110 million years ago, a lush river flowed through the heart of what is now a desert in Africa. Lurking in the depths of the river, a humungous monster waited for its prey to come to the river’s edge to drink...and to die. More than 40 feet long, this giant ancestor of the crocodile stalked and killed dinosaurs. In 1997, dinosaur hunter Paul Sereno discovered the enormous reptile fossil named SuperCroc.
