Conodonts versus Triassic Climatic and Eustatic Changes

From astronomical, sedimentological, paleo-geographical and geochemical points of view, there is a general agreement that the Triassic period was exceptionally warm. The 51 MA long Triassic period started during the Siberian Traps and ended at the height of the Central Atlantic Magmatic Province activity. It is comprised between End Permian and End Triassic mass extinctions. Conodonts survived the former but got extinct by the end of the latter. Three major waves characterise the evolution of Triassic conodonts:I.The 5 MA long Scythian recovery by intensive speciation (23 S/MA);II.The 10 MA long Dinarian of intensive radiation (8.5 S/MA);III.The 16 MA long Julian - Lacian survival (2S/MA) and 20 MA of Alaunian – Rhaetian decline until extinction.
