Fig. 2 in Endocranium and ecology of Eurotherium theriodis, a European hyaenodont mammal from the Lutetian
Fig. 2. Digital model of Eurotherium theriodis (Van Valen, 1965), NMB Em12 (holotype) from?Egerkingen γ (Switzerland), MP13?, with in situ endocast (A2, blue). Encephalization quotient.—The encephalization quotient (EQ) is brain size divided by expected body size for an average mammal of the same body size. As a ratio, it can be used to compare brain sizes among specimens with different body masses (Bertrand et al. 2017). All the EQs herein have first been estimated using the methodology provided by Jerison (1970, 1973); this equation has previously been used to calculate the EQ of Hyaenodon and Cynohyaenodon (Jerison 1973; Radinsky 1977, 1978). The equation is: EQ = E / 0.12 P0.67; where E equals volume of the encephalon in cm3; P, body mass in grams. For the purposes of comparison, we also calculated EQ using the equation provided by Eisenberg (1981): EQ = E / 0.055 P0.74, where E is the volume of the encephalon (in cm3) and P corresponds to body mass
