Deinosuchus lived during the Late Cretaceous, ~82 - 73Myrs ago. The first remains were discovered in North Carolina in the 1850s, and the genus was first described in 1909. --WP

Although Deinosuchus was far larger than any modern crocodile or alligator, with the largest surpassing 9m (30 ft) in length, its overall appearance was fairly similar to its smaller relatives, but with a proportionally longer skull than modern crocodilians. It had large, robust teeth built for crushing, and its back was covered with thick hemispherical osteoderms (bony scales). One study indicated Deinosuchus may have lived for up to 50 years, growing at a rate similar to that of modern crocodilians, but maintaining this growth over a much longer time.
