Zapalasaurus is a genus of sauropod dinosaur described by Leonardo Salgado, Ismar de Souza Carvalho and Alberto Garrido in 2006.

[3] It was named after the city of Zapala, which is approximately 80 kilometres (50 mi) away from where the holotype was discovered.

It was a diplodocoid, a long-necked herbivore, and it lived during the Early Cretaceous.

The authors conclude from examining the skeleton that "The record of Zapalasaurus bonapartei shows that, at least in the Neuquén Basin, basal diplodocoids were more diverse than previously thought."

This would allow Zapalasaurus to browse a wide variety of plants and greens without having to walk very far.
