Systematics of the turtles

from Wikipedia, the free encyclopedia

The turtles (Testudinata, or Testudines, if the crown group is meant; formerly also Chelonia from ancient Greek χελώνιον "turtle") are an order of the Sauropsida . The testudines are divided into two sub-categories.

The Halsberger tortoises , which began to develop during the Jurassic 180 million years ago and are still represented today by ten families, can retract their heads into their shell. The cervical vertebrae of these animals are specially shaped for this purpose, so that the backbone can curve in an S-shape.

The turn-neck turtles , which exist today with three families, are evolutionarily younger, as they first formed in the Chalk . You cannot retract your head like the Cryptodira , but place it sideways under the shell by means of a horizontal S-shaped movement.

In the following classification of the turtles, all recent species are shown as well as the extinct genera that are described in the German-language Wikipedia.
