Fig. 6. Illustration of the foot rotation in typotherian notoungulates. Schematic anterior view of the ankle of a plantigrade (A) and digitigrade (B) mammal. Colbertia lumbrerense PVL 6227 (C), Typotheria indet. PVL 4292 (D), and "Campanorco inauguralis" IBIGEO-P 105 (E) in anterior view. The colored lines represent the hypothetical tibia long axis (black line), mediolateral axis of the astragalar head (blue line), the plane of the trochlear crests (red line), and the hypothetical metatarsal plane (green line).
