off from the ridge, but is not bent so strongly forwards as in many 

 other Triassic Theropoda. The caput humeri lies on the medial angle 

 and is posteriorly thickened; the highest part of the upper border 

 is similarly thickened. The distal end is broad and has its condyles 

 directed strongly forwards. 



The first metacarpal is an extraordinarily compact broad short 

 bone. The proximal surface is triangular. 



The ilium has a sharp but short anterior process; the spina 

 posterior is long and moderately broad. The upper surface is bent 

 inwards in the middle. The ridge above the acetabulum is not so 

 roof-like as in many other genera. The crista interior on the inner 

 side of the posterior process is not very prominent. 



The middle and the distal end of the pubis is broadened and thin, 

 the lateral and distal edges being thickened. 



The femur is slender and lightly bent from front to back. The 

 tibia has its distal end compressed from front to back, while the 

 proximal end is convex medially and has a large tuberosity laterally. 

 The anterior process is somewhat bluntly rounded. On each side 

 of the tuberosity the lateral edge is hollowed out. 



Von Huene separates the genus from Plateosaurus on account of 

 its Thecodontosaurus-Yike tibia. The scapula, ilium, pubis, femur and 

 hand are more strongly built than in Thecodontosaurus.

In his original description Broom says ''This Dinosaur resembles 

 Massospondylus carinatus sufficiently closely to suggest the advisability 

 of placing it at least provisionally in the same genus. The remains 

 consist of an imperfect humerus, a nearly perfect radius and ulna, 

 and a perfect manus, as well as portions of the femur and tibia, 

 and a number of toe bones all of one individual, and the perfect 

 pes of another individual." 



Re-examination shows that the remains supposed to constitute the 

 first individual really contain two individuals. The supposed femur 

 is in reality the distal half of a humerus, larger than that belonging
