Utuntu dushimishije
Xuanhanosaurus had a forearm that was relatively massive and long, which is unusual for a meat-eating dinosaur of its time.1
Its humerus, the upper arm bone, was straight and had a medial deltopectoral crest, a feature that helped attach strong muscles.1
The ratio of the maximum length of its humerus to its radius was 1.3, which scientists say is extremely conservative for a carnosaur.1
Xuanhanosaurus had a metacarpal III that was comparatively massive, and its metacarpal IV was short and light.1
The fossils come from the Lower Shaximiao Formation, which is Middle Jurassic in age, about 170 to 168 million years old.2
