10 Hl ' R . J- & fr Unfortunately, systematic collection of the vertebrate fossils was not effected from this series, because the identification of the old localities was impossible. New localities were found by HÍR J. in the deep Oszkoruzsa Valley of the Buda Hill close to the type section of the Sámsonháza Formation (Figure 1). The sampling had been managed from 1995 to 1999. During the course of the field works, 4 metric tonnes of sediment was carried from the localities in all. During the winters the hard material was kept on the frost. The washing was possible only after the freezing. We applied a sieve-system made after the description of ROS, L. GY DAAMS & FREUDENTHAL (1988a) for washing with the finest mesh size 0.5 mm. In the sections of the four known localities the fossil (bones and great deal of molluscs) bearing calcareous mud layer is bedded everywhere on the top of the marine series and below the fluviatile gravels. The majority of the vertebrate material was collected from the locality Sámsonháza 3. (Figure 1-2). The rich molluscan material is under the elaboration of J. KÓKAY, the herpetofauna is studied by M. VENCZEL. The first results of the collection and the elaboration were published in Hungarian with English abstract (HÍR et al. 1998). Systematics Class Mammalia LlNNAEUS, 1735 Order Insectivora BOWDICH, 1821 The insectivore remains are poorly preserved, most of them are isolated teeth. The site yielded 42 erinaceid, dimylid, soricid and talpid remains, with 5 species. In their preliminary report on Sámsonháza locality HiR et al. (1998) had presented a faunal list on these insectivores, but after the detailed systematic researches we had to change it in some points. The morphological nomenclature is used after HUTCHINSON (1974), REUMER (1984) and RUMKE (1985). The measurements are taken after ENGESSER (1980) and REUMER (1984). In the figures scale bars = 1 mm.

A hard posterocrista runs from its top backwards. The parastyle is hardly visible. The protocone and the hypocone are much lower than the paracone, they are separated together by a wide and deep walley. M 1 — The tooth is three-rooted. The protocone is the largest cusp. Its anterior arm runs parallel to the anterior side, and reaches to the paracone. A very low protoconule is situated on this arm. The hypocone is very strong. The paracone and the metacone are high, the metaconule is somewhat lower. Its posterior arm ends at the posterior cingulum. The posterior arm of the metacone is long and extends postero-labially. M 2 — The second molar also has three roots. It is very similar to the previous one. Its metastyle is much shorter than that of M 1 . M 3 — The toth is triangular, three-rooted, it has three cusp and a deep trigone basin between them. The anterior cingulum is well developed. p4 — The tooth is two-rooted. The para-, proto- and a metaconid are well developed but the metaconid is the lowest and weakest one. The paraconid is low, but distinct. The talonid is very short and low. There is a little cusp in the postero-lingual corner. The talonid is posteriorly bordered by a sharp ridge. The buccal cingulum is present. mi — The trigonid of this two-rooted big molar is much shorter than the talonid. The buccal cingulum is well developed. The proto- meta- and paraconid have the same height. The paraconid is connected to the protoconid by the well-defined paralophid. The posterior arm of the entoconid is connected to that of hypoconid. The entocristid is slightly developed. This form can be ranged in genus Galerix and separated from Scbizogalerix by the undivided mesostyle on the M 1 and M 2 (Figure 3: 1-3) (ENGESSER 1980). There are two stratigraphically and morphologically similar species to G. exilis in the fosil insectivore fauna of Europe. G. stehlini is somewhat larger as this form and the metaconid is strongly reduced in p4 (ZlEGLER 1983) (Figure 3: 1). In the MVM 2 of G. soaalis the posterior arm of the metaconule reaches up to the metastyle, while ends at the posterior cingulum at the Sámsonháza form (DEJONG 1986) (Figure 3:2-3).
