Argentinosaurus may have been the biggest dinosaur ever. Like some of the other really huge dinosaurs, such as Ultrasauros , very little of Argentinosaurus has been found, so it is hard to tell exactly what it may have looked like. The only thing that is certain is that it was a huge, long-necked plant eater.
Argentinosaurus was discovered by a retired oil worker and was formally described in 1993. The few bones include hipbones, backbones, and a tibia (lower leg bone). One vertebra was over four feet (1.3 m) tall and the tibia was 58 inches (155 cm) long. A number of prominent scientists have stated that this member of the South American titanosaur family was the largest dinosaur that ever lived.
