Vertebr. Hung. XV. 1974. The First Record of Megaderma in Hungary (Pliocene Sediments of 0sztramo6, Locality 10) TOPÁL, György Natural History Museum, Budapest ABSTRACT: With notes on the first Hungarian record of a fossil Megaderma and the description of Megaderma janossyi n. sp., a list of mammalian species found at locality No. 10, Osztramos (Pliocene, "Postpannonian") is given. The status of Rhinolophus lissiensis is discuessed. Among numerous Pleistocene and Pliocene localities of fossils found in recent years at Osztramos Hill, North-east Hungary, locality No. 10 surrendered the fewest remains of mammals, both in numbers and in species. The site was discovered during the routine summer excavations led by the Hungarian Natural History Museum in 1971. It was a narrow (about 40 cm wide) fissure at a 80 m distance from locality No. 1 with Pliocene mammalian bone material (JÁNOSSY, 1972). The deep purplish-red sediment was found on the disturbed surface of the upper level of a limestone quarry at about 350 m a. s.l. On the very first occasion there was found the mandible of a megadermatid, cemented to the perpendicular hind wall of the fissure, and also the remains of a medium sized Rhinolophus . Subsequent collecting and washing of some kgs of clay sample yielded a very poor and fragmentary bone material. Up to the autumn of 1973, locality 10 became unaccessible and then disappeared, apparently owing to ground leveling works. Access of the area in the future also seems hopeless because of the greatly mechanized quarry operations. Yet however small and fragmentary the material is, it is still worthy of publication, mainly because of the occurence of Megaderma in it. The list of Mammals found J Petényia sp. Talpa sp.
