the present work aims to demonstrate the importance of Taphonomy applied to the studies of the Permo-Triassic paleovertebrates and to emphasize the influence that the taphonomic processes has as a source of information about the fossil vertebrates. It also aims to demonstrate the need for a review, in the light of new known theophonies, of the fossiliferous content hitherto recorded for sequences containing fossil vertebrates from those periods
