Fig 15. Tapir tooth wear–cusp height changes.
Relationship between the Δ cusp height (the difference of buccal–lingual cusp height) and wear (quantified as the relative loph distance RLD) in three tapir species. White rectangle = P2; White triangle = P3; White circle = P4; Grey diamond = M1; Grey rectangle = M2; Grey triangle = M3. Pearson’s correlations: T. terrestris: n = 108, R = -0.61, P<0.001; T. indicus: n = 35, R = -0.58, P<0.001; Spearman’s correlation: T. bairdii: n = 4, R = 0.20, P = 0.917.
