The T-Rex has been the badass of the dinosaurs for as long as I can remember. In recent years however they have come under attack from stupid idiots who said that they were nothing more than giant scavengers and weren’t that badass at all. Thank god a new study has been released that gives good ol’ Rexy a little ego boost. The study found that the T-Rex had a much stronger bite fore than previously thought, stronger than any other animal in the history of the world. So fuck you sharks and crocodiles, you pussies.
Previous estimates of the prehistoric predator’s bite suggested it was much more modest – comparable to modern predators such as alligators.
This measurement, based on a laser scan of a T. rex skull, showed that its bite was equivalent to three tonnes – about the weight of an elephant.
The findings are published in the journal Biology Letters.
Dr Karl Bates from the biomechanics laboratory at the University of Liverpool led the research.
He and his colleague, Peter Falkingham from the University of Manchester, used the life-sized copy of a T. rex skeleton exhibited at Manchester Museum as a model for their study. “We digitised the skull with a laser scanner, so we had a 3-D model of the skull on our computer,” Dr Bates explained.
“Then we could map the muscles onto that skull.”
The scientists then reproduced the full force of a bite by activating the muscles to contract fully – snapping the digital jaws shut.
“Those [simulated] muscles closed the jaw as they would in life and… we measured the force when the teeth hit each other,” Dr Bates explained to BBC Nature.
“The maximum forces we found – up at the [back] teeth – were between 30,000 and 60,000 Newtons,” he said.
“That’s equivalent to a medium-sized elephant sitting on you.”
Previous studies had estimated that T. rex’s bite had a force of 8,000-13,000 Newtons.
