Asiatosaurus (pronounced AYE-see-at-tuh-SAWR-us) (meaning “Asian lizard”) was a genus of herbivorous sauropod dinosaur which lived during the early Cretaceous. Its fossils have been found in China and Mongolia. It is known only from teeth, making it difficult to rely on information until more specimens are found to expand our knowledge.
The type species, A. mongolensis, was described by Osborn, in 1924. A. kwangshiensis was described by Hou, Yeh and Zhao, in 1975 based on teeth from the Napai Formation of Guangxi, China. Both are now classified as nomina dubia or are considered questionable and considered a senior synonym Chiayusaurus.

This sauropod reached approximately 20 meters in length and weighted up to 13 tons.
