    Opis:
    This study describes the megaspore assemblages from the Ryabinsk Member of the Vokhma Formation of the Moscow Syneclise. The genus Otynisporites is emended, three new species, Maexisporites meditectatus, M. rugulaeferus and Otynisporites maculosus, are erected, and one new combination, Maexisporites grosstriletus, is proposed. Megaspore descriptions relate the gross morphology and fine structure of the exine surface of thirteen taxa. From the appearance of the exine surface and ornamentation processes, it appears that some forms currently included in certain genera according to their morphological features do not belong to them. The assemblage from Sholga is evidently of low diversity at the generic level, possibly reflecting the end-Permian biotic crisis. The composition of the megaspore assemblages indicates their Induan age.megaspores taxonomy palynostratigraphy Triassic Induan Russia

    Opis:
    If ichnotaxonomy is to be scientific, then its results must be repeatable. While some ichnotaxa are identified consistently, others are not, suggesting that ichnotaxonomy is not a mature science. When researchers disagree on the identification of a specimen, it suggests that closer examination is needed: an intermediate stage in the scientific method. But when ichnologists publish different names for the same trace fossils, multiple trials of classification have yielded different results, suggesting a failure of the hypotheses that led to the names. The burgeoning of invertebrate ichnology from the 1960s onward was made possible by demonstrating its utility to the petroleum industry; in part, this was accomplished by simplifying the ichnotaxonomy of common trace fossils to the point where a specialist was not required to make use of them in sedimentology and stratigraphy. The biological aspect of trace fossils, albeit of great interest, was downplayed in favour of a severely geometric approach. Ironically, this has had the effect of obscuring basic relationships of trace fossils and their palaeoenvironments that could be of great use to sedimentologists. Previous researchers have emphasized the value of a uniform approach in ichnotaxonomy. To accomplish this, ichnologists should take inspiration from the taxonomy of body fossils. Making ichnotaxonomy more replicable will take time and effort among investigators. In the long run, this can be accomplished by a holistic approach that includes close observation of trace fossils, standardized procedures of description and diagnosis, reinvestigation of type material, attention to bioprint (morphological traits that reveal the anatomical and ethological characteristics of the tracemakers; Rindsberg and Kopaska-Merkel, 2005), avoidance of taphonomic and human bias, and above all, cooperation.

    Opis:
    The Prosopidae is an extinct family, consisting mostly of Mesozoic species. Most probably it accommodates the ancestors of all brachyurans in the large sense. The family appeared in the Late Pliensbachian and disappeared at the Early Palaeocene. Evolution of the Prosopidae, and therefore, brachyuran evolution started on Middle Jurassic, shallow, soft bottom marine environments. The world-wide Callovian transgression made possible the formation of bioherms and reefs in the Late Jurassic, creating ecological niches for the rapidly differentiating prosopids. These crabs migrated rapidly all over Europe in the Oxfordian and began to flourish and massively occupied sponge megafacies from Portugal to Poland. In the Kimmeridgian, the area of known prosopids shrank, which has probably been connected with decreasing of the reef facies. In turn, a Tithonian regression in the per-Tethyan area resulted in changes of habitats and in colonisation of the coral reefs. When reef facies retreated at the Jurassic-Cretaceous boundary, the favourable conditions for crab development also vanished, so the known Cretaceous prosopids are rare and spatially dispersed. In Tertiary, the closely related descendants of them, homolodromiids, inhabited preferably soft muddy bottoms in deeper, colder waters.
    Kraby z rodziny Prosopidae, reprezentowane są prawie wyłącznie przez gatunki mezozoiczne. Z filogenetycznego punktu widzenia, są one prawdopodobnie przodkami wszystkich pozostałych gatunków krabów. Przedstawiciele tej rodziny znani są od późnego pliensbachu do wczesnego paleocenu. Ewolucja prosopidów, a poprzez to ewolucja pozostałych krabów, rozpoczęła sią w środkowojurajskich, płytkich środowiskach morskich o miękkim charakterze dna. Ogólnoświatowa transgresja kelowejska stworzyła dogodne warunki do powstania różnorodnych bioherm i raf w późnej jurze, które stanowiły nisze ekologiczne dla szybko różnicujących się dzięki temu krabów z rodziny Prosopidae. Kraby te migrowały gwałtownie na całą Europę w oksfordzie, masowo zasiedlając megafację gąbkową i są obecnie znajdowane w utworach tej facji od Portugalii do Polski. W kimerydzie obszar występowania prosopidów wyraźnie się skurczył, co było prawdopodobnie związane ze stopniowym zanikiem tej facji. Z kolei w tytonie regresja w obszarach perytetydzkich spowodowała zmianę środowiska życia krabów i kolonizację przez nie raf koralowych. Dogodne warunki dla rozwoju tych krabów gwałtownie się pogorszyły blisko granicy jury i kredy (zanikanie facji rafowych) skutkiem czego kredowe prosopidy są rzadkie i geograficznie rozproszone. W trzeciorzędzie najbliżsi potomkowie rodziny Prosopidae - kopalni przedstawiciele rodziny Homolodromiidae - zasiedlili środowiska miękkich den głębszych i zimniejszych mórz.

