What is the difference between a mammal and a reptile heart?
One key difference is that mammal hearts have four chambers (two atria and two ventricles) while reptile hearts typically have three chambers (two atria and one ventricle). Mammals have a double circulatory system (systemic and pulmonary circulation) while reptiles have a single circulatory system.
Why does a mammal need more oxygen than a reptile of the same size?
Yes, mammals have a 4chambered heart, while reptiles only have a 3chambered heart.
How does a reptile heart work?
Crocodylians, such as alligators, crocodiles, caimans, etc, have four chambered hearts. Testudinidae (turtles), Squamata (amphisbaenians (lizard like), lizards, and snakes), Rhynchocephalia (tuataras); all have two chambered hearts. Hope this helps :)

What were the first warm blooded vertebrates?
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.
