WASHINGTON, Sept. 7 (Xinhua) -- The U.S. researchers found that Tyrannosaurus rex, a carnivorous dinosaur, had a built-in "air conditioner" in its skull to keep a cool head. The study published in the latest edition of the Anatomical Record showed that the two large holes at the roof ...
Using a combination of imaging, anatomy and engineering analysis, the team observed how the roof of the mouth of the T. rex reacted to the stresses and strains from chewing by applying models of how two present day relatives of T. rex—a gecko and a parrot—chew to how the T. rex s...

In the past, scientists believed two large holes in the roof of aT. rex's skull—called the dorsotemporal fenestra—were filled with muscles that assist with jaw movements. But that assertion puzzled Casey Holliday, a professor of anatomy in the MU School of Medicine and lead researcher on ...

T. RexDescription T rexwas a large, predatory dinosaur. It stood on two muscular hind legs, and had a well-built body and long, powerful tail. Its arms, in relation to the size of its body, were tiny. T Rex’s head was extremely large and heavily-built; the largestT. Rexskull is...
But when researchers analyzed a tooth from a Daspletosaurus, a T. rex relative, they found it was in good condition and it didn’t show that uneven damage pattern. With this evidence and other clues from the dinosaurs’ anatomy, the study makes a good case for lipped tyrannosaurs, said Uni...
