New York is home to big buildings, big stars and now, thanks to a new exhibit at the city’s natural history museum, big dinosaurs.

The biggest of the big, in fact.

“The World’s Largest Dinosaurs” features many life-size models of the enormous animals that lived for 140 million years and grew to be longer than 150 feet, the length of four city buses.

The biggest star of the exhibit is a detailed model of a 60-foot-long Mamenchisaurus (pronounced mah-MUN-key-sore-us). “It’s a very long-necked animal from China,” said Mark Norell of the museum’s paleontology department. Its neck was 30 feet long!

The exhibit looks at how these enormous creatures managed to eat enough to keep themselves alive and moving.

“We have a 5-foot-by-5-foot-by-5-foot cube that represents the amount of vegetation that one of these animals would’ve had to eat in a single day,” Norell said.

If you’re visiting New York, be sure to check out the exhibit — and everything else that’s really cool — at the American Museum of Natural History. The exhibit will be up through Jan. 2. If you’re not, look at the pictures on this page and be amazed.
