Figure 10.13 in Looking again at the forelimb of Tyrannosaurus rex
Figure 10.13. Deformation of a crocodilian and avian scapula and coracoid (SC) to approximate that of Tyrannosaurus. Wavy vertical lines show direction and degree of morphing. This method allows for the prediction of the position and shape of various muscles on the Tyrannosaurus SC (see text). (A) Tyrannosaurus scapula-coracoid used as the end point to morphing of the (B) crocodilian and (E) avian pectoral girdles. Note that 2 possible scenarios (C, D) occur in the morphing of the crocodilian SC depending on what portions of the crocodilian scapula is morphed into the acromion process of the Tyrannosaurus scapula. Location of actual muscle scars (G). Abbreviations: bb, M. biceps (continued) brachii; c-M. costocoracoideus; cbd, M. coracobrachialis brevis dorsalis; cbv, M. coracobrachialis brevis ventralis; ce, M. coracobrachialis externus; ch, M. coracohumeralis; dc, M. deltoideus clavicularis; ds, M. deltoideus scapularis; I, M. levator scapulae; rs, M. rhomboideus superficialis; sb, M. supracoracoideus brevis; sc, M. scapulohumeralis cranialis; scd, scapulohumeralis caudalis; se, M. subscapularis externus; si, M. supracoracoideus intermedius; svc, M. subscapularis ventralis cranialis; svt, M. serratus ventralis thoracis; t, M. trapezius; tbclps, M. triceps brachii; caput longus pars scapularis; tll, M. triceps longus lateralis; tm, M. terres major. Figure (B) and terminology adapted from Meers (2003); figure (E) and terminology adapted from Yasuda (2002). Although the terminology is retained for "dorsal" versus "ventral" muscles (e.g., m.c.b. ventralis), the more vertical position of the humerus in Tyrannosaurus indicates a need for modified terminology.

Figure 10.18. Comparison of forelimb length to hind limb length shows that a progressive reduction in forelimb length does not occur in the Tyrannosauridae. Abbreviations: Gu, Guanlong (basal tyrannosauroid); Go, Gorgosaurus; Da, Daspletosaurus; Ab, Albertosaurus; T, Tyrannosaurus.
Figure 10.9 in Looking again at the forelimb of Tyrannosaurus rex
Figure 10.9. Muscle maps for humerus in Tyrannosaurus, Alligator, and Gallus. Top row is anterior, bottom row is posterior. Muscle map based on scars (A, F) Tyrannosaurus. Map for Alligator (B, G) and predicted for Tyrannosaurus (C, D) based on deformation of Alligator humerus. Map for Gallus (D, I) and predicted for Tyrannosaurus (E, J) based on deformation of Gallus humerus. Note that predicted scars for deformed Alligator (C, H) are a better match for the scars of Tyrannosaurus (A, F). This prediction is also supported by the pattern of avulsion seen in a Tyrannosaurus humerus (K, L). See Figure 10.13 and text for further explanation.
Figure 10.7 in Looking again at the forelimb of Tyrannosaurus rex
Figure 10.7. Partial collapse of the glenoid in DMNH 2827 as seen in lateral view (A), with close-up (B); in medial view (C), with close-up (D); and ventral view showing the telescoping that occurred between the arrows. Sclerotic bone overhangs the lateral surface. The amount of deformation decreases dorsally to about the level of the coracoid foremen and indicates a posteroventral rotation of the coracoid due to great stress.
Figure 10.5 in Looking again at the forelimb of Tyrannosaurus rex
Figure 10.5. Evidence for stress fracture in the furcula of TCM 2001.90.1 is the prominent callus (A), seen clearly in dorsal view (B) and in close-up showing periosteal reactive bone (C). The region is X-ray opaque because of the greater deposit of bone (D, between arrows). Scale for A in centimeters.
Figure 10.3 in Looking again at the forelimb of Tyrannosaurus rex
Figure 10.3. Close-up of the epicleidial facet (arrow) on the dorsal edge of the scapula DMNH 2827 (A) and lateral view with the furcula articulated (B).

Figure 10.1. Comparison of maximum forelimb motion in 3 well-known theropods. None of the dinosaurs can reach its manus to its mouth as a result of constraints in the shoulder (see Carpenter 2002). Note that Tyrannosaurus has the greatest range or retraction. Not to scale.

Figure 3 in Mosaic patterns of homoplasy accompany the parallel evolution of suspensory adaptations in the forelimb of tree sloths (Folivora: Xenarthra)
Figure 3. Boxplots and ancestral state reconstructions of select linear measurements and angles. Metrics were selected to represent the diversity of observed outcomes, including one example (A) of a trait that is clearly distinct between tree sloths and other taxa, one example (B) of a trait that exhibits significant convergence between tree sloths but not a significant difference between tree sloths and other xenarthrans, and one example (C) of a trait for which tree sloths do exhibit a significant difference with other xenarthrans, but do not exhibit clear evidence of convergence. Ancestral state reconstructions are provided to visualize changes in a phylogenetic context and are not necessarily intended to accurately characterize ancestral states, although they do represent the states used to measure convergence. In the heatmaps, purple represents the direction predicted for suspensory taxa.
