In 2009, I posted that paleontologists found the fossilized remains of the world's largest snake, a 42-foot-long relative of the boa constrictor. Paleontologists from the University of Toronto dubbed the species Titanoboa cerrejonensis for the Cerrejón region of northern Colombia where they found the remains. The snake snacked on crocodiles. As part of a new Smithsonian documentary "Titanoboa: Monster Snake," sculptor Kevin Hockley built a life-size replica of the beast.
