This great size ensured that mature Argentinosaurs have no predators, except for such dinosaurs as giganotosaurus and the giant prehistoric crocodilian sarcosuchus. One of the biggest members of this great family (though some, like Seismosaurus, were even larger), Argentinosaurus grew up to 35 metres(115 ft) in length, making it bigger than even its relatives, such as Alamosaurus and Saltasaurus. Argentinosaurus was a titanosaur dinosaur, the last group of the sauropod dinosaurs that were also the most physically imposing.
