Conodonts are very precise tools for global stratigraphic correlation of   Devonian deposits. They can be correlated at the level of standard conodont   zones even for basins having very different geological structure. In this   paper Devonian conodont correlations between north-western margin of the   Kuznetsk Basin (Siberia) and eastern Serbia are demonstrated. The geology of   both regions is quite different. East Serbian zone is the southern tip of the   Carpathian folded area (Carpatho-Balkanides). Middle Paleozoic carbonate and   terrigenous deposits (Silurian, Devonian and Lower Carboniferous) are   replaced by Hercynian molasse, and sedimentation continued throughout the   Mesozoic and Cenozoic Eras. Rocks were exposed to repeatedly tectonic   effects, olistoliths, olistostromes are widespread. Middle Paleozoic   sediments, including Devonian, are localized within separate small tectonic   blocks, often shifted from its place and form allochthons. In the western   part of the Altai-Sayan folded area the Middle Paleozoic sediments have   undergone folding and orogeny during the Hercynian phase of tectonic and   magmatic activity, but since that time the continental conditions have been   dominant in this region. The Devonian deposits are well represented in the   marginal parts of the Kuznetsk Basin. In both regions the Devonian rocks have   been well studied and the standard conodont zones varcus, gigas (rhenana) -   linguiformis, crepida, expansa and praesulcata were established
