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".
Buitreraptor
"Buitreraptor" is from the early Late Cretaceous Candeleros Formation, dating to the Cenomanian-Turonian, about 94 million years ago, when South America was an isolated continent like Australia today. It was uncovered in a famous fossil site named "La Buitrera", the "vulture roost". Although dinosaurs are rare in this site, another nearby site had earlier yielded "Giganotosaurus", one of the largest known carnivorous dinosaurs.
