Megalodon Once Ruled the Oceans, But Not Antarctica

Megalodon was one of the biggest creatures ever to roam the Earth. It was longer than your average school bus and could easily weigh more than 10 elephants combined. In terms of its location, the megalodon lived practically in all waters on our globe, except near the poles. The reason why there were no megalodon teeth found in Antarctica is probably that the gigantic creature adapted to only warm tropical and subtropical waters. Could that be the reason it is extinct today?
