Meet the Titanosaur

Measuring 122 feet in length, The Titanosaur is so big that its head extends outside of its new home in the Museum's fourth-floor gallery.

The Titanosaur lived in the forests of today’s Patagonia about 100 to 95 million years ago, during the Late Cretaceous period, and is one of the largest dinosaurs ever discovered. 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 this animal is one of the more spectacular recent finds in paleontology.
