Fig. 4 in Endocranium and ecology of Eurotherium theriodis, a European hyaenodont mammal from the Lutetian

Fig. 4. Schematic evolution through time of the size of the endocast of several hyaenodonts. Red, lateral sulcus; green, suprasylvia; blue, ectosylvia. Endocast morphology has been modified from Radinsky (1977) except that of Proviverra typica Rütimeyer, 1862 (Dubied et al. 2019a) and Eurotherium theriodis (Van Valen, 1965) (present paper). The endocasts are not to scale. The phylogenetic relationships are based on Solé et al. (2020).
