I haven't read this specifically, but here is my deduction from what I do know:
Probably some type of mammal-like reptile or archosaur was the first warm blooded vertebrate. As for archosaurs, dinosaurs appear to have been warm blooded, and the heart structure of crocodillians suggests that they evolved from warm blooded ancestors. However, it is likely that a mammal-like reptile evolved a warm blooded metabolism before any archosaur.
