Watch: Giant Barosaurus Fossil At Natural History Museum Gets Cleaning

UPPER WEST SIDE, NY — Last week it was the mammoth's turn, this week it's on to the Barosaurus. It's spring cleaning season at the American Musuem of Natural History, and the museum is letting people in on the action.

The museum is sharing videos of some of its largest fossils getting cleaned. The natural history museum's Barosaurus, located in Theodore Roosevelt Rotunda, is one of two specimens displayed in the entire world. The Barosaurus was a huge animal, so its fossil certainly collects a lot of dust every year.

Despite the fossil's enormous size, it only took museum staff about 25 minutes to clean the gigantic skeleton. The cleaners used some sort of high-pressure vacuum and a long, multi-colored, fluffy duster to give the bones a nice shine.

As of this writing, more than 20,000 people viewed the Barosaurus' annual cleaning.

"I love these cleaning segments!! Makes my efforts at home seem so much more manageable," Facebook commenter Michele Kepinski said.

Check out a video of the cleaning below:

Here's something you may not have known about the American Museum of Natural History's Barosaurus: It's actually made of a cast of real Barosaurus bones. The fossil is displayed in a reared position to simulate a Barosaurus protecting it's young. The real bones wouldn't be able to support this sort of display, according to the museum's website.