    Shallow-water scleractinian corals from Cretaceous allochthonous sediments of Subpelagonian Zone in Agrostylia (Parnassos region, Central Greece) represent 47 taxa belonging to 35 genera, 15 families and 8 suborders; of these 3 new genera and 9 new species are described. Among these taxa, 5 were identified only at the generic level. One octocorallian species has also been identified. This coral assemblage is representative for late Early Cretaceous Tethyan realm but also shows some endemism. A characteristic feature of this scleractinian coral assemblage is the abundance of specimens from the suborder Rhipidogyrina. The Albian age of the corals discussed is indicated by the whole studied coral fauna, associated foraminifers, calpionellids and calcareous dinoflagellates

    Opis:
    Hexactinellid sponges are extremely abundant in the basal sequence of the Santonian of the Kraków region. This is the only known area in Poland where Santonian deposits with sponges are exposed. The studied sponges are redeposited and probably represent a Santonian or/and Coniacian assemblage. They inhabited a quiet, deeper part of the epicontinental sea that covered the southern part of Poland in Late Cretaceous times. This paper is a taxonomic revision of sponges collected from this region by the late Prof. J. Małecki. Based on existing old collections and newly collected material comprising 1020 specimens, 34 species have been described, including 14 belonging to the Hexactinosida and 20 to the Lychniscosida. All sponge species occurring in the Santonian succession of the Kraków area are also known from various Late Cretaceous sponge assemblages of Europe. Five species described, i.e. Eurete halli (Schrammen), Lefroyella favoidea Schrammen, Spirolophia tortuosa (Roemer), Coeloptychium lobatum Goldfuss, and Wollemannia araneosa Schrammen have not been so far noted in pre-Campanian deposits. The examined assemblage is particularly similar to the sponge fauna from the Middle Coniacian - Middle Santonian deposits of England and from the Lower Santonian of Russia (Saratov area).

    Opis:
    Siliceous sponges are extremely abundant in the Upper Campanian-Maastrichtian opokas and marls of the Middle Vistula River Valley, situated in the western edge of the Lublin Basin, part of the Cretaceous German-Polish Basin. This is also the only one area in Poland where strata bearing the Late Maastrichtian sponges are exposed. The presented paper is a taxonomic revision of sponges collected from this region. Based both on existing and newly collected material comprising ca. 1750 specimens, 51 species have been described, including 18 belonging to the Hexactinosida, 15 - to the Lychniscosida and 18 - to Demospongiae. Among them, 28 have not been so far described from Poland. One new genus Varioporospongia, assigned to the family Ventriculitidae Smith and two new species Varioporospongia dariae sp. n. and Aphrocallistes calciformis sp. n. have been described. Comparison of sponge fauna from the area of Podilia, Crimea, Chernihov, and Donbas regions, as well as literature data point to the occurrence of species common in the analysed area and to the basins of Eastern and Western Europe. This in turn indicates good connections between particular basins of the European epicontinental sea during the Campanian-Maastrichtian. Analysis of the taxonomic composition of the Middle Vistula assem- blage suggests that the occurring sponge fauna is transitional between the faunas of Eastern and Western Europe, what may be linked with the central location of the Lublin Basin in the European epicontinental sea. The gradual upward decrease of taxonomic diversity of the Hexactinosida and Lychniscosida in the studied succession points to gradual basin shallowing, what is consistent with the global regressive trend by the end of the Cretaceous. The domination of the Hexactinellida over the lithistids in terms of diversity and abundance in the entire section allows us to estimate the maximum depth of the Late Campanian basin as 200-250 m and to constrain the minimum depth during the latest Maastrichtian as about 100 m.

