摘要
New pareiasaur specimens from the Sunjiagou Formation of Xuecun, Liulin, Shanxi, China are described. These new specimens comprise two marginal teeth from the upper jaw (IVPP V 18613) and an incomplete left dentary with teeth (IVPP V 18614). They provide novel anatomical information and allow the direct comparison of Sanchuansaurus pygmaeus with Huanghesaurus liulinensis. The two taxa cannot be differentiated by the known features, and both taxa are declared junior synonyms of Shansisaurus xuecunensis.
