Daanosaurus

Daanosaurus (meaning "Da'an lizard" after Da'an district in Zigong, Sichuan) was a genus of dinosaur. It was a brachiosaurid sauropod which lived during the Late Jurassic (Oxfordian - Tithonian stage, about 163 - 145 mya). It lived in what is now China (Sichuan Province), and was similar to Bellusaurus.[1] When it was described, Daanosaurus was placed in the Bellusaurinae, a sub-family of Brachiosauridae that Dong Zhiming had raised in 1990 to house Bellusaurus, or the Klamelisauridae (also now merged with Brachiosauridae), used to house Klamelisaurus, possibly Dannosaurus and Abrosaurus.[1][2] More recently, other authors have placed Daanosaurus in the Eusauropoda.
