FIGURE 3 in Geographic and temporal variability in Pleistocene lion-like felids: Implications for their evolution and taxonomy

FIGURE 3. Profile depths (blue) and angular variables (red) measured on lion crania. Angle A: the cranial profile angle (nasale–frontale angularity), angle B: the angle between narial aperture and nasofrontal profile (premaxillary– nasofrontale angularity), and angle C: the angle between alveolar margin and postorbital process (maxillary–frontale angularity). Cranium drawing modified according to Argant (1991).
