T. rex was actually bigger than we thought T. rex might not have been such a hothead after all Using a combination of anatomy and engineering analysis and 3D imaging, and with the help of two of T. rex's relatives, the gecko and the parrot, the research team re-created models...
A 2021 study by Pasha A. Van Bijlert (source), which looked at the whole ofT. rex's anatomy, including its long tail, concludes that the dinosaur's walking speed was just under 3 mph / 4.83 km/h – that's about the same as a human. Back to page index DidT RexHave Feathers? To...
"It's really weird for a muscle to come up from the jaw, make a 90-degree turn, and go along the roof of the skull," said the study lead researcher Casey Holliday, professor of anatomy at University of Missouri. "Yet, we now have a lot of compelling evidence for blood vessels in ...
But that assertion puzzled Casey Holliday, a professor of anatomy in the MU School of Medicine and lead researcher on the study. "It's really weird for a muscle to come up from the jaw, make a 90-degree turn, and go along the roof of the skull," Holliday said. "Yet, we now have...

“If your arms can’t really contact prey anyway, the best way of maximizing your weapon capacity as a theropod dinosaur is actually to get rid of as much arm muscle as you can, and replace it with neck muscle,” says Habib. Stanley agrees that the arms of T. rex ancestors were basic...
