Morphology and paleoecology

The Mesosauridae train a family of marine reptiles which lived during the Sakmarien, to the lower Permien. These animals of metric size had a muzzle very lengthened and equipped with many conical teeth directed laterally, legs hails and a long laterally compressed tail. They undoubtedly nourished small crustacean (of the notocarididés ) of small size which pullulated in this salt water).

The " Sea with Mésosaures"

Mésosauridés were found exclusively in the " sea with mésosaures" who recovered the South-east of Brazil and the South-west of Africa to the lower Permien. The distribution of mésosaures on both sides of what today is the Atlantic Ocean was used as argument with Alfred Wegener to support his theory of the continental drift.

These animals are known by many skeletons, and trained the majority of the tétrapodes which lived there. The others are represented only by some vertebrae belonging to stéréospondyles.
