Argentinosaurus belongs to the Titanosaur class of sauropod dinosaurs, and its name is very simple, meaning a dinosaur discovered in Argentina. Survival period: 100 million years ago, mid Cretaceous Albian stage -93 million years ago, late Cretaceous Senonian stage. It is one of the largest land dinosaurs discovered. It is one of the largest animals that once roamed the earth, with a height of 12 meters and a length of 42 meters. Among all modern organisms, only the fragile double chambered dinosaur is longer than it. There are some other dinosaurs that are as long as the Argentinosaurus, and some that are taller than it. However, Argentinosaurus is still much heavier than other dinosaurs, possibly weighing up to 94 tons.
