FIGURE 73 in Osteology of Tyrannosaurus rex: insights from a nearly complete skeleton and high-resolution computed tomographic analysis of the skull

FIGURE 73. FMNH PR2081, Tyrannosaurus rex. Pathological costal features. A, Right p10, with large anterolateral sequestrium. B, Right?p13, lateral view. This is all that was preserved, and this is not shown in the rib plates (Figs. 64, 65); note large extostotic mass at termination. It is not known if this is the proximal or distal half of the fracture zone. C, Left p18, with large sequestrium on posterior surface of shaft and acute process distal to head. Scale for A-C = 5 cm. D, Right lateral view of FMNH PR2081 as mounted, showing several rib pathologies (including those shown in A and B) and the pathological right scapulocoracoid and humerus occurring within a discrete region of the skeleton.
