FIG. 8. — Bivariate plot of the length (L) and with (W) of the M1 of Neogene martens. The linear regression a' (r2 = 0.73) is defined by relatively hypercarnivorous martens, characterized by short M1 talon and comprise Circamustela spp., and Sinictis. The linear regression b' (r2 = 0.75) is defined by more generalist taxa, characterized by longer M1 talon, comprising Pekania Gray, 1865, Paramartes Kretzoi, 1952 and Martes Pinel, 1792. The values are given in mm. Abbreviations: r2, coefficient of determination. M1s pictures are showed scaled between them.
