A new Devonian oxygen isotope record based on 180 measurements of conodont apatite is reported from South China. The comparison with published ?18Oapatite data shows a considerable offset between records different paleocontinents. This difference can be interpreted by regional variations in salinity, the epicontinental seas having distinctly lower salinity and ?18Oseawater than open ocean due t...

The conodont fauna of the reference succession regional British Llandeilian Stage Llanvirn Series was first described in a classical study by Rhodes more than 65 years ago using single element (form) taxonomy. Although several subsequent authors have recorded substantial number taxa from Llandeilo area, present is to modern taxonomic review these late Darriwilian-early Sandbian faunas that incl...

Conodonts are the most important fossil remains from the largest Phanerozoic extinction as well as the mass extinction of the late Paleozoic and could be used for exact dating during this period. Triassic deposits located in the Elikah Formation contain exposures in most of the Alborz sections as well as the Zal section in northwestern Iran. In this study, the Elikah Formation was investigated ...

Abstract The famous Martenberg section of the eastern Rhenish Massif, Germany, type-section classical Frasnian goniatite and conodont zonations, has been restudied in order to document microfacies development refine stratigraphy around global semichatovae Event/Transgression, proposed level define a future upper substage. More than 8.000 platform elements were identified include new taxa. Palma...
