Deinosuchus (meaning "terrible crocodile") is an extinct genus of alligatorid from the Upper Cretaceous (Campanian) of North America. It was thought for several decades to be the largest crocodilian that ever lived. Deinosuchus is known mainly from skull material, and recent studies have reduced its estimated length. Some other giant crocodilians, including Sarcosuchus (the "SuperCroc"), Purussaurus and Rhamphosuchus, were as big or bigger, but accurate comparisons are difficult as Sarcosuchus is the only species known from a largely-complete skeleton. |
