    Opis:
    Starting from a subjective viewpoint on the decreasing interest in invertebrate fossil taxonomy, this essay discusses its importance in palaeobiological studies exemplified with cases from the palaeobiogeography and palaeoecology of rugose corals, and aims at provoking a discussion on the topic. The possible causes of this negative declining trend include inherent problems of palaeontological taxonomy, and changing systems in science and higher education.

    Opis:
    Inconsistency in the approach to the corals included by different authors in the families Tachylasmatidae Grabau, 1928 and Pentaphyllidae Schindewolf, 1942 are discussed in the context of their relationship vs homeomorphy to the Family Plerophyllidae Koker, 1924. Following Schindewolf (1942), the pentaphylloid or cryptophylloid early ontogeny, typical of the former two families, is contrasted with the zaphrentoid ontogeny typical of the latter family. Comprehensive analysis proves the independent taxonomic position of the Suborder Tachylasmatina Fedorowski, 1973. The taxa described herein support this idea. The relationship of the two families: Tachylasmatidae and Pentaphyllidae within the framework of this suborder are suggested. A new genus left in open nomenclature (represented by a single specimen) and three new species, Pentaphyllum sp. nov. 1, ? Pentaphyllum sp. nov. 2 and Gen. et sp. nov. 1 are described from lower Bashkirian deposits.

    Opis:
    The Family Kumpanophyllidae Fomichev, 1953, synonymised by Hill (1981) with the Family Aulophyllidae Dybowski, 1873, is emended and accepted as valid. The new concept of this family, based on both new collections and discussion on literature data, confirms the solitary growth form of its type genus Kumpanophyllum Fomichev, 1953. However, several fasciculate colonial taxa, so far assigned to various families, may belong to this family as well. The emended genus Kumpanophyllum forms a widely distributed taxon, present in Eastern and Western Europe and in Asia. Its Serpukhovian and Bashkirian occurrences in China vs Bashkirian occurrences in the Donets Basin and in Spain, may suggest its far-Asiatic origin, but none of the existing taxa can be suggested as ancestral for that genus. Thus, the suborder position of the Kumpanophyllidae remains unknown. Four new species: K. columellatum, K. decessum, K. levis, and K. praecox, three Kumpanophyllum species left in open nomenclature and one offsetting specimen, questionably assigned to the genus, are described.

    Opis:
    A detailed analysis of the upper Viséan, Serpukhovian and Bashkirian Rugosa of the Donets Basin confirms their Mississippian/Pennsylvanian turnover during the Eumorphoceras / Homalophyllites-Hudsonoceras Zone, as postulated earlier (Fedorowski 1981a). The deterioration of rugose corals, globally diverse in time and space in the late Viséan and Serpukhovian, has resulted in the patchy distribution of survivors and newcomers, present in the Bashkirian. Difficulties in inter-basinal communication and the isolation of some sites have resulted in a different content of Bashkirian Rugosa in particular patches, with only rare genera in common. New data has made it possible to document the appearance of the first late Carboniferous genera in the Donets Basin as early as the lower Voznessenkian Horizon (= lower Chokierian Substage), i.e., close to the beginning of the Bashkirian Stage. The two stages of diversification, established in the Bashkirian rugose corals of the Donets Basin, cannot find their counterparts elsewhere. A palaeogeographic overview of the most important sites of diversified rugose corals documents the need to re-examine many taxa, which should be based on complete specimen studies. This and the precise placement of taxa in the modern stratigraphy must be done in order to make rugose corals globally comparable. Simple repetitions of names, commonly used in general summaries, is strongly misleading in both stratigraphic and palaeogeographic reconstructions.

