Asset Overview

This model of an adult *Tyrannosaurus rex* shows the 3D orientations and magnitudes of the different jaw muscles. In the background is a ternary plot that shows these orientations in 2 dimensions. Appreciate how most of the jaw muscles are oriented vertically in T. rex highlighting how optimized this animal is for delivering enormous bite forces (near 60kN) through its robust skull and bone-cracking teeth.
