the tibia was poorly preserved but did possess several features similar to those of neotheropods. these include a tall facet for the ascending process of the astragalus and a distal tip which was wide and flattened when seen from below and boxy when seen from the front. there was also a diagonal mound-like tuberosity on the anterior surface of the tibia. "nhandumirim" is the only known dinosaur to possess both these neotheropod-like traits and a diagonal tuberosity. the more complete fibula was elongated (~10% longer than the femur) and had scars for the tibial ligament and iliofibularis muscle near the knee. there was a semicircular facet for the ascending process of the astragalus on the portion of the fibula contacting the heel, a characteristic unique to "nhandumirim". metatarsal ii is straight, with a flattened proximal portion and boxy distal portion. metatarsal iv has a more irregularly-shaped distal portion but is also straight, an unusual feature more akin to "lagerpeton" and pterosaurs rather than the more curved bone of other dinosaurs. isolated phalanges are variable in proportions, with one having a wide proximal articulation and the rest having tall, triangular proximal articulations and more well-developed joint surfaces. unguals are triangular in cross section and curved, though not to the extent seen in more advanced theropods.
