Argentinosaurus, means 'Argentine lizard'.It was discovered by Bonaparte and Coria in 1993. The remains found in South America. It has a dimensions of 40 meters length and 1oo tonnes weight.
There are classification of Argentinosaurus they are Saurischia, Saurodopa, and Titanosauridae.
Argentinosaurs, belongs to the family of land-dwelling animals which were probably the longest and heaviest which have ever existed. It was a gigantic dinosaur with an extremely long neck and tail, a some what slender body and tiny head; so, to excavate a complete skeleton of such a large dinosaur is very rare.
For Argentinosaurus, for example, we have found only some sections-some vertebrae, fragments of ribs, one tibia and pelvic bones. The experience of the palaeontologists, their expert knowledge of anatomy of the giant plant-eating sauropods and the ratio of measurements between each section has enabled them to reconstruct their size and appearance.
Argentinosaurus, is a record-breaking animal. Its 100 tonne weight makes it the heaviest dinosaur known so far.
Now, as then the sauropod dinosaurs had huge pillar-like legs in order to support their enormous weight. The digits rested on flexible, soft pads like those of the elephant, the largest land-dwelling animal today.
