آرجنتینوسوروس was a massive dinosaur that lived during the Late Cretaceous period, around 94 to 97 million years ago. It belonged to the group of long-necked dinosaurs known as sauropods. This dinosaur was one of the largest land animals ever, reaching lengths of up to 100 feet (30 meters) and weighing around 100 tons. Fossils of آرجنتینوسوروس were discovered in Argentina, which is how it got its name. Its long neck allowed it to reach high vegetation, while its large body provided protection from predators. This dinosaur is an important part of our understanding of prehistoric life and the diversity of dinosaurs.
