Judging from the one skeleton known, this dinosaur was about 8 meters (26 feet) long, from snout to tail tip, and had a weight of about 1 tonne according to Gregory S. Paul. Thomas R. Holtz Jr. estimated it at 7.6 meters (25 feet) in length and 453-907 kg (1.000-2.000 lbs) in weight. In 2016 it was given a lower estimation of 6.8 meters (22.3 feet) in length, 1.9 meters (6.2 feet) tall at the hips and 790 kg (1.742 lbs) in weight. Sereno stressed that the general build was gracile and that the forelimbs and the lower leg were relatively long: the humerus has length of forty centimetres and the tibia and fourth metatarsal measure 687 and 321 millimetres respectively, as compared to a thighbone length of seventy-six centimetres.
