TABLE 5 in Chilotherium schlosseri (Weber, 1905) (Rhinocerotidae, Mammalia) from the late Miocene of the foreland of the Eastern Carpathians in Romania

TABLE 5. — Differences of the dental morphology at different stages of wear on the P4 of Chilotherium schlosseri (Weber,1905) from Reghiu (ERIS-Rg/1987 001/6), Grebeniki (Pavlow 1913), Samos Island (Weber 1905) and Bacău (MNS-IBB 112), as illustrated on Figure 10. The crown height of the holotype of C. schlosseri from Samos Island is estimated based on Weber (1905: pl. VIII, fig. 1).
