The fossilised remains of a giant bird-like dinosaur have been
uncovered in the region of Inner Mongolia, China.
While some have theorised that meat-eating dinosaurs got smaller
as they evolved to be more bird-like, this beast weighed about
That is about 35 times heavier than other similar feathered
Nature journal reports that the beaked animal was 8m (26ft) long

The authors suggest the dinosaur's enormous size was due to a
fast growth rate, faster even than the precocious Tyrannosaurus

Gigantoraptor erlianensis had some features associated with
meat-eating dinosaurs, such as sharp claws for tearing flesh; but it
also had some features associated with plant-eaters, such as a small
head and long neck.
Chinese researchers uncovered the fossilised remains of the
flightless giant in the Erlian basin in Inner Mongolia.
