The long diameter of the basis of the transverse processes of the large 
anterior caudal vertebre is directed obliquely upwards and forwards. The 
anterior faces of some of these centra are flat. 
The length of the sacrum is M. 0.900 ; elevation of first sacral rest, 0.500. 
The head of the femur is subround. One side of the shaft is damaged, 
so that the form of its section cannot be ascertained. The side of the inner 
condyle is quite flat, and without epicondylar rugosity.

The anterior and posterior edges of the scapula are thin. The posterior 
is slightly concave, with a slight projecting irregularity near the middle, 
and is then turned decidedly backwards, bounding the glenoid extremity. 
The glenoid face is concave, and longer than the coracoid suture. The 
anterior border is more strongly concave, the distal extremity being more 
expanded forwards. The sides of this extremity are slightly rugose with 
coarse grooves. The articular facets are pitted. A low keel extends along 
the external side of the mesoscapula.
