We here describe the complete skeletal anatomy of Anshunsaurus huangguoshuensis that previously remained unknown. The description includes a review of the dorsal side of the skull as well as the first description of the ventral side of the skull and of the postcranial skeleton. A new phylogenetic analysis supports the monophyly of Askeptosauridea and Thalattosauridea; Endennasaurus is found to be closely related to Askeptosauridae.
