The DNA hypothesis suggests that turtles were a sister group to the archosaurs (the group that contains the dinosaurs and their relatives, including crocodiles and their ancestors and modern birds and their ancestors). A second hypothesis posits that turtles were more closely related to lizards and tuataras.

Are crocodiles bulletproof?

Keeping every factor in mind, we can say that a crocodile does not have a bulletproof body, but they can deflect or survive many powerful shots due to the thick layer of skin and bony scales. However, some well-placed shots on their vital parts can kill them immediately.
