T-Rex – Science Says Its Bite Was A Monster

The movie world of Jurassic Park isn’t quite “historically accurate.” Um Dave, it-s-a-movie!  Stay with me, we are going someplace.

The Jurassic time period occurred from 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period.   The Cretaceous Period lasted approximately 79 million years and it was in the later part of that period that saw the rise of the awesome T-Rex.  The tyrant lizard, king of the dinosaurs, stood 13 feet tall at the hips, 40 feet long and weighing as much as 9 tons.

This marvelous monster has been the subject of many myths but now Popular Science has determined just how powerful the Tyrannosaurus Rex’s bite really was.

Researchers say that a single T. Rex bite used about 8,000 pounds of force.  Using computer models and the bite metrics of modern day alligators and crocodiles scientists came up with a ridiculous number – 431,342 pounds per square inch at the tips of giant, sharp, serrated teeth.

For some perspective, a hydraulic press used to crush cars uses about 2,000 P-S-I.  Cars didn’t come along until Karl Benz gas powered model in 1844 and it didn’t bite!
