Ha ha, interesting question. The answer is Tyrannosaurus Rex, Why? because though tyrannosaurus was bigger than an elephant (however it is possible the elephant weighs more) it was still much more agilic, due to the fact it walked on two legs rather than four. And Tyrannosaurus would only have to place one to two bite on the giant mammal to kill it. Some may argue that the elephant would win with its tusks, however the Rex would probably be to quick for the elephant to puncture the large reptile. plus the tyrant could ,under the right circumstances break the tusks off. Well there you have it T-rex vs a elephant. Oh and the same as above goes for a duel between t-rex and a mammoth as well in case you were wondering.

An elephant would crush a crocodile on land and in shallow water. In deep water, the elephant would drown.
The elephant would win.