    Opis:
    The known occurrence of corals distinguished here in the new Family Krynkaphyllidae varies at the subfamily level. Those of the Subfamily Krynkaphyllinae subfam. nov. are so far almost unknown from outside of the Donets Basin. In contrast, those of the Subfamily Colligophyllinae subfam. nov. are common, possibly ranging from the lower Viséan Dorlodotia Salée, 1920, a potential ancestor of the family, to the Artinskian Lytvophyllum tschernovi Soshkina, 1925. They bear different generic names, but were all originally described as fasciculate colonial. A detailed study of Lytvophyllum dobroljubovae Vassilyuk, 1960, the type species of Colligophyllum gen. nov., challenges that recognition in that at least some of those taxa are solitary and gregarious and/or protocolonial. As such, solitary, protocolonial and, probably, fasciculate colonial habits are accepted in the Colligophyllinae subfam. nov., whereas the Krynkaphyllinae subfam. nov. contains only solitary taxa. The resemblance to the Suborder Lonsdaleiina Spasskiy, 1974 led to the analysis of families included in that suborder by Hill (1981) in the context of their relationship, or homeomorphy, to Krynkaphyllidae fam. nov. This question primarily concerns the Family Petalaxidae Fomichev, 1953; a relationship with the Family Geyerophyllidae Minato, 1955, is more distant, if one exists. The distinct, parallel stratigraphic successions of taxa within two subfamilies of the Krynkaphyllidae fam. nov. document their probably common roots and early divergence. However, a lack of robust data precludes an interpretation or treatment of those successions as phylogenetic. The absence of key stratigraphic and morphologic data meant that eastern Asiatic taxa have not been considered in these successions; however, morphological similarities allow for their tentative inclusion within the Krynkaphyllidae fam. nov. The following new taxa are introduced: Krynkaphyllidae fam. nov., Krynkaphyllinae subfam. nov., Colligophyllinae subfam. nov., Krynkaphyllum gen. nov., Colligophyllum gen. nov., Protokionophyllum feninoense sp. nov., Krynkaphyllum multiplexum sp. nov., Krynkaphyllum validum sp. nov., and three species of Protokionophyllum Vassilyuk in Aizenverg et al., 1983 left in open nomenclature.

    Opis:
    Normal marine salinity is the main limiting factor for the Subclass Rugosa. Water depth and temperature are less critical. Individual characteristics of specimens and some characteristics of species are, however, excel-lent environmental indicators. Being distributed exclusively by larvae, Rugosa required free distribution by means of marine currents, as well as midway areas suitable for settlement and metamorphosis of the larvae. Not distance but rather geography and midway environments are therefore the limiting factors for their distribution, relationships and stratigraphic value. Siphonodendron and Siphonodendron-like (“Siphonodendron”) corals are discussed as examples of morphoogical similarity, but not necessarily representing a phylogenetic relationship. The known homeomorphy of European and western North American Siphonodendron taxa (Fedorowski & Bamber 2007) may be extended on the European, some southern Chinese and all south-eastern Australian Siphonodendron-like corals, but only the Chinese and SE Australian forms may be truly related. The latter relationship would extend the boundaries of the Early Carboniferous Australian rugose coral province. The Late Tournaisian age of the earliest Australian “siphonodendrons” indicates an ancestry of the coral fauna within the province (SE Australia and S China).A mechanism for north-westward migration of this fauna, from SE Australia to S China, is not clear.
    Normalne zasolenie mórz stanowi główny czynnik ograniczający występowanie podgromady Rugosa. Głębokość i temperatura wody są mniej istotne. Tym niemniej, poszczególne cechy okazów i niektóre cechy gatunkowe są doskonałymi wskaźnikami środowiska. Rugosa rozprzestrzeniały się wyłącznie w stadium larwalnym. Kolonizacja nowych obszarów była zatem związana z istnieniem otwartej komunikacji morskiej, odpowiednio ukierunkowanych prądów, a w przypadku długich dystansów również z istnieniem pośrednich obszarów dogodnych dla osiadania i metamorfozy larw. Tak więc nie odległość jako taka, lecz układ lądów i mórz oraz warunki ekologiczne na obszarach pośrednich były czynnikami ograniczającymi dla rozprzestrzenienia, pokrewieństw i wartości stratygraficznej Rugosa. Właściwy rodzaj Siphonodendron i koralowce podobne do tego rodzaju („sifonodendrony”) zostały w tym artykule przedyskutowane jako przykład podobieństwa morfologicznego, ale niekoniecznie pokrewieństw filogenetycznych. Homeomorfia europejskich i północno-amerykańskich taksonów (Fedorowski & Bamber2007) może zostać przeniesiona również na europejskie oraz niektóre chińskie i wszystkie australijskie „sifo-nodendrony”. Tylko gatunki z ostatnich dwóch obszarów mogą być rzeczywiście spokrewnione. Pokrewieństwo to rozszerzyłoby granice wczesnokarbońskiej prowincji australijskiej (SE Australia i S Chiny). Późnoturnejski wiek najstarszych „sifonodendronów” australijskich wskazuje na ich pozycję wyjściową w obrębie prowincji. Mechanizm rozprzestrzeniania się tych faun ku północnemu zachodowi, z SE Australii do S Chin, pozostaje niejasny.

