_Composition of the Brontosaurus Skeleton._ "The principal specimen,
No. 460, is from the Nine Mile Crossing of the Little Medicine Bow
River, Wyoming. It consists of the 5th, 6th, and 8th to 13th cervical
vertebrae, 1st to 9th dorsal and 3rd to 19th caudal vertebrae, all the
ribs, both coracoids, parts of sacrum and ilia, both ischia and pubes,
left femur and astragalus, and part of left fibula. The backbone and
most of the neck of this specimen were found articulated together in
the quarry, the ribs of one side in position, the remainder of the
bones scattered around them, and some of the tail bones weathered out
on the surface.
"From No. 222, found at Como Bluffs, Wyo., were supplied the right
scapula, 10th dorsal vertebra, and right femur and tibia.
"No. 339, from Bone-Cabin Quarry, Wyoming, supplied the 20th to 40th
caudal vertebrae, No. 592, from the same locality the metatarsals of
the right hind foot; and a few toe bones are supplied from other
specimens.

Quarry, north of Medicine Bow, Wyoming.]
"The remainder of the skeleton is modelled in plaster, the scapula,
humerus, radius and ulna from the skeleton in the Yale Museum, the
rest principally from specimens in our own collections. The modelling
of the skull is based partly upon specimens in the Yale Museum, but
principally upon the complete skull of Morosaurus shown in another
case.
