This Is The Biggest Skeleton I've Ever Seen

Weighing in at over 70 tons, and 122 feet long, the Titanosaur was one of the largest dinosaurs to ever roam the Earth. Now the skeleton of one is on display at the American Museum of Natural History. Just look how tiny those people look next to it!

Measuring 122 feet, the Museum's new exhibit, The Titanosaur, is big--so big that its head extends outside of the Museum's fourth-floor gallery where it is now on permanent display.

This species of dinosaur, a giant herbivore that belongs to a group known as titanosaurs, is so new that it has not yet been formally named by the paleontologists who discovered it. The Titanosaur lived in the forests of today’s Patagonia about 100 to 95 million years ago, during the Late Cretaceous period, and weighed 70 tons. It is one of the largest dinosaurs ever discovered.

The fossils on which this cast is based were excavated in the Patagonian desert region of Argentina by a team from the Museo Paleontologico Egidio Feruglio led by José Luis Carballido and Diego Pol, who received his Ph.D. at the American Museum of Natural History.

In this video, Dr. Mark Norell, chair and Macaulay Curator in the Division of Paleontology, describes how such a massive animal could have supported its own weight and why the Titanosaur is one of the more spectacular finds during what he describes as "the golden age of paleontology."
