Camarasaurus annae (Ellinger, 1950), a little-known specimen stored in the "big bone room" in the basement of the CMNH, shows a remarkably well-preserved cervico-dorsal series. The vertebrae fit together well, and provide futher evidence that the ostelogically neutral pose (ONP) is quite straight in the transition from back to neck.
