the inner one bears a long depression near the upper region. On the lower end, a flat articular surface can be located and is tilted forwards. Among the tarsal elements, the astragalus is the largest. It has an irregular shape with well-developed processes, and the articular surface for the fibula is shallowed. The calcaneum is square in shape and divided into four different surfaces. Among them, the upper surface articulates with the fibula and is separated from the tibial articular surface by a curved ridge-like structure. Among the metatarsus elements, metatarsal III and IV are present. The former is composed of a rather stocky shaft that has expanded upper and lower ends. Its upper articular surface is D-shaped, and the upper half of the inner surface shows a notorious depression for the articulation with metatarsal II. On the bottom surface of this metatarsal, a large ridge-like structure is present and extends along the upper two-thirds of the element. The lateral and inner surfaces of the lower end of metatarsal III are concave—mostly on the inner one—and subcircular. Metatarsal IV is fairly more slender than the previous element and its shaft is flattened from the top to bottom regions. The upper articular surface is concave and also D-shaped, with equal widened top and bottom borders. The bottom-most surface of the bone is concave and the medial one features a large tuberosity upwards to the mid-length. The lower end is nearly equally in its expansions and the articular surface is downwards convex and less concave to the lateral surface than in metatarsal III. The lateral and inner surfaces of the lower end of metatarsal IV have an oval shape and are very concave. Pedal phalanges II-1 through IV-1 are stout and show triangular-shaped and concave upper surfaces. Among the three uppermost phalanges, II-1 is the deepest. Phalanx III-1 is downwards flattened and has a subelliptical upper articular surface. Pedal phalanx II-2 is a robust element that wider than long. Its upper surface is relatively smooth and concave. The bottom border of this surface is further extended backwards in relation to the top border. Two lower phalanges belong to digit IV. These phalanges are even more flattened than phalanx II-2. Their lower and upper surfaces are similar to those of phalanx II-2, but can be differentiated in being more concave. Pedal unguals are mostly flattened and convex with elliptical upper surfaces. These elements
