At 122 feet, meet the world's biggest dinosaur!

There's a new top dinosaur in town: The 122-foot-long Titanosaur.

If you thought the dinosaurs in “Jurassic Park” were big, wait until you see the newly discovered 122-foot-long dinosaur that is displayed at the American Museum of Natural History.

And if you can’t think how big that is, picture this: it is so big, it’s head grazes the ceiling and pokes out through it’s exhibition hall.

Known as the Titanosaur, it is one of the largest dinosaurs ever discovered, and lived 100 million years ago.

Researchers dug up the bones in a desert region of Argentine Patagonia, after a farmer found what he suspected to be fossils.

The Titanosaur is believed to have weighed, when walking the Earth roughly 100 million years ago, some 70 tonnes -- as heavy as at least 10 African elephants. Its thigh bone is nearly 8 feet long.

“Everything was extremely large,” said Diego Pol, one of the palaeontologists who excavated the previously unknown dinosaur in Argentina in 2014. “After a few days working, we realised it was huge.”

According to the palaeontologists, despite their intimidating stature, researchers think that these giant dinosaurs were herbivores, eating only plants.

The Titanosaur’s initial discovery began with a call from a farmer who thought he had found fossils in a remote desert region of Argentine Patagonia, in the southernmost reaches of South America. A quick survey by Pol and colleagues from the Museo Paleontológico Egidio Feruglio in the city of Trelew suggested it might be a significant find.
