![]() Tyrannosaurus rex was also adept at finding its prey thanks to a keen sense of smell. To keep itself from overheating while crushing prey with its mighty jaws, the giant animal had vents in its head to help its brain stay cool, similar to those found in alligators. This dinosaur used its 60 serrated teeth, each about eight inches long, to pierce and grip flesh, throwing prey into the air and swallowing it whole. This fierce carnivore was optimally built for crunching through its meals, with a stiff skull that allowed it to channel all the force of its muscles into one bite- delivering up to six tons of pressure. These dinosaurs likely preyed on living animals and scavenged carcasses-and sometimes they even ate one another. rex stomped headfirst across its territory on two strong legs. This dinosaur’s muscular body stretched as long as 40 feet-about the size of a school bus-from its snout to the tip of its powerful tail. Tyrannosaurus rex, whose name means “ king of the tyrant lizards,” was built to rule. Improved technologies, such as biomechanical modeling and x-ray imaging, have allowed scientists to gain a deeper understanding of how this apex predator lived. rex is a household name, what we know about this tyrannosaur is constantly evolving. With a massive body, sharp teeth, and jaws so powerful they could crush a car, this famous carnivore dominated the forested river valleys in western North America during the late Cretaceous period, 68 million years ago.Īlthough T.

This specimen may not be headed to a research institution, though. Marks on the skull are interesting to study “because they give us an idea about what life was like during the Cretaceous period,” Hatton said. “We don’t know that this is what caused the death of this animal, but we can tell that it did have a major battle during its lifetime,” she said. Hatton said two large puncture holes in the skull are evidence of a big fight, probably with another T. The 6 1/2-foot (2-meter) fossil is about 76 million years old and still has most of the external skull bones and numerous teeth, Sotheby’s experts said. Hatton noted, “When you think about it, more people can fit a skull in their home than people who could fit a full dinosaur.” rex’s remains were destroyed over time by erosion, but Sotheby’s experts said the skull was a major find. She called the area “the world capital for T. rex skeletons like Sue and Stan were found, according to Cassandra Hatton, Sotheby’s head of science and popular culture. ![]() The skull was excavated in 20 in Harding County, South Dakota, where other T. 9 by an owner who wishes to remain anonymous, the auction house said. ![]() The 200-pound (91-kilogram) skull fossil, nicknamed Maximus, is being sold Dec.
