Saltasaurus was a large plant-eating dinosaur with an elongated neck and bony armored plates on its body. It was a titanosaurid sauropod that lived during the late Cretaceous Period, about 83 to 79 million years ago. Fossils have been found in Argentina.
Saltasaurus was named by paleontologists J. Bonaparte and J. Powell in 1980. Salta is the name of the Northwestern Argentinian Province where fossils were found. They include: a few oval and circular armored plates, hundreds of bumps which covered its back (roughly 1/4 inch = 6-7 mm in diameter), and several incomplete skeletons, including some vertebrae, limb bones, and jaws.
A large titanosaurid nest was found in Auca Mahuevo, in Patagonia, Argentina. The small eggs had fossilised embryos, complete with skin impressions.
