American Museum of Natural History debuts Titanosaur, largest known dinosaur

It was an unveiling of epic proportions.

After an 18-month excavation, millions of years of fossilization and a spirited New Year’s-esque countdown from 10, the American Museum of Natural History pulled back the velvet curtain and debuted their newest exhibit: The Titanosaur.

This 122-foot-long dinosaur — so new that the scientists who discovered it in Argentina in 2014 didn’t even have a name for it — peeks out of the gallery and welcomes visitors in to another signature piece of AMNH.

Like standing under the great blue whale (which at 94 feet is actually 30 feet shorter than the Titanosaur), walking past this enormous Titanosaur is awe-inducing.

Ellen V. Futter, president of AMNH, remarked that she wanted the Titanosaur to offer a “hospitable welcome” to museum guests.

A natural herbivore, the nonpredatory Titanosaur is indeed a remarkable inclusion in the AMNH paleontology collection.

The Titanosaur opens to the public on Friday. Here’s what you need to know about the magnificent dino.
