Jintasaurus (Chinese: Jin Ta Long ; pinyin: Jinta long) is a genus of hadrosauriform dinosaur described by Hai-Lu You (You Hai Lu , You Hailu) and Da-Qing Li (Li Da Qing , Li Daqing) in 2009. The type species is J. meniscus. Jintasaurus lived during the Early Cretaceous of what is now Gansu, northwestern China. The fossils were discovered in Jinta County, Jiuquan, Gansu, China. The discovery supports the theory that hadrosaurs originated in Asia. The holotype and only known specimen includes the postorbital skull, lacking the jugal and quadratojugal.
