A gigantic bird-like dinosaur weighing as much as a car towered over its relatives about 70 million years ago, a new finding suggests.
Chinese scientists unearthed the skeletal remains of the dinosaur, now named Gigantoraptor erlianensis, in the Erlian Basin of Inner Mongolia, China.
The unearthed beaked dinosaur was not full-grown, yet it tipped the scals at more than 3,000 pounds. Paleontologists who discovered its remains estimate the behemoth was just 11 years old when it perished.
At up to 16 feet tall and 26 feet long, Gigantoraptor dwarfed its relatives, a group of small, feathered theropods called Oviraptorosaurs. The hefty dinosaur weighed 35 times more than other Oviraptorosaurs.
In addition to its size, Gigantoraptor sported several bird-like features, such as a longer arm and more avian-like leg, not present in its relatives. The scientists say this finding sheds light on theropod (two-legged carnivorous dinosaurs) evolution leading to the emergence of birds.
