Borealosuchus was a survivor of the catastrophic mass extinction at the end of the Cretaceous Period. A prehistoric crocodilian (or a close relative of the crocodilians), it lived twenty million years during the Age of Dinosaurs and lived another twenty million years during the Age of Mammals. Although Borealosuchus started out small, it become a top predator in the new Cenozoic world. It is also one of the most important prehistoric reptiles in understanding the early evolution of Crocodilia, and may be close to what the last common ancestor the of today's crocodilians looked like.
