The role of conodonts in the global stratigraphic correlation on example of southern Siberia (Russia) and eastern Serbia [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2015
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.
