Argentinosaurus was one of the largest land animals ever, growing up to 35 meters (115 feet) long and weighing around 100 tons. It lived 95 million years ago during the Late Cretaceous in what is now Argentina. This giant sauropod had thick, pillar-like legs to support its massive body and likely moved in herds for protection. It was a herbivore, using its long neck to reach high vegetation. Despite its size, it was probably slow-moving to conserve energy. Fossil remains of Argentinosaurus are s

Sauropods were the largest land animals to ever walk the Earth, known for their long necks, massive bodies, and tiny heads. They lived from the Late Triassic to the end of the Cretaceous (about 210–66 million years ago) and included famous species like Brachiosaurus, Diplodocus, and Argentinosaurus. These plant-eaters could reach lengths of over 30 meters (98 feet) and weigh more than 70 tons. Their long necks helped them feed on high vegetation, and their pillar-like legs supported their enormo
