The Real Big Bird

Remains of Giant Dinosaur Found in China - The Huffington Post: "BEIJING — The remains of a giant, birdlike dinosaur as tall as the formidable tyrannosaur have been found in China, a surprising discovery that indicates a more complicated evolutionary process for birds than originally thought, scientists said Wednesday.

Fossilized bones uncovered in the Erlian Basin of northern China's Inner Mongolia region show that the specimen was about 26 feet long, 16 feet tall and weighed 3,000 pounds, said Xu Xing, a paleontologist at the Institute of Vertebrate Paleontology & Paleoanthropology in Beijing.

The height is comparable to the meat-eating tyrannosaurs. But the dinosaur, called Gigantoraptor erlianensis, also had a beak and slender legs and likely had feathers. It was 35 times larger than its likely close relation, the Caudiperyx, a small, feathered dinosaur species, Xu said.

That puts the Gigantoraptor's existence at odds with prevailing theories that dinosaurs became smaller as they evolved into birds and that bigger dinosaurs had less birdlike characteristics, he said..."
