Xixiasaurus is a genus of troodontid dinosaur described in 2010. The type species is X. henanensis. Fossils of Xixiasaurus were discovered in central China, in the Majiacun Formation of Henan, and are believed to have been from the Late Cretaceous (Coniacian-Campanian age, about 83 Ma ago). The fossils were described by a team of Chinese scientists composed of a group from the Chinese Academy of Geological Sciences in Beijing and a second group from the Henan Geological Museum in Henan.[1]
