(Plate XLIII; and woodcut 136, below.) The anterior caudal vertebrae of the Dinocerata have the centra short and flat, with long and depressed transverse processes. The neural spine is only moderately developed. The neural arch is low, and situated on the anterior two-thirds of the centra. The zygapophyses are weak, and their articular faces usually curved. In the median caudals, the transverse processes become shorter, and gradually disappear. The distal caudals are cylindrical, and of moderate length. They are without zygapophyses, or neural arches, as seen in figure 136, Figure 136.—Caudal vertebra of Dinoceras laticeps, Marsh (No. 1039). a. proximal end; 6. side view; c. distal end. All the figures are one-half natural size. The under surface of the caudal vertebrae is rugose, and there are no chevron Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marsh, Othniel Charles, 1831-1899.
