sacrum. At least three individuals. Myotis nattererl Kuhl - Fully preserved left humerus. One Individual. As In other localities at Süttő (see below) along with the common M. kretzoii with great probability, the Natterer' s Bat is also present.
