This gives a whole new meaning to being “cool”.
The most fearsome predator ever to walk the Earth, Tyrannosaurus rex was similar to a “air” out of her head, allowing it to stay cool, according to a new study.
The giant dinosaur had two large holes in the roof of the skull (dorsotemporal fenestra), which are filled with muscle-to the aid of the jaw movements of the body. But a University of Missouri anatomy professor Casey Holliday said that he was intrigued by the unusual function, which in turn he will look into it.
To that end, he and a team of researchers used thermal imaging to the modern crocodiles, in a park, in the Florida keys.

THE NEW 168-MILLION-YEAR-OLD STEGOSAURUS SPECIES, RATHER THAN BY THE SCIENTISTS
“It’s really weird to have a muscle in order to get out of the challenge to create a 90-degree turn, and go through the roof in the place of a skull,” will be Provided, and the study’s lead author, told Fox News in an e-mail. “But we have a lot of evidence for blood vessels in this area, and based on our work with crocodiles and other reptiles.”
The researchers found that when they are trying to make it on to warm it up, and there are hot spots in the roof of their skulls, which show that an increase in temperature.
“An alligator, the temperature of the body is dependent on its environment,” said one of the study’s co-authors, who Know a Distance, in a statement.”Therefore, we’ve found, when it was cooler out, and you try to warm up with our thermal-imaging revealed a large “hot spots” in the holes at the top of their skull, which is an increase of the temperature. Later in the day, when the weather gets warmer, the holes appear dark as they had been turned off in order to stay cool. This is in accordance with the foregoing, the evidence is that you have to have a cross-current circulation of blood, or an internal thermostat, so to speak.”
Larry Witmer, one of the other co-authors, said that, like the T. rex, you have to have the holes at the top of their skull, which are filled with blood vessels.
And yet, for more than 100 years, we have chosen the groups in a similar space, with the dinosaurs,” Witmer added. “Through the use of some basic anatomy and physiology of modern animals, we can demonstrate that we are able to tip over that first set of hypotheses about the anatomy of this part of the T. rex skull.”
