Argentinosaurus

He was the largest dinosaur, as well as the largest land animal, ever known

Argentinosaurus has been known to science since 1993. Evidence of it was originally discovered in 1987, when a fossil the size of a fully grown human being was unearthed on a ranch in Argentina. The rancher thought the fossil specimen was a large chunk of petrified wood, and it wasn’t until 1993 that it was reclassified as a single vertebra belonging to a new species of sauropod. Although no complete skeletons of Argentinosaurus have been found, estimates of the dinosaur’s length (based on projections of the size of the rest of the body using existing fossils) range from 37 to 40 meters (about 121 to 131 feet), and it was thought to have weighed 90 to 100 metric tons (99 to 110 tons). By these measures, Argentinosaurus was the largest dinosaur, as well as the largest land animal, ever known.
