The revision of the Famennian part of the "Late Devonian Standard Conodont Zonation" is based on the in-equivalence between biozones and time, and the rejection of the presumed single phyletic concept on which the previous zonation was based. It is also intended to simplify the zonation, eliminating the zonal groups named after only one taxon, and biozones that are defined by a Last Appearance Datum (LAD). The proposed revision is largely based on the zonation proposed by Ziegler and Sandberg (1990) and is for the most part correlatable using the same zonal markers. Modifications have only been made when strictly necessary, as the aim of the proposal is to maintain the stability of over 50 years of studies. The 22 zones constituting the revised zonation are defined by the First Appearance Datum (FAD) of species or subspecies that have a well-established stratigraphic range and wide geographic distribution. Each zone is named after the taxon for which the FAD defines the lower boundary. For each zone an association of other species useful for its identification is listed.•

“…It is overlain by interbedded limestone, shale and gray‐greenish, clay‐rich, ash. The Devonian–Carboniferous boundary rests near the top of this unit (Malec, , ; Filipiak, ), ~2.2 m above the Hangenberg Shale, at a transition into interbedded black shale (5‐ to 15‐cm‐thick beds) and clay‐rich volcanic ash. Three ash samples were collected for geochronological analysis.…”

High‐precision U–Pb age and duration of the latest Devonian (Famennian) Hangenberg event, and its implications

et al. 2013

Precise U–Pb zircon dates from three volcanic ash beds that bracket the Hangenberg Shale in the Holy Cross Mountains, Poland, constrain the age and duration of one of the most significant palaeobiological events of the Palaeozoic Era, the Hangenberg Event. It is linked to a terminal Devonian global shift from greenhouse to icehouse climate conditions, a global transgression, and widespread black shale deposition. Our results constrain the Hangenberg Event to between 358.97 ± 0.11 Ma and 358.89 ± 0.20 Ma, with a calculated duration of 0.05 +0.14/−0.05 Ma. A third, underlying ash bed yielded a distinctly older age of 359.97 ± 0.46 Ma. The duration of ~50–100 ka. for the event is comparable to those of Quaternary glaciations, and is consistent with both a glacio‐eustatic origin for the eustatic fluctuations and changes in ocean chemistry that led to this major reorganization of the biosphere.

As so ci ate Ed i tor: Leszek Marks An ear lier con cept of the Variscan fore land in Po land (Narkiewicz, 2007) is re con sid ered in the light of new strati graphic, tectonic and geo phys i cal ev i dence, pro vid ing new data on De vo nian sed i men ta tion, Car bon if er ous magmatism and the deep crustal struc ture of SE Po land. Re gional com par i sons with the tec tonic evo lu tion of Cen tral Eu rope and the Black Sea re gion show that the sub si dence pat tern in the fore land was con trolled by al ter nat ing phases of ac cel er ated con ver gence and tectonic stand still along the south ern mar gin of Euramerica. In par tic u lar, the Bretonian (De vo nian/Car bon if er ous) compressional de for ma tion re sulted from in ten si fied orogenic con ver gence in the West-Cen tral European Variscides lead ing to clo sure of the Saxo-Thuringian Ba sin and East-Sudetic back-arc ba sin. An other turn ing point in the re gional tectonosedimentary de vel op ment around the Mississippian-Pennsylvanian bound ary was prob a bly re lated to the ter mi nation of terrane col li sion in the Black Sea re gion. Late Penn syl va nian ba sin in ver sion was as so ci ated with a roughly N-S tectonic short en ing. This was partly due to dis place ment along pre-ex ist ing base ment dis con ti nu ities com pris ing re ac ti vated Cal edo nian su tures that also pre-de ter mined the Devonian-Carboniferous ba sin bound aries. Con se quently, deeply-rooted tec tonic zones, in clud ing the Kraków-Lubliniec and Holy Cross faults and the Teisseyre-Tornquist Zone, fo cussed max i mum compressional and transpressional de for ma tion and as so ci ated up lift. Such a con cept of ter mi nal Variscan tectonism, termed here the "de coup led model", is dis cussed with ref er ence to the re cently pro posed "cou pled model". The lat ter assumes a wide ex tent of the Variscan Orogen, reach ing as far as the mar ginal Radom-Kraoenik Fold-and-Thrust Belt linked with the Bo he mian Mas sif through a ma jor basal de tach ment. It is con cluded that the "de coup led model" is more con sis tent with the doc u mented seis mic and struc tural ev i dence as well as with the pres ent knowl edge of the heterogeneous pre-De vonian base ment in south ern Po land.
