Sarcosuchus

Sarcosuchus had a substantial overbite, and its jaws are studded with more than 100 teeth, including a row of enlarged, bone-crushing incisors that enabled the reptile, said Prof Sereno, "to eat far meatier prey than fish".Sarcosuchus  meaning "flesh crocodile") is an extinct genus of crocodyliform and distant relative of the Gavialidae that lived 112 to 94 million years ago. It dates from the early Cretaceous Period of what is now Africa and South America and is the largest crocodilymorph that ever lived.
