Saltasaurus

Saltasaurus was a genus of titanosaur, a diverse group of herbivorous sauropod dinosaurs that lived from the Late Jurassic to the end of the Cretaceous Period. These dinosaurs were characterized by their long tails, long necks, and small heads, with stockier bodies and wider stances than other sauropods.1

Saltasaurus is notable for its relatively small size compared to other titanosaurs, measuring approximately 12.2 to 12.8 meters (40 to 42 feet) in length and weighing under 7 metric tons (7.7 tons). Unlike some of its larger relatives that relied on sheer size for defense, Saltasaurus possessed osteoderms, or bony armored plates, covering its body, which likely provided protection against predators. Fossils of Saltasaurus have been discovered in northern Argentina.21
