Mandible — The mental foramen is placed under the reentrant valley of mi. M

1 — The first molar is much wider than long. The paracone is only slightly lower than the. metacone, but the parastyle is much shorter, than the metastyle, so AW < PW. The mesostyle is short and undivided The protocone is very high. The trigone basin is posteriorly bordered by high metaloph. The posterior border is distinctly notched. The hypoconal flange is short, but a low a hypocone is present. mi/rm — A buccal cingulum is present on the molars. The protocone is very high. Entoconid crest is low. nu — The talonid is unicuspid The species is reported from the Middle Miocene MN 6 Zone (Sansan, BAUDELOT 1972). In Hungary it has been found from Mátraszőlős and Hasznos (MÉSZÁROS: Middle Miocene Insectivores from Hungary, in prep.) Familiy Talpidae FISCHER VON WALDHEIM, 1817 Talpidae gen. et sp. indet.

However, on the basis on the few present detailes and the measurements, we can identify this form as the same as MÉSZÁROS found in the Middle Miocene (MN 6, KORDOS 1981 and 1986) locality of Hasznos (see MÉSZÁROS: Middle Miocene Insectivores from Hungary, in prep.) Conclusions regarding the insectivores There were only 3 fragmented mandibles in the 42 specimens of the Sámsonháza insectivore material. Rate of the isolated teeth is very high (93%). However, the braking pattern is not too intensive. There are slight digestive marks on the Paenelimnoecus mandibles, and somewhat more intensive ones on the Galerix jaw (the enamel surface is also digested here). The remains supposedly were accumulated mostly by water in the locality, but transported here in not too long way. Few specimens were killed by predators. We can determine the age of the insectivore sample as Middle Miocene, Astaracian, MN 6. In the presence of Galerix exilis, Plesiodimylus chantrei and Paenelimnoecus crouzeli the Insectivora fauna is nearly related to the French locality of Sansan. G exilis and P. crouzeli is present also the Hungarian Mátraszőlős site. These species and the Sámsonháza talpid form is listed from Hasznos, a locality nearby Sámsonháza. We have to take the note, that the studied assemblage is very poor in species, even if we consider the bad preservation of the material.

2 1.51 mm 1.96 mm 1 d4 1.61 mm 1.44 mm 1 rri3- (Figure 4: 1) 2.12 mm 1.88 mm M 1-2 — The height of the protocone, metacone and paracone is equal. The anteroloph and the anterosinus are strongly worn. There is a minor mesostile between the paracone and the metacone. d» — The outline of the occlusal surface is subtriangular. The central basin dominates the crown. The protoconid and the metaconid are two small conelets on the tight anterior margin. The hypoconid and the entoconid are melted into the posterolophid. rri3 — In the anterior part of the toothcrown there are the protoconid-metalophid and the metaconid-anterolophid system. A narrow furrow divides the protoconid-metalophid from the anterolophid. The lingual part of the metalophid is melted into the anterior wall of the central valley which is closed by the mesoconid, hypoconid and the posterolophid. Spermophilinus bredai is very common in the European Middle Miocene. The stratigraphical range is MN 5-MN 10 (ÁLDANA CARRASCO 1992). In Hungary it is known from Sámsonháza, Mátraszőlős 2. (GÁL et al. 2000), Felsőtárkány 3/2 (FIÍR et al. 2001).