    Opis:
    Similarities between scleractinian corals from extinct suborders Pachythecaliina Eliášová 1976 and Rhipidogyrina Roniewicz 1976 are discussed. Corals of the former suborder are considered by some authors as possible descendants of Palaeozoic Rugosa because of their unusual skeletal characters. Some rhipidogyrinans, especially the family Aulastraeoporidae, despite their different septal microstructure, share more common features with pachythecaliinans than with other scleractinians. The following skeletal features are discussed to show similarities between these two suborders: (1) wall microstructure and its relations to septa, (2) corallite bilateral symmetry, (3) marginarium, (4) lonsdaleoid and apophysal septa, and (5) internal septal margin. These similarities can be explained by convergence, although phylogenetic relationships of both suborders can not be excluded. This hypothesis needs to be verified by more studies, especially on early blastogeny of rhipidogyrinans and wall microstructure of pachythecaliinans. The systematic part gives descriptions of the discussed coral suborders occuring in the Štramberk-type limestones, the Polish Outer Carpathians (Tithonian-?Berriasian, ?Valanginian). Similarly as in the Štramberk Limestone (Moravia), pachythecaliinans are highly diversified (17 species, 12 genera, including Pachythecophyllia eliasovae n.gen., n.sp.). Rhipidogyrinans are represented by 4 species of 4 genera, including ?Ogilvinella morycowae n.sp.

    Opis:
    Diversified and abundant corals of the suborder Pachythecaliina (order Hexanthiniaria) are described from Upper Barremian, biostromal reefs of the Emen Formation, Lovech Urgonian Group, north central Bulgaria. The corals are mostly of the phaceloid growth form and represent 14 species (six new), 12 genera (three new), belonging to five families. Pachythecaliines occur with the small, monopleurid cylindrical rudist Mathesia darderi. The rudists frequently are densely clustered, occur between coral branches or are in contact with them. Other corals, with the exception of the phaceloid Calamophylliopsis, and other rudists, are rare. Non-laminated microbialite crusts provided additional, structural support for bioconstruction development. Microbialites (automicrites) can be interpreted as a product of microbial activity, or alternatively, as a result of carbonate precipitation, brought about by non-living organic substrates (organomineralization s.s.). In addition to microbialites, metazoans are encrusted by heterotrophic skeletal microorganisms, while photophilic and oligotrophic microencrusters, usually common in other coral-bearing limestones of the Emen Formation, are very rare. The section at the Rusalya Quarry (NW of Veliko Tarnovo), about 42 m thick, provides the sedimentary and environmental context for the reefal biostromes. The vertical biotic and sedimentary succession displays a general shallowing trend: from the outer carbonate platform with bioclastic limestones containing small boundstone patches (corals, but not pachythecaliines, Lithocodium aggregatum), to the inner platform with rudist biostromes. The pachythecaliine-rich biostromes, 2.5 m thick, were developed in a low-energy environment, referred to the distal part of the rudist-dominated area of the platform. The development of microbialites was facilitated by a low sedimentation rate, and possibly by increased nutrient level. Only poorly diversified and non-phaceloid pachythecaliines occur in other coral-rich limestones and marls of the Urgonian complex in Bulgaria. The assemblage described is the most remarkable, Early Cretaceous coral community worldwide, with regard to pachythecaliines. Phaceloid pachythecaliines are only more common in the Upper Jurassic rocks, being particularly diversified in the Tithonian–Lower Berriasian Štramberk Limestone (Czech Republic) and its equivalent in the Polish Outer Carpathians. However, their sedimentary context differs from that described for the corals of the Emen Formation.

