       Guaibasaurus is known from fairly good remains,‭ ‬though the skull is unknown.‭ ‬When first described,‭ ‬Guaibasaurus was considered to be a potential theropod dinosaur,‭ ‬though later a similarity with the primitive sauropodomorph dinosaur Saturnalia was noted,‭ ‬and now Guaibasaurus is usually seen as a very primitive sauropodomorph dinosaur.
