       Named after the Andes Mountains,‭ ‬Andesaurus was a titanosaurian sauropod dinosaur from South America,‭ ‬but one known from only incomplete remains.‭ ‬This makes it hard to be certain about such things as a total size or even a preferred diet beyond just general plants.‭ ‬The vertebrae of Andesaurus though suggest that the genus was a basal‭ (‬primitive‭) ‬titanosaur.
       Hailing from the Candeleros Formation,‭ ‬Andesaurus may have lived alongside the rebbachisaurid sauropods Limaysaurus and Nopcsaspondylus.‭ ‬Other dinosaurs active here include dromaeosaurids like Buiteraptor and alvaersaurids like Alnashetri.‭ ‬The dinosaurs of most concern to Andesaurus however would have been large abelisaurs like Ekrixinatosaurus,‭ ‬to even bigger carcharodontosaurids like Giganotosaurus,‭ ‬either one of these were capable of taking down a moderately sized sauropod.
