Eighth Dorsal Vertebra. 
Unfortunately no specimen of the eighth dorsal was found in any of the 
material collected except the centrum of a large 
and fully adult specimen which has received the 
Catalogue Number 1731. This was associated 
with the centra of the 9th and 10th dorsals of 
the same individual. The specimens came from 
Quarry No. 2 and were found by Mr. Utterback 
as surface fragments lying close together. This 
centrum has been employed in reproducing the 
eighth dorsal in the mounted specimen. The 
spine, the postzygapophyses, and the transverse 
processes are modelled after the analogies of the 
seventh and ninth vertebre, of which we have well-

mation to the true form of the bone has been effected.
