Quick Summary

Argentinosaurus was a genus of sauropod dinosaurs that lived during the Cretaceous period. Discovered in Argentina, it is considered one of the largest dinosaurs ever found, with estimates suggesting a length of 37 to 40 meters (121 to 131 feet) and a weight of up to 100 metric tons. This massive, long-necked, herbivorous dinosaur may have outweighed other giants by 40 metric tons. The only known fossil specimen for this genus was found in Argentine Patagonia.12
