Titanoboa and climate change

NPR on Titanoboa

If ever a creature had a descriptive name, Titanoboa (“Titan snake”) has it. This creature, which lived 60 million years ago, was at one point the largest land animal on earth. (this creature is post-KT event).
One side note to this story of finding this fossil is the climate change aspect:

In this week’s issue of the journal Nature, Head points out that a cold-blooded animal that big would have had to live in a very hot place to survive. According to his calculations, the average temperature would have been about 90 degrees. That’s several degrees warmer than the present-day tropical average and is warmer than scientists believed the tropics ever got, even during ancient periods of greenhouse warming.

It makes sense, if this creature is cold blooded, that given its size that it would need that sort of heat in which to thrive.
