TABLE 1. Chi-square tests evaluating differences between the samples of murids of the different fossil assemblages from MCC. In light gray the moderately significant differences (0.05<p<0.1), in dark grey the highly significant differences (p<0.05); df: degrees of freedom; 5df when Stephanomys sp. is absent in both layers.
