Crocodiles may have had an ancestor that was starting down the path to being warm-blooded. Crocodiles are related to dinosaurs and their modern descendants, birds, which also have four-chambered hearts. The four-chambered heart allows for more efficient blood circulation.

Can a snake have 4 heart chambers?
Pretty much for the same reasons as us - it's simply nature. Dinosaurs also had a four-chambered heart. Unlike mammals, crocodile's right ventricle pumps blood throughout the body. Such a heart perfectly separates blood going to the lungs from that going to the body, which is a requirement for the high blood flow rates and high metabolic rates characteristic of warm-bloodedness. However, living crocodiles are cold-blooded, so it didn't make sense for them to have a warmblooded heart - a mystery!
