Tsintaosaurus (/sIntaU’so:r@sor “Qingdao lizard”, after the transliteration of “Tsingtao”) is a species of hadrosaurid dinosaurs that came that was found in China. It was 8.3 meters (27 feet) long and was weighed 2.5 tonnes. The species of interest is Tsintaosaurus spinorhinus first described by Chinese paleontologist C. C. Young in 1958.

Hadrosaurs, Tsintaosaurus was distinguished by its snout with a ‘duck bill’ and a set of strong teeth utilized to eat plants. It typically walked on all fours, however, it could raise its hind legs in order to search for predators. It would flee if it saw one. Similar to other hadrosaurs Tsintaosaurus likely existed in herds.

In 1950, in Hsikou close to Chingkangkou located situated in Laiyang, Shandong, in the eastern region of China numerous fossils from large hadrosaurids was discovered. In 1958, they were identified in the work of Chinese paleontologist Yang Zhongjian (“C.C. Young”) as the species that was the prototype Tsintaosaurus spinorhinus. The name itself originates from the Chinese city Qingdao which was previously translated as “Tsintao”. The exact meaning is “with a nose spine” and is derived which comes from Latin spina and Greek Ris”nose” or rhis “nose”, in reference to the distinctive crest of the snout.

The Holotype, IVPP AS V725, has been found in a layer from the Jingangkou Formation that is one of the Wangshi Group, dating back to the Campanian. It is composed of a part of a skull and skeleton. The specimen is IVPP V818, which is a skull roof. Within the same region, other partial skeletons, as well as numerous bones that were disarticulated were discovered. A few of them were named by Yang who was referred to as Tsintaosaurus Others were described as Tanius Chingkankouensis Yang 1958, and the Tanius laiyangensis Zhen 1976 is known. The two species mentioned above are currently classified as junior synonyms or nomina dubia. The researchers of the future would assign more of the evidence to Tsintaosaurus.
