Abstract

All specimens assigned by Gorskiy (1932) to the genus Lophophyllum Milne Edwards and Haime, 1850 are revised, redescribed and reillustrated. The corallite identified by him as a second, specifically indeterminate species of Lophophyllum is here questionably included in Amygdalophyllum Dun and Benson, 1920. For the reminding specimens two new, unnamed genera are suggested. ”Lophophyllum” subtortuosum Gorskiy, 1932 belongs to a new, non-dissepimented genus of an unknown family. A possible relationship between gen. nov. 1, sp. nov. 1 and the new Bashkirian genus from the Donets Basin (Ukraine) is proposed.

Abstract

The rugose coral genus Bothrophyllum Trautschold, 1879 is revised on the basis of data from the literature and the author’s personal investigation of both topotypes of its type species B. conicum and related and/or similar taxa from other areas. The intraspecific variability of the type species, its neotype, the intra-generic framework and a new generic diagnosis are established. Many more than 100 taxa related and/or similar to Bothrophyllum were analyzed and the most important of them are discussed. Detailed analysis of the type species based on the neotype and supported by additional topotype specimens illustrated here, allows restriction of both the type species and the genus, and leads to the proposition that Bothrophyllum -like taxa with a shortened cardinal septum should be considered of subgeneric (not named) status. Detailed analysis of the specimens and species described and illustrated from the type site (Myachkovo Quarry, Moscow Basin) form the basis for further considerations. On the basis of that analysis and characters established for the type species, taxa from all other European, African, Asiatic and North American areas either named Bothrophyllum or bearing characters of that genus were analyzed. The supposed origin and discussion of the relationships conclude the paper. A list of synonyms and exclusions from Bothrophyllum and lists of species included, excluded, or possibly belonging to Bothrophyllum and Bothrophyllum -like corals with a shortened cardinal septum are presented.

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. Warszawa

The 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.

Abstract

Four genera (one new, one questionable), seven named species (five new) and five taxa left in open nomenclature are described from uppermost Serpukhovian (Limestone D53) to middle Bashkirian (Limestone G11) strata. A new genus: Nina and the new species: Bothrophyllum kalmyussi, B. gorbachevensis, Nina donetsiana, N. dibimitaria and N. magna are introduced. The genus Cystilophophyllum Fomichev, 1953 is redefined and transferred to the Family Bothrophyllidae. Three general topics discussed in the Considerations are: 1. The taxonomic value of the microstructure of the septa and the necessity for a distinction between that character and diagenetic alterations; 2. Depositional conditions, under which the rugose coral skeletons were deposited; 3. The similarity of skeletal constructions vs. relationships in some taxa of the Subfamily Dibunophyllinae Wang, 1950 and the Family Bothrophyllidae Fomichev, 1953. The lack of final conclusions in the matter of the relationships is due to the incompleteness and restricted number of specimens studied herein and the incomplete investigations of a great majority of the earlier described bothrophyllid taxa.

Abstract

Seven genera (one new), belonging to four subfamilies, seven named species (six new), four species left in open nomenclature and two specimens included in this paper as unnamed Aulophyllidae are described from strata ranging from the lowermost Bashkirian Limestone D5 10 to the lower Bashkirian Limestone F1. A new genus: Voragoaxum and six new species: Dibunophyllum medium, Dibunophylloides columnatus, D. paulus, D. similis, Voragoaxum cavum and Rozkowskia lenta are introduced. Comparison of the ontogeny of the earliest Bashkirian species of Nina Fedorowski, 2017a and Dibunophylloides Fomichev, 1953 suggest the derivation by descent of the Family Bothrophyllidae from the Subfamily Dibunophyllinae. This means that true bothrophylla are absent in the Mississippian strata of the Western European Province and, perhaps, in the contemporaneous strata of other areas as well.

Abstract

Cordibia pumila gen. et sp. nov. (Aulophyllidae, Dibunophyllinae) from the Lower Bashkirian E 1 Limestone of the Donets Basin, Ukraine is described. The term “protocolony” is formally defined as a growth form intermediate between the solitary and colonial. Protocolonies consist of protocorallites and verticils of non-reproductive offsets [i.e., the lost structures]. The early ontogeny of a protocorallite is compared to the blastogeny in the same species in order to establish characters in common during both processes and to document the usefulness of blastogeny for phylogenetic reconstructions. The short duration and abundance of the occurrence (Limestones E1 up acme, E1 1 ) of that species also makes it a good marker for the lowest Feninian (= Krasnopolyanian) strata in the Donets Basin.

Fedorowski, J. and Kullmann, J. 2013. Vojnovskytesidae - a new family of Mississippian Rugosa (Anthozoa). Acta Geologica Polonica, 63(4), 657-679. Warszawa.

Two new species of the genus Vojnovskytes Fedorowski, 2009, namely V. marcinowskii and V. arcuatus, and a new genus, Vojnimitor, based on the new species V. proiectus, all from Mississippian strata of northern Spain, are described. Vojnovskytes variabilis (Vojnovsky-Krieger, 1934), the type species for the genus from the lowermost Visean strata of southern Urals, also is discussed and illustrated. Characters displayed by the taxa mentioned permit introduction of a new family Vojnovskytesidae.

Abstract

Two species, Antiphyllum sp. nov. 1 and Zaphrufimia sp. nov. 1, the first corals found in Štur horizon of the upper Malinowickie Beds, Upper Pendleian (E 1 ), are here described. Additional study of the subspecies of Zaprufimia disjuncta show them to be more similar than previously thought. Although they occur mainly in the Enna and Barbara horizons, one specimen of Z. d. serotina comes from the Gabriela horizon. Biozone Zaphrufimia disujncta disjuncta/Z .d .praematura is proposed for the Enna and Barbara horizons. The subzone of Zaphrufimia/ Triadufimia of that Biozone, defined by the presence of Triadufimia gen. nov., is restricted to the Enna horizon. As confirmed by the occurrence of Cravenoceratoides edalensis, the new subzone roughly corresponds to the E2b1 ammonite Zone. An Antiphyllum/Ostravaia/Variaxon assemblage Zone is proposed for the coral assemblage of the Gaebler horizon. Cravenoceratoides nitidus present in the Roemer band (I b ) shows it to correlate with the E2b2 ammonite Zone. Comparison with other European regions suggests possible faunal exchange between those areas and the Upper Silesian Coal Basin in Serpukhovian time.
