The structure of turtles different from other amniotes. Introduction: Amniotes evolved from amphibians. The first amniote diverged into Diapsida and Reptilian lineage. The reptilian lineage again diverged into two divisions: Lepidosauria (scaly lizards) and the Archelosauria (ruler turtle). Lepidosauria is further branched in three divisions: Ichthyosaurs (whales), Plesiosaurs, and Squamates (lizards and snake). Archelosauria includes two well-defined biological groups: Testudines (turtles) and Archosauria (crocodilians, dinosaurs, pterosaurs, and birds).
