History and Discovery

It was in 1987 that the remains of the animal were excavated for the very first time by an Argentinian rancher. Interestingly, the huge foot of the Argentinosaurus huinculensis was mistaken for a large piece of log wood, and the big size vertebra, about the size of a human was also dug out, along with.

Argentinosaurus Skeleton

This specimen was unearthed from a fossil discovery site located in Argentina’s Neuquén Province Huincul Formation of the Río Limay Subgroup in, Argentina. However, the fossil was published and described in 1993 by two paleontologists from Argentina, Rodolfo Coria and José F. Bonaparte. The Huincul Formation was a member of the Río Limay Formation.

Both these scientists also specified the timeframe of the discovered animal that lived during the late Cenomanian faunal stage of the Cretaceous period, approximately 96 to 94 million years back.

Physical Description

Argentinosaurus Skull

Very little is known about this giant dinosaur Argentinosaurus since information that could be gathered from bits and pieces from their skeleton-fossil was not enough to have a complete inference.

Argentinosaurus Dinosaur

Scientists think that the Argentinosaurus may be the largest of the dinosaurs, being a member of the group of the largest dinos ‘titanosaur’. The Argentinosaurus had a very long neck, almost an equally long tail, but with a relatively small skull-size (head) when fully grown.

Behavior

Argentinosaurus Size

Argentinosauruses were not solitary creatures, but would move in herds of around 20 individuals, foraging for food in densely vegetated regions to feed. When the food resources are exhausted, they would move on to a different place to find a new region to graze.

It’s evident that most of the contemporary species didn’t dare attack this gigantic animal except for the huge and massive Giganotosaurus.

Diet

The Argentinosaurus were herbivorous (plant-eating) animals, feeding on leaves, seed and fruit especially from the high branches of the conifers.
