Fossil remains of a new genus of plant-eating dinosaur Bashanosaurus primitivus found in Chongqing are those of a stegosaurus that roamed the earth around 169 million years ago during the Middle Jurassic period, a scientific paper said recently. The animal is the oldest of its kind to be discovered on the continent, suggesting that stegosaurs may have originated in Asia.

The stegosaur’s remains, which included bones from the back, shoulder, thigh, feet, and ribs, as well as several armor plates, date to the Middle Jurassic period's Bajocian stage, which is much earlier than most known stegosaurs.
