OSTEOLOGY OF THE ARMORED DINOSAURIA. 



evidence for the association of the scattered parts of various individuals is graphs 

 ically portrayed to the reader. Articulated and otherwise closely associated ele- 

 ments, where there is reason for believing they pertain to one individual, are given 

 a single catalogue number. In some few instances quite widely separated bones 

 have been thus catalogued on the evidence, as in the case of limb bones representing 

 opposite sides and of the same dimensions, same degree of rugoseness of the points 

 of muscular insertion, and of the articular ends, etc. This procedure has in some 

 cases probably resulted in a wrong association of parts, but the verification of these 

 determinations can now be readily made by any future student. 



The following tables give the bones found in Quarry 13, and are arranged 

 according to the diagrams shown in fig. 2.
