Argentinosaurus huinculensis had been estimated to be about 32.2-37 meters long and 73.3-90 tonnes in weight when fully grown. Like all sauropods, it probably ate the leaves off the tops of conifers. It was a titanosaur, some of the biggest animals to have ever walked on land, and grew to that size to protect itself from predators like Mapusaurus except that it could nearly outrun any predator away. It also most likely traveled in herds from place to place, finding where the vegetation was more dense, the best possible food areas are after they've stripped the last area down. It was also one of the last giant sauropods to have lived, and may have shared its environment with another, smaller sauropod called Amargasaurus. Argentinosaurus is considered to be the largest dinosaur to scientists but actually there are about 3 more sauropods which compete with size with it, an Unnamed Patagonian titanosaur at 40 meters, Alamosaurus at 30-37 meters, Puertasaurus at 30-37 meters, Bruhathkayosaurus at 44 meters and Amphicoelias at 58 meters, people think that that's because of scientists have less evidence that they actually existed or not, making it a controversial and theoretical debate.

Description

Argentinosaurus was an extremely large dinosaur, probably the largest in its area. Its long neck gave it a better approach than the other herbivorous dinosaurs in its areas, because it was able to feed from more various places, enhancing its feeding capabilties. Like other herbivorous dinosaurs, Argentinosaurus probably swallowed stones, better known as Gastroliths, to help grind its food, to easily turn its food into nutrition, for its massive growing rate. Argentinosaurus probably used its size as primary defense against giant predators like Mapusaurus, or Giganotosaurus, and its also reckoned that the Argentinosaurus could rear up on its hind legs to make itself look bigger. Many sources document that the Argentinosaurus bred, a lot. To ensure the survival of its species, and with direct fossil evidence from Patagonia (massive breeding site), it would've have frequent nesting times.
