the femur is slender and thin-walled. the proximal portion possessed early dinosaurian hallmarks such as an anterior trochanter, a facies articularis antitrochanterica, well-developed medial tubera separated by a deep ligament sulcus, and an asymmetrical and pronounced fourth trochanter. the femoral head also possessed a deep and curved groove, but the appearance of this groove is known to be variable within some dinosaur species, so it is not particularly informative for "nhandumirim"'s classification. the trochanteric shelf was not present, but a homologous muscle attachment scar did exist in the same area, along with a more proximally-located anterolateral scar similar to that reported in some silesaurids. unlike other early dinosaurs, the dorsolateral trochanter was characteristically short, ending quite a distance away from the femoral head like the anterior trochanter. the distal portion had a wide medial condyle and muscle scars similar to those of "herrerasaurus".
