The Cerrejón crocodile the scientists unearthed came out to be about 28 feet, which is bigger than any crocodile that we have alive today. More importantly, it was of a size to match the croc from the dinosaur era, Sarcosuchus. Now that we know how large the croc was, Dr. Greg Erickson can finally estimate the power of its monstrous bite. It is of a magnitude equal to that of a T. rex.
