Abstract

Abstract

Oktavites spiralis (Geinitz, 1842) is an index graptolite species of the Telychian age (late Llandovery, Silurian) that combined marked spiral morphology as well as a global distribution, making it stratigraphically significant. However, the first appearance datum of Oktavites spiralis is controversial, and consequently it is much difficult for regional stratigraphic correlations. In the Ziyang-Langao area of Shaanxi Province, Oktavites spiralis graptolite zone belongs to an abundance zone, rather than the FAD (first appearance datum) of this index fossil. Recent investigations in multiple Telychian profiles in the Ziyang-Langao area, along the northern margin of South China, reveal that a new species Oktavites longtanensis sp. nov. can be further distinguished from typical form of Oktavites spiralis and Oktavites contortus according to the larvas and coiled model. The new species Oktavites longtanensis sp. nov. is of a shorter stratigraphic range with great evolutionary significance, therefore has a great potential for accurate correlation of Oktavites spiralis Zone.
