Etymology Qingdao lizard

Tsintaosaurus is a genus of hadrosaurid dinosaur from the Late Cretaceous of China. It was about 8.3 metres (27 ft) long and weighed 2.5 tonnes. The type species is Tsintaosaurus spinorhinus, first described by Chinese paleontologist C. C. Young in 1958. As a hadrosaur, Tsintaosaurus had the characteristic 'duck bill' snout and a battery of powerful teeth which it used to chew vegetation. It usually walked on all fours, but could rear up on its hind legs to scout for predators and flee when it spotted one. Like other hadrosaurs, Tsintaosaurus probably lived and traveled in herds.
