A. Cross-section of the second segment from the posterior end. The medial side (right in image) is highly eroded (maximum dimension equals 12.4 cm). B. Closer view of cortical bone and transition to spongy inner bone. Note aligned, longitudinal vascular canals in the cortical bone. C. Closer view of spongy bone, showing numerous, irregularly spaced vacuities, exterior towards the upper left corner. Note that the vacuities are larger towards the interior.
