Passersby at Grand Central Station in New York City will have a new phenomenon to ogle at during their morning commutes on Thursday: a display of the world's largest snake to ever live, the titanoboa, measuring at 48-feet-long.

Don't worry though, it's only a replica. A really large replica, about the same size as a school bus in length.

According to Yahoo News, those at Grand Central can feast their eyes upon a full-scale replica of the titanoboa (titanoboa cerrejonensis) beginning on Thursday, March 22 before the 48-foot-long, 2,500-pound titanoboa snake is moved over to the Smithsonian Institute's National Museum of Natural History in D.C.

The snake will make its first appearance in New York beginning on Thursday to promote the exhibit in Washington D.C. which opens on March 30 and will make its way around museums in the country beginning Fall 2013.

Smithsonian spokesperson Randall Kremer hopes the replica will scare the daylights out of people in an effort to communicate science to a lot of people.

For many years, scientists believes the reticulated python, which measured up to 20 feet, was the largest snake known to man.

However, in 2009, scientists debunked the largest snake debacle and found the titanoboa measured over twice as long, according to Time magazine, before it died 60 million years ago along with the dinosaurs.

The model is made out of  fossilized bone of a real titanoboa found in a Colombian coal mine in 2002. 

The exhibit will open at the Smithsonian Institute's National Museum of Natural History in D.C. on March 30, in addition to a television show on the Smithsonian Channel, Titanoboa: Monster Snake, on April 1.
