where the lower end of the tibia (shin bone) articulates with the astragalus. This surface is pierced by two fossae (small openings in bone) that have been interpreted as vascular fossae. The ascending process (protrusion of bone) is mound shaped and its upper articular surface faces proximomedially. The distal tarsals have a laterally elongated triangular shape in when seen from their top ends. The corners of the tarsals are rounded and bulbous, especially in the posteromedial corner. The medial distal tarsal is not confined solely to metatarsal III, but also barely contacts the proximal end of metatarsal II, like in Saturnalia. The lateral distal tarsal has a quadrangular shape and was likely longer mediolaterally than proximodistally. Metatarsal I is roughly 3/4 the length of metatarsal II, as in most basal sauropodomorphs. Metatarsal I has a broad and short shaft that is ellipse shaped, more so than in most other basal sauropodomorphs. The upper portion of the small posterior groove separating the two distal condyles is similar to that of Plateosaurus. The medial condyle is less robust and more proximally positioned than the lateral one. This would cause a medial displacement of the first digit, a characteristic in most saurischian dinosaurs (the group that includes sauropodomorphs and theropods). The upper end of metatarsal II is hourglass-shaped and has concave medial-lateral ends to articulate with the other metatarsals. The medial concavity is well developed, but the lateral concavity is less so. The diagnostic traits (characteristics that distinguish a taxon from others) of the second metatarsals include: a front border that is weakly convex in proximal aspect; a hypertrophied lateral plantar flange on the proximal end (present, but less developed in many basal sauropodomorphs, e.g., Saturnalia, Plateosaurus); and a medial distal condyle that is more robust and well−developed than the lateral distal condyle. The third metatarsal lacks much preserved detail, but has a trapezoidal upper end with a straight to concave front border and a slightly convex medial border for articulation with metatarsal II. The hind edge is narrower from side toside than the front one, but is not acute or rounded, causing the upper outline of metatarsal III to be almost trapezoidal, as in Lufengosaurus, Gyposaurus, and Coloradisaurus. On the contrary, most non-eusauropod sauropodomorphs have almost triangular upper outlines. Only the upper portion of the metatarsal IV is preserved, but preserves an upper outline akin to that of Lufengosaurus that has a
