Sauroposeidon
The press release in 1999 immediately garnered international media attention, which led to many (inaccurate) news reports of "the largest dinosaur ever!". While "Sauroposeidon" likely represents the tallest known dinosaur taxon, it does not hold records for either the longest or most massive. "Patagotitan" or "Argentinosaurus" make better candidates for the title "World's Largest Dinosaur" (presuming to ignore, as is conventional, "Amphicoelias"), though incomplete fossil evidence makes exact rankings impossible.

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.
