Paleontologists in China have originated evidence of the largest feathered dinosaur so far. The latest species, known as Yutyrannus, has been recognized from three fossils establish in north-eastern China. The feathered meat-eating dinosaur lived concerning 125 million years ago, long before Tyrannosaurus Rex, and is predictable to have weighed a whopping 1,400kg as a grown-up, the BBC reported. The finds, complete in Nature journal, challenge present theories about the progress of Tyrannosaurus Rex and its affairs.
This cluster of dinosaurs is known as the Tyrannosauroids. Tyrannosaurus Rex and its huge cousins live until approximately 65 million years ago - when enormous asteroids wiped out the dinosaurs - but the majority of their previous relatives are consideration to have been much smaller. On the other hand, Xing Xu and generation from the Chinese Academy of Sciences in Beijing have now detailed three specimens of Yutyrannus, which represent a premature example of the Tyrannosauroid form.
The dinosaur fossils contain the one-and-a-half-ton adult and also two young specimens that would have tipped the scales at concerning half a ton. The dinosaur, whose name translates as “beautiful feathered tyrant”, shares several features with shortly tyrannosaurs like T.rex, but has three useful fingers (where T. Rex had two) and a foot characteristic of additional early tyrannosaur relatives.
Perhaps the majority notable discovery, though, is the creature’s wide plumage, which provides direct confirmation for the survival of huge feathered dinosaurs. The scientists believe the long, filament-like feathers could have acted as insulation, but they cannot rule out the opportunity that they were moreover used for display in mating or fighting rituals.
