Mamenchisauridae is an extinct family of sauropod dinosaurs. The family was first named by Chinese paleontologists C.C. Young and H.C. Chao in 1972, in a paper describing Mamenchisaurus.[1] Other mamenchisaurids may include Bellusaurus, Chuanjiesaurus, Eomamenchisaurus, Hudiesaurus, Klamelisaurus, Omeisaurus, and Tonganosaurus. Fossils of Mamenchisaurus and Omeisaurus have been found in the Shangshaximiao Formation, dating to the Oxfordian stage, around 161.2-155.7 Ma (million years ago). Chuanjiesaurus fossils date between 175.6-161.2 Ma, while those of Eomamenchisaurus were found in the Zhanghe Formation, believed to be around 175.6-161.2 million years old.[2] Fossils of Tonganosaurus date to even earlier, from the Early Jurassic.[3]
