Meniscoessus major CALCANEUM

A large calcaneum, AMNH 77264, is referable to Meniscoessus (fig. 12L). The specimen is incomplete, because it lacks most of the shaft. The calcaneum is robust, and the convex posterior articular facet is large. The sustentaculum is subrounded with a flat articulating surface, and is connected to the concave, rounded depression of the cuboid facet by a broad bridge. The foramen nutriens is present on both calcanea recovered from the Judith River Formation, proximal to the cuboid facet, ventral to the sustentaculum, and lateral to the bridge connecting these facets.
