Stress distributions in scaled models for neck muscle driven bites.

<p>Von Mises (VM) stress distributions and mean landmark point VM stresses given respectively for (A & D) <i>Smilodon fatalis</i>, (B & E) <i>Thylacosmilus atrox</i>, (C & F) <i>Panthera pardus.</i> MPa = Megapascals. Muscle forces scaled to bite reaction forces predicted on the basis of body mass.
