Fossil representation: Initially described from fragmentary post cranial remains,‭ ‬further fossils have now been attributed to it.

       Dashanpusaurus is identified as a macronarian sauropod that might by related to the North American Camarasaurus,‭ ‬which means that it may have been a more specialised high browser.‭ ‬This fits in with another genus of sauropod from the Lower Shaximiao Formation called Abrosaurus that has also been considered to be a possible relative of Camarasaurus.‭ ‬Interestingly other sauropods from the Lower Shaximiao include Omeisaurus and Shunosaurus but these are very different to both Abrosaurus and Dashanpusaurus in form.‭ ‬While the presence of these dinosaurs in the same fossil formation proves that they were active in the‭ ‬same approximate location and time as one another,‭ ‬they likely adopted different feeding strategies and thus avoided something with each other.
       Other dinosaurs of the Lower Shaximiao include the small ornithischian Agilisaurus and the stegosaur Huayangosaurus,‭ ‬as well as numerous predatory dinosaurs such as Gasosaurus,‭ ‬Leshansaurus and Kaijiangosaurus.‭ ‬However there was one theropod in particular called Yangchuanosaurus that would have been a particular threat to sauropods like Dashanpusaurus.‭ ‬Yangchuanosaurus was described from a set of remains indicating that it was an eight metre long predator,‭ ‬but further isolated fossils have since revealed that an upper length of eleven meters was possible.‭
