The American Museum of Natural History Debuts a New Dinosaur, the Titanosaur

Move over, Apatosaurus, there’s a new dinosaur in town.

The American Museum of Natural History unveiled a replica of the largest dinosaur discovered to date—the Titanosaur. 

Found in Argentine Patagonia in 2014, this dinosaur is 122 feet long and would have weighed about 70 tons. The Apatosaurus, the museum’s former largest dinosaur, was 86-feet long and would have weighed around 30-40 tons. The Titanosaur and Apatosaurus are members of the sauropod family, which are herbivores distinguished by their very long necks, small heads, long tails, and four, thick legs.

The Titanosaur is so large that it cannot fit in either of the museum’s two dinosaur exhibitions on the fourth floor (Hall of Ornithischian Dinosaurs and Saurischian Dinosaurs), so it is in its own gallery and part of its 39-foot-long neck extends out of the exhibit.
