Carbon isotope values in conodont elements from the latest Devonian–Early Carboniferous carbonate platform facies (Timan-Pechora Basin)
The δ13Corg values and their variations in conodont elements of the latest Famennian–Tournaisian species Polygnathus parapetus Druce are considered. The conodonts studied come from the latest Famennian–Tournaisian interval of the Kamenka River section (Timan-Pechora Basin). The carbon isotope compos...
