A dinosaur that sported spine-like plates along its back is one of the earliest stegosaurs yet discovered, fossil hunters have revealed, and they say the find could shed light on the evolution of some of the most famous dinosaurs to roam Earth.
The stegosaur, which has been named Bashanosaurus primitivus in a nod to the ancient name of the region in China in which it was found in 2016 and its position on the stegosaur family tree, is thought to have lived about 168m years ago.
