however, the long, thin snout of "sarcosuchus" was very similar to the thin snouts of the modern gharial, the false gharial and the slender-snouted crocodile, all of which are nearly exclusive fish-eaters and incapable of tackling large prey. this can be contrasted to both the modern nile crocodile and the extinct "deinosuchus", both of which have very broad, heavy skulls, suitable for dealing with large prey. this, coupled with the abundance of large, lobe-finned fish in its environment, leads many to suggest that, far from being a dinosaur killer, sarcosuchus was simply a large piscivore, a scaled-up version of the modern gharial.
