Pinacosaurus grangeri

About 80 million years ago, during the Late Cretaceous, this armored plant-eater roamed the Gobi Desert in Central Asia. Pinacosaurus is related to Ankylosaurus, an armored dinosaur that lived in North America about the same time. Both dinosaurs could whack enemies with their tail clubs.
