If a controversial new study is right, famous fossils such as Sue and Stan aren’t T. rex after all. But leading experts are highly skeptical.
“More specimens are always really helpful. And it’s possible that some of theT. rexfossils in museums already are actually from a different species. And we just haven’t noticed the right trait yet,” says Napoli. “The issue of understanding variation inT. rex, or any othe...
The evidence comes from the unearthing of a new tyrannosaur species in northeastern China that lived 60 million years before T. rex. The fossil record preserved remains of fluffy down, making it the largest feathered dinosaur ever found. If a T. rex relative had feathers, why not T. rex?
Siats is part of the carcharodontosaurid dinosaur group, containing a couple of the largest known predatory dinosaurs. At this time, Carcharadontosaurs were the top predators. So imagine a world where the giant Siats is top dog, and ancestors of the T. rex (tyrannosaurs) about the size o...
Many species of abelisaurs had front limbs that were even shorter than those of the more famousTyrannosaurus rexandeffectively useless. This would have left abelisaurid hands unable to grasp, forcing the dinosaurs to rely on their powerful heads and jaws to capture prey. ...

The age of dinosaurs wasn’t conducted solely above ground. A newly discovered ancestor ofThescelosaurusreveals that these animals spent part of their time in underground burrows. This newspeciesadds to our understanding of life during the mid-Cretaceous, both above and below ground. ...
Its name comes not from its ferocity or its kinship withT. rex, but from an unusual prominent nasal crest on its head, which probably was an ornament for sexual or species selection. Such crests have not been seen before in a tyrannosaur. ...
A new species of pterosaur has been discovered on the Isle of Skye in Scotland. The winged reptile, named Ceoptera evansae, lived between 168 to 166 million years ago during the Middle Jurassic period when dinosaurs roamed the Earth.
Professor Paul Barrett, merit researcher at the Natural History Museum, said the discovery of the new species was a "complete surprise" because "most of its close relatives are from China".
