I have to ask. Maybe it was in the article, and being me, I missed it. How did they stay warm? Maybe thats not the best way to put it. But seriously, how did they not turn into nessysicles?

Fish are cold blooded and can survive, so these reptiles should've been able to also. Some organisms that live in really frigid waters, like around ice-caps, have the equivalent of anti-freeze in their bodies to prevent ice-crystals from forming. I don't know of anything suggesting marine reptiles would have the same thing though. But, keep in mind, this is a much warmer earth that they were in, little to no ice at the poles.

cold water in australia? well i don't know to much about climate but australia is hot and more hot. any way how did they find them?

Australia was roughly in the area of the south pole at that time. It and India were both attached to Antactica.

Great White Sharks are actually generate their own heat, but not enough to classify them as being warm blooded.

Do they generate their own heat by digesting things?
