For all taxa residuals were only calculated against the four determined wear stages. Abbreviations in all tables: st.-dev. – standard deviation, L – length, B width, mesF – number of "fossettes" in anterior part of tooth, distF – "fossettes" in distal part of tooth, res - residual; lower case letters indicate mandibular teeth, upper case letter maxillar teeth.
