Diagram of the origins of the turtle body plan through the Triassic: isolated bony plates evolved to form a complete shell, in a sequence involving Pappochelys, Eorhynchochelys, Odontochelys, and Proganochelys. [19] Zoologists have sought to explain the evolutionary origin of the turtles, and in particular of their unique shells.
