The International Conference “Biostratigraphy, Paleogeography and Events in Devonian and Lower Carboniferous” (SDS joint field meeting) to be held in the Novosibirsk (Russia) during 20 July – 10 August, 2011 is dedicated to the memory of Evgeny A. Yolkin.

Main aims of the meeting: 1) to demonstrate reference sections and discuss in the field inter-regional correlation (lithologic and biostratigraphic) levels of Kuznetsk Basin and South Urals Devonian marine basins; 2) brief introduction of reference transitional Upper Devonian-Lower Carboniferous sequences of the Kuznetsk Basin and South Urals Paleozoic marine basins.

Proposal about the conference was approved during the Subcommission on Devonian Stratigraphy and IGCP 499 business meetings in the Kitab State Geological Reserve (Uzbekistan Republic) (September, 2008).

Pre-and Post-conference field excursion “Middle-Upper Devonian And Lower Carboniferous Biostratigraphy Of South Urals And Kuznetsk Basin” will be held in the South Urals and Kuznetsk Basin (south of West Siberia) for an examination of the complete Middle-Upper Devonian and Lower Carboniferous marine sequences in terrigenous, bedded and reef carbonate, as well as volcanic facies with abundant and diverse faunal remains.
