Researchers have discovered a new species of giant, bird-like dinosaur that made nests larger than monster truck tires in what is now central China, a study said.
Measuring about eight metres (26 feet) long and weighing up to 3,000 kilograms (6,600 pounds), the Beibeilong sinensis -- "baby dragon from China" -- lived about 90 million years ago and is only the second known species of the giant oviraptorosaur in the world.
