Table 4. Descriptive statistics of the upper and lower cheek teeth of Prodistylomys including the new species. All measurements are given in millimetres.Length and width represent the maximum antero-posterior and bucco-lingual distances. Abbreviations: Elem., element; N., number of teeth measured; min, minimum; max, maximum. For abbreviations of assemblages see Table 2.
