Mendozasaurus facts are all about the herbivore dinosaur of the Late Cretaceous period.

Mendozasaurus was a herbivore dinosaur of the Upper Cretaceous period. Not much information is available on this species as only a single fossil specimen was retrieved from the Mendoza Province of Argentina. This included only partial postcranial remains that were studied and described by paleontologist González Riga.

These dinosaur species were grouped under the Sauropoda clade. They had huge bodies with long necks and were herbivores in nature.
