In Depth
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.
