Argentinosaurus may have been the biggest dinosaur ever. Like some of the other really huge dinosaurs, such as Supersaurus, 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 that would require massive amounts of food each day. But it was not always like that. They would start out small and would be easy prey. They would be abandoned since the evolutionary tactic would be to have so many chicks that predators could not eat them all.

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.[1]
