Hipparionin dental microwear: Tables

TABLE 1. Descriptive statistics of each DMT parameter for all the hipparionin populations included in the present study. Mean body mass (BM) and the mean values of the textural parameters are also shown for each hipparionin group. Asfc = complexity, epLsar = anisotropy, HAsfc = heterogeneity of complexity calculated with a 64 cells mesh, Tfv = textural fill volume, N = sample size, sem = standard error of the mean.

Note: Fossil sites of Pentalophos and Ravin de la Pluie (a); Dytiko-1, Dytiko-2 and Dytiko-3 (b); Mytilinii A and Mytilinii B (c). Mean body mass estimations were based on metapodial measures and were calculated in this study (d) or obtained from: Vlachou (2013) (e), Orlandi-Oliveras et al. (2018) (f) and Pesquero and Alberdi (2012) (g).

TABLE 2. Results of the Principal Component Analysis performed with the four DMT variables. Percentage of variance explained by the principal component and contribution of each variable to the principal components are shown. r: correlation coefficient between the DMT variables and the principal components; r2: proportion of variance of the principal component explained by each variable.
