. The authors conclude from examining the skeleton that "The record of ''Zapalasaurus bonapartei'' shows that, at least in the

, basal diplodocoids were more diverse than previously thought." ''Zapalasaurus'' is assumed to have a long neck which would have been developed for feeding adaption, allowing its neck to swing in an arc like shape. This would allow ''Zapalasaurus'' to browse a wide variety of plants and greens without having to walk very far.
