Soft tissue recently found in 68-million-year-old Tyrannosaurus rex bones is actually modern-era bacterial slime, scientists say, challenging what some call one of the most remarkable paleontology findings of the 21st century.
Learn about the seven deadliest dinosaurs in the world, from the meat-eating Tyrannosaurus rex to the plant ripper Gryposaurus monumentensi.
Big dinosaurs, like humans, reached sexual maturity during the messy growth spurts of adolescence, according to a new study.
The reproductive strategy of dinosaurs was unlike that of their reptilian ancestors or their bird descendants, the study concludes.
An extraordinarily bizarre-looking species of dinosaur has been discovered in China’s Gobi desert that could unlock clues as to how an unusual family of vegetarian dinos evolved, scientists say.
The newfound species belonged to a group of large dinosaurs called therizinosaurs, relatives of meat-eating theropods like Tyrannosaurus rex.
Today’s top athletes would be no contest for meat-eating dinosaurs that ran on two feet, according to new computer simulations of how the extinct predators moved.
Even a six-ton Tyrannosaurus rex, long considered a lumbering beast, could reach a top speed of 18 miles an hour (29 kilometers an hour), according to the simulations.
Dinosaur hunters often regale the world with news of their exotic discoveries after the fact—bones of ancient giants pulled from a hillside in Madagascar, chipped from the ice in Antarctica, dug from the pampas of Patagonia.
Now the world is invited along as a team of paleontologists excavate a Tyrannosaurus rex from the siltstone at a ranch in eastern Montana. All they need to do is log on to Unearthing T. rex.
Every few years a dinosaur leaps from the signature yellow border of National Geographic Magazine and captures the fascination of readers. This month a skull of Tyrannosaurus rex shatters a bone of its prey—another dinosaur.
Cool, but is it realistic? Is that picture with T. rex’s teeth glistening with the blood of the dinosaur it just devoured a scientifically accurate interpretation of dinnertime 75 million years ago?
