Sarcosuchus was the largest crocodilian that ever lived. This giant could grow to a length of 40 feet long. This Mega Crocodile was something like a Gharial on steriods. But Sarcosuchus was not just eating fish. While the skull of Sarcosuchus is narrower than the skull of Deinosuchus, and trust me, I've seen the 2 animal's skulls mounted close to each other, the skull is not too skinny. Plus, unlike the teeth of a Gharial, the teeth of Sarcosuchus didn't interlock, so this crocodile was eating sauropods.
