Resumen de Aportaciones al estudio de la recuperación y extinción de los conodontos durante el Triásico

Pablo Plasencia Camps, Ana Márquez Aliaga

• The bigger one Upper Permian Mass Extinction is not affecting to the whole Conodonts and three families over pass de boundary Permian-Triassic. The group show a quick recovery during Early Triassic followed by stabilization during the Middle Triassic. A richness reduction is observed during Early Upper Triassic followed by a light Norian Recovery. The Rhaetian diversity is reduced quickly and its extinction is just before the Triassic end. In this paper we use a Triassic conodont species database to calculate the Origination, Extinction and Growth rates and we discuss our results with other similar works. Conodont Internal Biological causes added by external geological ones could get extinction group to the end Triassic times.
