Sternum anteriorly similar to Menura, but not so concave on its lower horizontal 

 plane ; posteriorly it differs very much, being not so convex, broader, and with two 

 very deep fissures on each side ; the central portion of the margin is also straight ; 

 keel similar. 



The pelvinal bones were completely destroyed. 



Bibs and metatarsi similar to Menura. 



Furculum similar to Menura, but with a very slight notch at its junction with the
