The dimensions of the manus are taken from two individuals, one of 
which, No. 15,158, is a very young animal with metacarpal epiphyses still 
separate.

The pelvis is not sufficiently well preserved in any of the specimens to 
render satisfactory measurements practicable, and in the most complete 
skeleton (15,131) the bones of the hind leg and foot are all more or less 
injured and distorted, so that measurements of other individuals are added 
for comparison.
