[…] We examined 103 items identified as Micromys spp. (mostly isolated teeth and jaw fragments) from 14 Pliocene and Early Pleistocene sites in Central Europe. Namely, these were:MN15 Csarnóta 2 (Hungary, coll. MAFI Budapest): 8 M1, 13 m1 (type series of Micromys praeminutus Kretzoi, 1959; see , for details of the site).MN15 Gundersheim-Findling (Germany, coll. SMF Frankfurt a.M.): 2M1,2m1 . MN15 Vinogradovka 2 (Ukraine, casts in coll. SMF Frankfurt a.M.): 3 m1, 1 m2 (see ). MN15 Vinogradovka 3 (Ukraine, casts in coll. SMF Frankfurt a.M.): 1 m1 (see ). MN16 Ręmbielice-Królewskie II (Poland, coll. ISEZ PAN Krakow): 4M1, 2M2, 4 m1, 1m2, 1m3 (see ). MN16 Ręmbielice-Królewskie I (Poland, coll. ISEZ PAN Krakow): 1M1, 2m1, 1 m2 (). MN16 Zhevakhova Gora 15 (Ukraina, casts in coll. SMF Frankfurt a.M.): 3 M1, 4 m1, 3 m2 . MN 16/17 Gundersheim – Heller’s collection (Germany, coll. SMF Frankfurt a.M.): 1M1, 1m2 , . MN17 Včeláre 6/1 (Slovakia, coll. UK Praha): 13 maxilary fragment, 10 mandibular fragments, 12 M1, 8 M2, 4M3, 9m1, 9 m2, 4 m3 (see and for details of the site). MN17 Zamkowa Dolna Cave (Poland, coll. ISEZ PAN Krakow): 2 m1 (see ). MN17 Kotlovina 3 (Ukraine, casts in coll. SMF Frankfurt a.M.) : 1 M1, 2 m1 (see ). MN17 Beremend 11 (Hungary, coll. HMNH Budapest): 1 M1, 1 m1, 1 m2 (see ). Q2 Hohensülzen (Germany, coll. SMF Frankfurt a.M.): 2 m1 (see for details).In addition, we examined the type series of Micromys chalceus Storch, 1987 from the Chinese MN13 site Ertemte 2∶18 M1, 6 M2, 12 m1, 8 m2, 1 m3 (casts in coll. SMF Frankfurt a.M.; see for details) and a comparative series of 64 skull and mandibles of extant Micromys minutus from the Czech Republic and Slovakia (coll. Dept. Zoology, Charles University Prague), as well as 13 items from the Holocene/Vistulian sites, Rejtek and Tarkö (both Hungary) and Soutěska II, Zazděná, and Bašta (all Czech Republic) – comp. . The examination of the materials deposited in the above mentioned institutions in Czech Republic, Hungary and Poland was undertaken as part of research projects at the respective institutions (the authors - IH,LK,AN are ultimate authorities responsible for the respective collections). The material deposited in Senckenberg Institute, Frankfurt a.M. (SMF), concerned the previously published items (see ) and for purpose of the present project were examined by JW under permission of the collection curator (K. Krohmann).The stratigraphical position of particular samples is expressed in terms of the standard European biostratigraphic scale ( , ) and alternatively in units of the Neogene (MN) or Quaternary (Q) mammalian biozones (, ,–). For further stratigraphic correlates see .We follow the cusp nomenclature proposed by van de Weerd and Storch with regards to alternatives suggested by Lazzari et al. – cf. . The mandibular molars are denoted here in lower case (m1–3), the maxillar molars in upper case (M1–3).All items were photographed (mostly using an OLYMPUS ZX27 stereomicroscope). 56 dental measurements were taken (see ) with the aid of tpsDig image analysis software (by F.J. Rohlf). The states of 18 non-metrical variables were scored in terms of predefined character-specific scales (0,1.5) covering the observed variation; their definitions are in . Statistical analyses were performed using Statistica Software 8. Exploration analyses (correlation matrices, ANOVA, principal components analyses) were computed both for the set of all variables and, for metric and non-metric variables separately. The PCA results shown in – refers to set of non-metric variables. […]
