DESCRIPTION
The teeth are semi-hypsodont with flat occlusal surface and thick enamel ( Fig. 10 View FIG E-H). In M1 and M2 the occlusal surface consists of three enamel folds (anteroloph, medioloph and posteroloph) ( Fig. 10A, B View FIG ). The folds are divided by one lingual and two labial sinuses. In M2, the first labial sinus becomes an enamel-ring during the early stage of wear process. A distinct mesoloph is not developed, since it is involved in the medioloph. The occlusal surface of lower molars consists of three enamel folds (anteroconid, mediolophid, posterolophid). In the juvenile m1, the mediolophid is sometimes segmented in two parts ( Fig. 10D, H View FIG ). Th e folds are

divided by one labial and two lingual sinuses. The anteroconid contains 1-5 enamel rings in the juvenile stage of wear. Th ere is a large enamel ring in the lingual part of the mediolophid, which never forms a sinus during the wear process ( Fig. 10C, D View FIG ).
COMMENTS
The occlusal pattern of the m1s from the Felsőtárkány Basin does not show any tendency towards the typical morphotype (having a large sinus in the medioloph of m1) of A. rudabanyensis Kordos, 1989 . In the late Astaracian-Early Vallesian faunas of eastern Central Europe three Anomalomys species were described:
Anomalomys rudabanyensis from Rudabánya (MN 9; Kordos 1989, 2005), Anomalomys gaudryi from Belchatow A (MN 9; Kowalski 1994; Garapich 2002), Felsőtárkány 1, Felsőtárkány 3/2 (MN 7/8; Hír 2001, 2003) and Felsőtárkány-Felnémet 2/3 and 2/7 (MN 7/8; Hír 2006), and finally Anomalomys cf. gaillardi Viret & Schaub, 1946 from Götzendorf (MN 9, Rögl et al. 1993).
