The genus and species were first named in 2000 on the basis of an incomplete adult skeleton. More complete skeletons were described in 2011, and a complete skeleton belonging to a juvenile was described in 2013. In 2011 Guanlingsaurus liangae was reassigned to the genus Shastasaurus, which includes two species from North America that are known from more complete fossils than Guanlingsaurus. However, the description of the juvenile specimen in 2013 revealed several features that make G. liangae distinct from Shastasaurus species, and the name was reinstated.