    Opis:
    The genus Cyathophora Michelin, 1843 (Cyathophoridae) is removed from the suborder Stylinina Alloiteau, 1952 and transferred to the Stylophyllina Beauvais, 1980. Morphologically, it differs from stylinine corals in that rudimentary septa are developed in the form of ridges or spines on the wall and may continue onto the endothecal elements as amplexoid septa. Relics of primary aragonite microstructure, preserved in silicified colonies of Cyathophora steinmanni Fritzsche, 1924 (Barremian–early Aptian) and in a calcified colony of C. richardi Michelin, 1843 (middle Oxfordian), indicate a non-trabecular structure of their skeletons. The sclerenchyme of radial elements is differentiated into fascicles of fibres, and in the form of fascicles or a non-differentiated layer of fibres, it continues as the upper part of endothecal elements and as the incremental layers of the wall. A micro-lamellation of the skeleton corresponds to the accretionary mode of skeleton growth found in Recent corals. A similarity between the septal microstructure of Cyathophora and that of the stylophyllid genera, the Triassic Anthostylis Roniewicz, 1989 and the Triassic–Early Jurassic Stylophyllopsis Frech, 1890, is interpreted as a result of their being phylogenetically related. The microstructure of the Jurassic Stylina gaulardi Michelin, 1843 has been considered for purposes of comparison. The systematics of the genus Cyathophora is formally revised with C. richardi Michelin reinstated as the type species.

Among them four have not previously been noted in this area. Two species, Astropegma stellata (Roemer, 1840) and Leiostracosia robusta (Schrammen, 1902) are reported from Turonian strata for the first time. The occurrence of ventriculitid sponges in the Upper Turonian–Lower Coniacian succession of the Opole Trough indicates a soft- bottom, calm-water environment, with depths below the storm-wave base and a low rate of sedimentation.

    Opis:
    About twenty species of scleractinian corals are known from the shallow marine epicontinental deposits (Middle Triassic: Anisian, Muschelkalk) of Kraków-Upper Silesia region. Four of them require taxonomic revision. On the basis of partly preserved micromorphological features and the microstructure of the skeletons two of them are corrected, i.e. Coelocoenia? assmanni Weissermel, 1925 and C. exporrecta Weissermel, 1925, from Kamień Śląski, near Opole (Upper Silesia). Coelocoenia? assmanni was incorporated into Eckastraea prisca (Weissermel, 1925), family Eckastraeidae Morycowa, 2006, in Morycowa and Szulc (2006) and C. exporrecta is assigned to a new genus Opolestraea nov. gen., family Eckastraeidae.

    Opis:
    A revision of a major part of the old collections of Upper Devonian goniatites from the Holy Cross Mts., collected by J. Czarnocki, H. Makowski and M. Różkowska, is presented. Described and illustrated are 26 species and subspecies belonging to 20 genera and subgenera and 9 families. Studied and illustrated for the first time are 35 suture lines and 15 growth lines. Conodonts, mostly collected from the parent rocks of the studied goniatites, allow for a more precise correlation of these goniatites with standard ammonoid and conodont zonations. The museum collections studied incude specimens mostly of all standard Upper Frasnian through Famennian ammonoid zonations, but the precise zonal boundaries could not be established. Goniatite assemblages from the Płucki and Janczyce sections correspond to the linguiformis and Upper crepida conodont zones, respectively. Moreover, four conodont zones have been distinguished in the Łagów (Dule) section: Upper crepida/rhomboidea, Lower marginifera, Lower/Upper marginifera and trachytera zones. This last zone has been recognised here for the first time.
