The class of reptilia is broken down into 4 orders (living today).
1) Crocodilia (crocodiles, caimans, alligators, gharials)
2) Testudines (turtles, terrapins, sliders, tortoises)
3) Squamata is broken down into 2 suborders:
a. Lacertila or Sauria (lizards)
b. Serpentes (snakes)
4) Sphenodontia (tuataras)
