       Yimenosaurus is one of the more popular sauropodomorph dinosaurs thanks to the large number of fossils from several individuals that make up the genus.‭ ‬At the time of writing the only uncertainty concerning Yimenosaurus are the limbs,‭ ‬which have a distinct lack of representation.‭ ‬Yimenosaurus is also known to have easily attained sizes of up to nine meters‭ ‬long,‭ ‬with some estimates hinting at a slightly‭ ‬larger size than this,‭ ‬which easily make Yimenosaurus one‭ ‬of the largest sauropodomorph dinosaurs that we have discovered thus far.
       Yimenosaurus lived in China at the beginning of the Jurassic period,‭ ‬and already the future quadrupedal body form of the later sauropod dinosaurs which will be descended from sauropodomorphs is already apparent.
