Dinosaur size
There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur "Argentinosaurus huinculensis", which is the largest dinosaur known from uncontroversial evidence, estimated to have been and long. Some of the longest sauropods were those with exceptionally long, whip-like tails, such as the "Diplodocus hallorum" (formerly "Seismosaurus") and the 33- to 35-metre-long (108–115 ft) "Supersaurus". The tallest was the "Brachiosaurus".
Plaza Huincul
The Argentinosaurus is the largest dinosaur to walk on earth and it was discovered in Plaza Huincul by Guillermo Heredia. It is estimated that it lived on Earth 94-97 million years ago. The Argentinosaurus has a height of 35 meters and Paleontologists have estimated that it may have weighed as much as 75 to 100 tonnes. The Argentinosaurus was discovered in 1987 by a rancher who mistook the legbone of a dinosaurs for petrified wood
