The specimen, which has historical significance, has been erratically attributed to either a sauropod or a theropod on the basis of vague phenetic resemblances. Some of the key character state transformations, relevant to the evolution of the sauropod skull, are listed. This taxon demonstrates that basal sauropods possessed a fleshy cheek associated with a buccal emargination and a lateral ridge on the dentary. Nevertheless, the best available evidence indicates that this taxon is probably a very basal sauropod. Nevertheless, incorporation of all of this material into phylogenetic analyses will probably yield new insights into the early evolution of sauropod crania and feeding mechanisms. This raises the question of why herbivorous sauropods, having inherited a fleshy cheek, should need to lose it later in their evolutionary history. The earliest known sauropod dinosaur and the first steps towards sauropod locomotion. Chinshakiangosaurus represents one of the earliest and most basal sauropods in which cranial material is preserved. For instance, why is there such a lack of large terrestrial animals, especially sauropod dinosaurs? Anchisaurus may provide an important glimpse into the feeding strategies of the most basal sauropods. The relevant surfaces are eroded so it cannot be determined if the attachment of the orbitosphenoid was loose, as in prosauropods, or firm or fused, as in theropods and sauropods. The evolution of sauropod feeding mechanisms. The earliest known sauropod dinosaur. Fossil sauropod tracks have been reported from the formation.

The arrangement of the forefoot bone ("metacarpal") columns in eusauropods was semi-circular, so sauropod forefoot prints are horseshoe-shaped.
