Saltasaurus

Saltasaurus (which means "lizard from Salta") is a genus of saltasauriddinosaur of the Late Cretaceousperiod of Argentina. Small among sauropods, though still heavy by the standards of modern creatures, Saltasaurus was characterized by a short neck and stubby limbs. It was the first genus of sauropod known to possess armour of bony plates embedded in its skin. Such small bony plates, called osteoderms, have since been found on other titanosaurians.
