The exact size of Argentinosaurus is hard to estimate due to the incompleteness of its fossilised remains. But it is one of the largest land animals ever found. It carried on growing throughout most of its lifetime. Other similarly massive dinosaurs include Patagotitan and Puertasaurus. They were all titanosaurs, a type of sauropod.
Argentinosaurus probably used its long neck to sweep the ground or to reach high up in search of vegetation. The hatchlings of Argentinosaurus would have taken 15 years to grow to adulthood and in that time they would have been very vulnerable to predators, such as Giganotosaurus.
