WATCH: Natural History Museum's Titanosaur Gets Cleaning

UPPER WEST SIDE, NY — Thousands of people walk the halls of the American Museum of Natural History every day to take in one of the world's most impressive collections of dinosaur fossils and models, and it takes a lot of hard work to make sure the displays look presentable.

The museum peeled back the curtain Wednesday on its maintenance efforts and live streamed the cleaning of one of its largest and most popular models, the Titanosaur skeleton. A museum staffer took a vacuum cleaner to the massive 122-foot-long model — based on scans of a real fossil discovered in Argentina — with extreme care while being hoisted up to the skeleton on a lift.

It was actually pretty mesmerizing to watch, and more than 10,000 viewers tuned into the Facebook live stream. Despite the fossil's enormous size, it only took museum staff about 30 minutes to clean the gigantic skeleton.

The Titanosaur model has been on display at the American Museum of Natural History since 2016. The fossil it was based off was discovered in the Patagonia region of Argentina, which resulted in a scientific named of Patagotitan mayorum. Scientists estimate the species was a giant herbivore that weighed about 70 tons and roamed the Patagonia forests about 100 millions years ago.
