On three rugose coral genera from Serpukhovian strata in the Upper Silesian Coal Basin, Poland

Abstract

ABSTRACT:Fedorowski, J. 2012. On three rugose coral genera from Serpukhovian strata in the Upper Silesian Coal Basin, Poland. Acta Geologica Polonica, 62 (1), 1-33. WarszawaThe rugose coral specimens included by Schindewolf (1952) in the genera Claviphyllum Hudson, 1942, Fasciculophyllum Thomson, 1883 and Pentaphyllum (Tachylasma) Grabau, 1922 are revised on the basis of the original collection. The first two taxa are included in Antiphyllum Schindewolf, 1952, either in its original sense or in its newly introduced subgenus Antiphyllites. The new genus Effigies is introduced for Pentaphyllum (Tachylasma) silesiacum Schindewolf, 1952. The reasons for placing individual genera within given families and suborders are discussed. New, detailed descriptions of species are supplemented by text-figures in order to document their intraspecific variability and phylogenetic relationships.

“…The preserved growth stages are morphologically very similar to C. cornu described by Carruthers (1913), Grabau (1922), Fedorowski (1968), Khoa (1977) and Poty (1981). Also its septal n:d indices (Text-fig.…”

Rugosa (anthozoa) from the serpukhovian (lower carboniferous) of the upper silesian coal basin

“…Bojkowski's (1979) finding of Cravenoceratoides edalensis (Bisat) in the Enna horizon speaks in favour of the lowermost Middle Arnsbergian age for that 'horizon'. Both authors of the present paper accept that age for the Enna despite the earlier opinion of the senior author (Fedorowski 2012b), who followed Czech scientist's idea in placing the Enna in the upper Pendleian. This change of mind stems mostly from comparison of the USCB strata to the revised correlation of the Carboniferous strata in Britain (Waters and Condon 2012;Waters et al 2011) which was not published when Fedorowski's paper was submitted to the Palaeontographica in 2010 (published 2012a).…”

“…Unfortunately, he only mentioned this briefly in the text and did not make a formal revision. Fedorowski (2012b) reinvestigated all the specimens from the USCB potentially belonging to Antiphyllum and discussed possible relatives of this genus and fully accepted Weyer's (1974) revision of the holotype. However, my opinion (Fedorowski 2012, p. 3-5) on the relationships of specimens identified by Schindewolf as Claviphyllum differs from Weyer's (Ibid.…”

“…Thus, specimens with short or absent minor septa in the corallite lumen, such as Claviphyllum hillae Hudson and Fox, 1942 or the specimen described here may belong to Antiphyllum Schindewolf, 1952. This question is discussed more thoroughly in a separate paper (Fedorowski 2012b).…”

“…They reappeared only in the Roemer band, i.e., in the middle of that 'horizon'. Only one specimen, included by Schindewolf (1952) in a new species Claviphyllum magnificum and re-identified by Fedorowski (2012b) . Thus, the position of the assemblage coral zone within the Middle Arnsbergian E2b2 goniatite subzone is well established.…”
