Icriodus multidentatus sp. nov. and I. quartadecimensis sp. nov.—New Conodont Species from the Frasnian Stage of the Southern Timan
摘要
Abstract
New species of conodonts of the genus Icriodus—I. multidentatus sp. nov. and I. quartadecimensis sp. nov. are described from the Sargaevian Regional Substage of the Ust’-Yarega Formation (Frasnian Stage, Upper Devonian) of the Southern Timan. The described species have relatively wide platforms, which may be related to the development of a new food resource.
