Food: Titanoboa was one of the largest land animals of it's time, so it needed a lot of food to keep healthy. However it did not eat that often. The crocodiles of the ancient Cerrejon rainforest fell prey to Titanoboa, after eating it, the snake would not have to feed for a whole year. Titanoboa was an ancestor of Boas and Anacondas, and like them it was a constrictor, but could give ten times the pressure of that from a common anaconda. Titanoboa would also eat large fish on usual occasion. Like modern-day snakes, it could also dislocate its jaws to help swallow prey bigger than its own head whole.
