}} Klamelisaurus is a genus of herbivorous sauropod dinosaur from the Middle Jurassic of China. DiscoveryThe type species Klamelisaurus gobiensis was named and described by Zhao Xijin in 1993. The generic name refers to Kelamaili, of which "Klameli" is a spelling variant, where remains were found north of Jiangjunmiao in the Junggar Basin of Xinjiang province, in 1982. The specific name refers to the Gobi.[1] The holotype, IVPP V9492, was found in a layer of the Shishugou Formation dating from the Oxfordian, about 160 million years old. It consists of a partial skeleton lacking the skull. The postcranial skeleton is rather complete, missing only the front part of the neck, the left shoulder girdle, the left forelimb and the feet.[1] The quality of the bones was poor and deteriorated during preparation. DescriptionKlamelisaurus was a medium-sized sauropod. In 2010, Gregory S. Paul estimated its length at fifteen metres, its weight at five tonnes, at the same time presuming it represented the adult form of Bellusaurus.[2] In their osteological description of Bellusaurus, Moore et al. (2018) refuted the possible synonymy of Klamelisaurus and Bellusaurus by pointing to the slightly older age of the former and non-ontogenetic differences between the two genera.[3]Zhao in 1993 established a single explicit autapomorphy: the upper end of the ulna is expanded.[1] In 1993 Zhao erected a new subfamily, Klamelisaurinae, of which Klamelisaurus was the only member. He assigned Klamelisaurinae to the obscure sauropod clade Bothrosauropodea.[1] It was considered of uncertain classification by Upchurch et al. (2004), possibly being a non-neosauropod eusauropod.[4] References1. ^1 2 3 {{cite journal|title=A new Mid-Jurassic sauropod (Klamelisaurus gobiensis gen. et sp. nov.) from Xinjiang, China|author=Zhao Xijing|year=1993|journal=Vertebrata PalAsiatica|volume=31|number=2|pages=132–138|url= http://www.paleoglot.org/files/Zhao_93.pdf}} 2. ^Paul, G.S., 2010, The Princeton Field Guide to Dinosaurs, Princeton University Press p. 178 3. ^Moore AJ, Mo J, Clark JM, Xu X.
