Figure 2 Limb orientation used for model Trex_1. The values of mi, the percentage of body mass as extensor muscle acting about each joint (muscle moment action shown as a red arrow) required to maintain static equilibrium at mid­stance during fast running are shown in red. Actual hindlimb bones were digitized from Tyrannosaurus specimen MOR 555 (Museum of the Rockies; Boseman, Montana).Published as part of Hutchinson, John R. & Garcia, Mariano, 2002, Tyrannosaurus was not a fast runner, pp. 1018-1021 in Nature 415 (28) on page 1019, DOI: 10.1038/4151018a, http://zenodo.org/record/372461
