Scientists have discovered a new species of stegosaur that is the most ancient of the group of armoured herbivorous dinosaurs unearthed in Asia, and could be the oldest in the world.
The previously unknown species, Bashanosaurus primitivus, roamed the planet about 168 million years ago, and its new fossil sheds more light on the origin and evolution of stegosaurs – one of the most easily recognisable types of dinosaurs with their huge back plates, long tail spikes and tiny head.
