A prehistoric monster snake has made its way to the Smithsonian Institution in Washington, D.C. The National Museum of Natural History opened an exhibit featuring a life-size replica of Titanoboa on Friday. The fossil was found several years ago in a coal mine in Colombia. When it was alive, the snake weighed 2,500 pounds and was 48 feet long. It was found near fossilized plants and creatures dating to more than 60 million years ago. The exhibit will be on view through Jan. 6.
