Alligator big enough to fight a Tyrannosaurus

While you are correct about the dinosaur being a tyrannosaur, it's not a T. Rex. It's an Albertosaurus, a slightly smaller relative (big individuals could become up to 4 meters in height, 10 meters in length and 3 tons in weight). Deinosuchus could become up to 12-13 meters long and weigh up to 8.5 tons.

My username suggestion for you is "The Banisher".

While I am a big fan of alligators, I'm a bigger fan of the gharial.