    The Family Neokoninckophyllidae and its type genus Neokoninckophyllum Fomichev, 1939 (type species: N. tanaicum Fomichev, 1939) are discussed and emended. In addition, the genera Orygmophyllum Fomichev, 1953 and Yuanophylloides Fomichev, 1953, originally included in the Families Campophyllidae Wedekind, 1922 and Lophophyllidae Grabau, 1928, respectively, are emended as well and transferred to the Neokoninckophyllidae. Two early Bashkirian species, viz. Yuanophylloides rectus (Vassilyuk in Aizenverg et al., 1983) and Y. inauditus (Moore and Jeffords, 1945), and the Moscovian Neokoninckophyllum sp. nov. are described on the basis of new collections from the Donets Basin. Neokoninckophyllum tanaicum, Yuanophylloides gorskyi Fomichev, 1953 (both Moscovian in age) and Y. cruciformis Fomichev, 1953 (latest Bashkirian), are redescribed on the basis of peels taken from Fomichev’s (1953) type specimens. Derivation of the Family Neokoninckophyllidae from the Subfamily Dibunophyllinae Wang, 1950 is postulated and phylogenetic links within the former are hinted at. The occurrence of Yuanophylloides inauditus in both the Donets Basin and the Western Interior Province of North America points to marine communication between those areas during the Bashkirian. The slightly earlier appearance of the oldest neokoninckophyllids in the Donets Basin, in comparison to North America (i.e., R1 vs R2 ammonoid biozones), documents the common roots and monophyletic development of the Neokoninckophyllidae in both areas.

    Opis:
    A new Subfamily Dirimiinae of the Family Kumpanophyllidae Fomichev, 1953 is introduced on the basis of Dirimia gen. nov., which is represented by six new named species and three species left in open nomenclature. The new species are Dirimia multiplexa, D. similis, D. recessia, D. composita, D. extrema, D. nana, Dirimia sp. 1, Dirimia sp. 2 and Dirimia sp. 3. The progressing atrophy of the columnotheca, leading to its total reduction in extreme species, and the occurrence of an axial structure instead of a compact pseudocolumella established in these species are accepted as differences exceeding the genus level. All specimens assigned to this subfamily were derived from the same Limestone F1 of the Donets Basin, and mostly from the same locality. The reasons for their split into a relatively large number of species are: 1) an increased radiation typical for faunal turnover times; 2) a delay in the appearance of differentiated skeletal characters relative to the appearance of genetic differences large enough to characterise different species; 3) a bias in preservation of fossil remnants by comparison to living populations, amplified by biases in the collections available for study by comparison to the total number of specimens fossilised.

    Opis:
    The full-time studies in geology started in Poznaň in 1919, i.e.when the Piast University (Wszechnica Piastowska) were established, soon after renamed to the Poznań University. Three institutes, namely Geology, Mineralogy and Palaeontology, were created. Scientists employed in those institutes produced nearly 8% of all papers in geology, published in Poland before the Second World War. Already in the academic year 1945/1946, a very small teaching team, lead by Professor K. Smulikowski, re-established the full-time studies in geology at the Poznań University, active until 1952. Only 18 students were able to receive their MSc degrees during that time. From 1952 to 1988, the full-time studies in geology were suspended. The small Chair of Geology offered courses in geology for biology and geography students first, and exclusively for geography afterwards. However, the scientific personnel of the Chair was very active in scientific investigations and publishing. Eight persons, five of them from the outside, received their PhD degrees in geology and palaeontology from the Chair. The intensive effort, started in 1987, resulted in the re-establishment of the full-time studies in Geology at Adam Mickiewicz University in the academic year 1988/1989. Following that important event and thanks to the full-time employment of several outstanding professors in geology, mineralogy, hydrogeology and palaeontology, the Chair of Geology was elevated in November 1990 to the level of the Institute of Geology. In 1992, the Institute of Geology received its permanent seat occupied to date. In 1994, the first geology students were graduated. From that time and until 2019, we graduated 378 BSc, 1017 MSc, 72 PhD and 23 DSc (habilitation), and 11 scientists received the scientific title of full professor.
