“…In the latter group, the problematical interval of the late Arnsbergian to Alportian is represented only by one biozone ( L. subtriquetra–K. ornatus Zone), which was defined in the Stonehead Beck section (Owens et al ., ). Some of the data permit different interpretations and correlations, because, as in Russia and the Ukraine, many of the foraminifers recorded in those limestones are usually considered as markers for the Bashkirian, but rarely and sparsely, they are also recorded from the uppermost late Serpukhovian.…”

“…), which might contain, at least in part, this supposed gap. Unfortunately, there is no other fossil group which allows us to calibrate the foraminiferal database in the studied sections, because ammonoids are absent, conodonts have not been studied and palynology data either have insufficient resolution (Owens et al ., ) or suggest younger ages (e.g. Stephenson et al ., ).…”

A detailed study of foraminiferal assemblages recorded in limestones from northern England in the Stainmore Trough and Alston Block permits their assignment to different European substages than in previous studies. Comparisons with foraminiferal assemblages, mostly from Russia, allow the biozonations to be correlated with the Viséan, Serpukhovian and Bashkirian international stages, as well as with the Russian (and Ukrainian) substages for the Serpukhovian (Tarussian, Steshevian, Protvian and Zapaltyubian). The Scar Limestone and Five Yard Limestone Members are assigned to the Tarussian and, thus, represent the lowermost part of the formal Serpukhovian Stage. This new correlation coincides closely with the first occurrence of the conodont Lochriea ziegleri from levels equivalent to the Single Post Limestone that could potentially form the revised base for the Serpukhovian. The Three Yard Limestone Member is correlated with the base of the Steshevian substage which also includes the Four Fathom Limestone Member, Great Limestone Member and Little Limestone. The base of the Protvian is considered to lie within the Crag Limestone, whereas the Rookhope Shell Band contains foraminiferal assemblages more typical of the Zapaltyubian in the Ukraine and Chernyshevkian in the Urals. Assemblages of the Upper Fell Top Limestone and Grindstone/Botany Limestones contain foraminiferal species that have been used for the recognition of the Bashkirian elsewhere. There is no other fossil group which allows the calibration of those foraminiferal assemblages, because ammonoids are virtually absent in the shallow‐water cyclothemic successions and conodonts have not been studied in detail in this region. The Mid‐Carboniferous boundary and the Voznessenian substage might be reasonably located below the Upper Fell Top Limestone. Copyright © 2015 John Wiley & Sons, Ltd.

In this study of Mississippian rocks in Ireland, it is now recognized, based on faunal evidence, that several upper Viséan limestone formations which were previously excluded from the Serpukhovian now belong, in part, to the lower two substages of the Serpukhovian. A reassessment of previous foraminiferal determinations, together with new foraminiferal data, has confirmed that rocks equivalent to the Tarusian and Steshevian substages are present in several sections. In the Slievenaglasha Formation and Magowna Formation (County Clare) and Deer Park Formation (County Meath), Tarusian and Steshevian foraminiferal assemblages are thus recorded. In the Clogrenan Formation (County Carlow), Carganamuck Limestone Formation (County Armagh) and Rockdale Limestone Formation (County Tyrone), Tarusian foraminiferal assemblages are recorded in the upper beds of thick limestone successions. Key foraminiferal and algal taxa characterize each assemblage, which have been correlated with equivalent Serpukhovian strata in the north of England and Scotland. A three‐stage evolution is recognized in archaediscid foraminifers: from Neoarchaediscus gregorii, followed by Neoarchaediscus postrugosus form 1, and N. postrugosus form 2, with Neoarchaediscus postrugosus form 1 used to define the base of the Serpukhovian. The recognition of Tarusian and Steshevian foraminiferal assemblages implies that areas of shallow‐water platform carbonate sedimentation in Ireland during the upper Viséan (Brigantian) persisted into the Early Serpukhovian.
