Abstract (in english)
   More than 1000 isolated molars of the advanced cricetids with high-crowed molars (the subfamilies Arvicolinae; the "microtoid" Baranomyinae, Prometheomyinae and Trilophomyinae) from the early Pliocene (MN 15b) in the lignite quarry "Römerstrasse" at Wölfersheim in the Horloff Basin about 30 km north-east of Frankfurt am Main represent the following forms: Mimomys (Mimomys) hassiacus Heller 1936, Mimomys (Cseria) gracilis Kretzoi 1969, Dolomys occitanus /Thaler 1956), Germanomys weileri Heller 1936, Baranomys longidens (Kowalski 1960), Baranomys kowalskii (Kretzoi 1962) and Trilophomys vandeweerdi Brandy 1979. Later, more extensive examinations revealed the unexpected record of two forms with rooted molars which represent ancestral formms of two lemming tribes of the subfamily Arvicolinae, the Synaptomyini (Tobienia kretzoii n.g., n.sp.) and Lemmini (Lemmini n.g., n.sp.).
   The new genus Tobienia shows close affinities to the extant North American genus of the Northern Bog Lemming Mictomys True 1894, the history of which in North America is described in detail. The oldest record, Mictomys vetus (Wilson 1934), has rootless molars and is about 1.5 Ma younger than the fauna of Wölfersheim. The assemblage of both mastodont Anancus arvernensis and Mammut borsoni and a tapir Tapirus arvernensis, together with the advanced cricetids supports a Late Ruscinian (mammalian zone MN 15b, i.e. approx. 4 Ma) age for the Wölfersheim fauna
