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".

He is best known for having directed the field study and co-naming of "Argentinosaurus" (possibly the world's largest land animal ever) in 1993, and "Giganotosaurus" (one of the largest known terrestrial carnivores), in 1996 among other landmark South American dinosaurs. He is a member of the Argentine Paleontological Association, Society of Vertebrate Paleontology, Paleontological Society and The Explorers Club.
