The fossilized remains of gigantic crocodiles have been discovered in the Aguja Formation in the south-central part of the Big Bend National Park. These are among the largest crocodiles ever known.
With lengths of 40–50 feet and jaws studded with 6-inch teeth, these powerful predators were extraordinarily equipped to feed upon a variety of dinosaurs. In fact, dinosaur bones have been found here that are heavily damaged and covered with distinctive crocodile bite marks!
