Does this mean that modern sharks are not related to megalodons? Or at least not directly?

Not a biologist, but I would think that evolution could take something from cold to warm blooded (or opposite) without way too much time. I think I read somewhere that scientists are debating/speculating whether some dinosaurs were warm blooded as well.
