A replica of a Titanosaurus Australis Dinosaur skeleton is displayed in the "Dinosaurs of the Patagonia" exhibition at a mall of Medellin, Colombia on February 19, 2009. The recent dinosaur find in Argentina is thought to be even bigger and belongs to the same family of Titanosaurus dinosaurs.
Dinosaur remains thought to belong to the largest specimens ever found were unveiled by paleontologists in Argentina.
The dinosaurs were found by a farmworker in the Patagonia region of Argentina and are part of a group of dinosaurs known as Titanosaurus, an herbivorous sauropod with a long neck and tail. Scientists based their guess on the dinosaur's size by extrapolating from the enormous femur bone.
However, full skeletal remains have not been uncovered yet and there have been many cases of dinosaurs' sizes being overestimated upon initial discovery, said Brian Switek, who writes about dinosaurs for National Geographic.
