The paper describes a new species of the conodont form-genus Neospathodus Mosher, under the specific name N. praekummeli sp. nov. The presently recorded new species has a close morphologic and biostratigraphic relation with the well-known Dienerian guide-species N. kummeli Sweet.

In the Lower Triassic sequence of Spiti the first appearance of N. praekummeli sp. nov. marks the base of Ophiceras bed. It is likely that N. kummeli Sweet has evolved from N. praekummeli sp. nov. near the base of Ophiceras bed.

Abstract


The paper describes a new species of the conodont form-genus Neospathodus Mosher, under the specific name N. praekummeli sp. nov. The presently recorded new species has a close morphologic and biostratigraphic relation with the well-known Dienerian guide-species N. kummeli Sweet.

In the Lower Triassic sequence of Spiti the first appearance of N. praekummeli sp. nov. marks the base of Ophiceras bed. It is likely that N. kummeli Sweet has evolved from N. praekummeli sp. nov. near the base of Ophiceras bed.
