Bashunosaurus is a genus of potentially

Kaijiang, China
. The type and only species is Bashunosaurus kaijiangensis.

Discovery

The

dorsal vertebrae, a partial left scapula, and a right humerus, ulna, ilium, femur, tibia, and fibula. An additional right ilium, specimen KM 20103, was assigned as a paratype.[2]

History

The name "Bashunosaurus kaijiangensis" first appeared in Ouyang's description of Abrosaurus in 1989,[3] although without a description or diagnosis, making it a nomen nudum (i.e. a nickname that is unavailable for use as an actual scientific name). Li et al. (1999), however, attribute the naming to "Kuang, 1996", still considering it a nomen nudum.[4] Although it was finally formally named by Kuang in 2004,[2] George Olshevsky's influential online Dinosaur Genera List continued to list it as a nomen nudum and possible synonym of Datousaurus.[5] It was largely ignored in modern literature until Dai et al.'s description of Yuzhoulong in 2022, where it is discussed.[6]

Description

As a sauropod, Bashunosaurus would have been a large quadrupedal herbivore with a robust body. Kuang (2004) estimated its length as about 10–12 m (32.8–39.4 ft).[2]

Classification

The precise classification of Bashunosaurus is unknown, with different authors proposing different ideas. Li et al. (1999) consider it a

neosauropod similar to Bellusaurus, Daanosaurus, Dashanpusaurus and Klamelisaurus, although they comment that it is also "similar to Abrosaurus and Datousaurus".[7] Dai et al. (2022) compare the taxon to Yuzhoulong, noting the fact it was described as a macronarian, although they caution that a reappraisal is needed to confirm this in a cladistic context.[6][8]
