FIGURE 1 in Craniocervical feeding dynamics of Tyrannosaurus rex

FIGURE 1. Anatomical and inertial reconstructions used for calculating neck dynamics of Tyrannosaurus rex. A, Superficially visible neck muscles mapped onto a skeleton of Tyrannosaurus rex AMNH 5027 (BMR cast), with the head and neck lateroflexed to the left. Insertions of M. transversospinalis cervicis onto anterior epipophyses are posteroventral to the origins of M. complexus from the same structures. B–D, 3-D computer representation of Tyrannosaurus rex (AMNH 5027) used to calculate gravitational moments and rotational inertias, in dorsal (B), lateral (C), and anterior (D) views. The skeleton is superimposed on the model in B; congruence is not absolute because the 3-D models are rendered in strict orthogonal view and the skeleton in perspective view.
