The chelonians are the turtles and tortoises. They are an ancient group of reptiles that have a Triassic to Holocene stratigraphic record. Turtles are most easily recognized by their shell - some forms can retract the head & limbs into the shell when threatened, while other species cannot. Their overall body plan has changed very little since the Triassic - a great example of conservative evolution. Chelonians occur in terrestrial, freshwater, brackish-water, and marine settings. Classification: Animalia, Chordata, Vertebrata, Reptilia, Anapsida, Testudines, Cheloniidae See info. at: en.wikipedia.org/wiki/Cheloniidae and en.wikipedia.org/wiki/Turtle |
