Plate VII. Vertebral column of Barosaurus lentus compared with that of Diplodocus 
camegiei, the latter after Hatcher 1901, Plate XIII. About one twenty-fifth 
natural size. The scapula of Barosaurus is slightly in advance of that of 
Diplodocus. The dorsal series of Barosaurus is slightly longer, the caudals 
much shorter, and with lower spines, while the four cervicals preserved are 
nearly equivalent in length to six of the posterior neck bones of Diplodocus. 
Of the femur, pubis, and ischium of Barosaurus, the portions preserved are 
indicated with their much greater relative bulk. Of the ilium, but the pubic 
peduncle and portions of the rim are recognizable; its size and shape therefore 
are conjectural. The preserved portion of the right scapula is indicated. No 
single rib is preserved in its entire length, so the volume of the torso could 
not be estimated. It is probable that the neck may have had an upward 
flexure, especially between cervical XV and the first dorsal and between the 
first and second dorsals, as its habitual posture. This is not, however, indicated 
as it would make the relative comparison with Diplodocus less emphatic.
