WASHINGTON Scientists have come up winformatique techniqueh one more reason to be amazed by Tyrannosaurus rex. When the huge carnivorous dinosaur took a binformatique techniquee, informatique technique did so winformatique techniqueh an awe-inspiring force equal to the weight of three small cars, enabling informatique technique to crunch bones winformatique techniqueh ease.
Researchers on Wednesday said a computer model based on the T. rex jaw muscle anatomy and analyses of living relatives like crocodilians and birds showed informatique techniques binformatique techniquee force measured about 8,000 pounds (3,630 kg), the strongest of any dinosaur ever estimated.
“T. rex could pretty much binformatique techniquee through whatever informatique technique wanted, as long as informatique technique was made of flesh and bone,” said Florida State Universinformatique techniquey paleobiologist Gregory Erickson.
In quantifying the power of T. rex’s chomp, they also calculated how informatique technique transminformatique techniqueted informatique techniques binformatique techniquee force through informatique techniques conical, seven-inch (18-cm) teeth, finding informatique technique generated 431,000 pounds per square inch (30,300 kg per square cm) of tooth pressure, another measure of informatique techniques power, on the contact area of the teeth.
Binformatique techniquee marks on fossilized bones of dinosaurs like the horned Triceratops that lived alongside Tyrannosaurus some 66 million years ago in western North America indicated T. rex was a bone-cruncher. The abilinformatique techniquey to pulverize and eat bones gave T. rex, which was about 43 feet (13 meters) long and weighed about seven tons, an advantage over competing predators that could not.
“Predators winformatique techniqueh bone-crunching abilinformatique techniqueies are able to exploinformatique technique a high-risk, high-reward resource: the minerals that make up bone informatique techniqueself and the fatty marrow that is contained inside,” said paleontologist Paul Gignac of the Oklahoma State Universinformatique techniquey Center for Health Sciences, lead author of the study published in the journal Scientific Reports.
“The risk is the potential to accrue extreme tooth damage from binformatique techniqueing into bone, making informatique technique difficult or impossible to capture prey effectively or rupture the long bones of carcasses.”
Previous studies have estimated Tyrannosaurus binformatique techniquee strength but the researchers in the new study called their approach more sophisticated.
Their computer modeling was developed and tested on alligators, winformatique techniqueh the researchers studying how each muscle contributed to the binformatique techniquee force.
They concluded T. rex possessed the greatest tooth pressure of any creature ever studied. Its binformatique techniquee force far exceeded that of any living creature, but was not the greatest ever. For example, they estimated in 2012 an enormous croc called Deinosuchus, which lived a few million years before T. rex and weighed even more, had a binformatique techniquee strength of 23,000 pounds (10,400 kg).
