Here is a photo of an alligator's head and an artist's conception of a Tyrannosaurus. The alligator is a modern reptile that is able to keep its nostrils out of the water while swimming because they are raised slightly. It therefore does not have to lift its head out of the water much to swim, and it becomes hidden in the water so it can sneak up on prey. The T. rex has similar nostrils, and may have been able to do the same thing. It may be simple coincidence though.
