Devonian conodonts from the Foča-Prača Paleozoic complex (Durmitor Nappe, southeastern Bosnia and Herzegovina)

Abstract

Conodont study of the Crna Rijeka borehole CR-17, positioned in the frontal part of the Durmitor Nappe (Foča - Prača Paleozoic complex, SE Bosnia and Herzegovina) is presented. The obtained fauna indicates an Early-Middle Devonian age and due to poor preservation an identification at a generic level is possible only. The recovered conodont elements have a high Color Alteration Index (CAI = 6,5-7) indicating a degree of metamorphism corresponding to a temperature interval from 440 °C to 720 °C.
