Mystery ends big armed dinosaur

Scientists have solved a fifty-year old mystery surrounding one of the most peculiar dinosaurs in history.

Up to now all they had to go on was a pair of gigantic claw-tipped arms.

But the discovery of two seventy-million-year-old complete dinosaur skeletons in Mongolia, in Asia, have pieced together what the rest of the pre-historic giant looked like.

Experts say it was a massive beast with a duckbill, a huge hump and hooved feet.
