In Butkov Quarry, ammonites of the families Holcodiscidae Spath, 1923 and Barremitidae Breskovski, 1977 occur in the pelagic Lower Cretaceous pelagic deposits of the Manín Unit. This contribution discusses the taxonomy of both families and presents their distribution in the layered sequences of the quarry. The genus Spitidiscus Kilian, 1910 classified as a member of the Superfamily Perisphinctoidea Steinmann in Steinmann and Döderlein, 1890 is an important representative of the Holcodiscidae from a stratigraphic point of view. In areas where the zonal index Acanthodiscus radiatus (Bruguière, 1789) does not occur, as in Butkov Quarry, the first representatives of Spitidiscus indicate the base of the Hauterivian. The genus Plesiospitidiscus Breistroffer, 1947 was long regarded as a member of the Superfamily Desmoceratoidea Zittel, 1895. This superfamily was based on its type species, Eodesmoceras celestini (Pictet and Campiche, 1860), which is not Valanginian in age, as now clearly proven. As a consequence, this superfamily is considered invalid. Vermeulen and Lahondère (2011) proposed an alternative by selecting a suitable initial genus, namely Plesiospitidiscus, for the Family Barremitidae, Superfamily Barremitoidea Breskovski, 1977 (nom. transl. Vermeulen and Lahondère, 2011).

The Aucellina biostratigraphy of the Upper Albian Kirchrode Marls Member succession in the Kirchrode I (1/91) cored borehole is described and the fauna illustrated. The borehole commenced at an unknown depth below the Early Cenomanian marls of the Bemerode Member, but higher beds of the Kirchrode Marls and the basal beds of the Bemerode Member were exposed in the Mittellandkanal and its Stichkanal extension at Misburg. The borehole and surface exposures permit a virtually complete Late Albian succession of Aucellina species to be observed. Published Aucellina range data from the borehole are reassessed and it is suggested that the lower part of the recorded range is based partly on misidentifications of fragments of thin-shelled bivalves such as Syncyclonema and Amussium. Aucellina appears in the borehole succession within the upper part of the Callihoplites auritus ammonite Subzone (Mortoniceras inflatum Zone) and continues to the top of the borehole succession within the Preaeschloenbachia briacensis ammonite Subzone (Stoliczkaia spp. Zone). Aucellina from higher in the briacensis Subzone collected from the Misburg Mittellandkanal section are also discussed and illustrated. There is some evidence that Aucellina occurs typically at levels in the borehole containing predominantly Boreal European Province ammonites, supporting the general inference that Aucellina lived in cooler northern waters. In contrast, Aucellina is poorly represented in intervals with Tethyan ammonites and thin-shelled inoceramids (e.g. the Mortoniceras (Durnovarites) perinflatum Subzone, Stoliczkaia spp. Zone). The briacensis Subzone, with an admixture of Tethyan (Stoliczkaia) and Boreal ammonites contains a distinctive, taxonomically highly diverse Aucellina assemblage. Relevant taxonomic research on European Late Albian and Early Cenomanian Aucellina faunas is reviewed. The Late Albian Aucellina succession in the borehole differs from that established from partially correlative successions in England.

The present study establishes a lithostratigraphic subdivision, a bio- and chemostratigraphy and describes the sedimentology of the Alstatte Bay at the southern margin of the Lower Saxony Basin in northern Germany. The socalled Fischschiefer is developed in the lower part of the section, a 2.1 m thick laminated interval that shows TOC values of up to 2 % and is interpreted as local expression of the global Oceanic Anoxic Event 1a (OAE 1a). The basal part of the Fischschiefer is fairly continuously laminated, whereas its upper part is characterized by an alternation of laminated and non-laminated beds. Stable carbon isotopes ([delta^13]C[carb]) show a characteristic pattern for the Fischschiefer interval that can be correlated with sections from the Tethyan Realm. Immediately above the Fischschiefer, however, the studied section might reveal a diagenetic overprint as indicated by very negative carbon stable isotope values. The remaining part of the section is characterized by a rather monotonous claystone succession, terminated by a greenish layer rich in glauconite overlain by glacial till of Pleistocene age. The fauna is typically Boreal in the lower part of the section, but changes around 2 m above the Fischschiefer towards an assemblage indicating a distinct Tethyan influx. The faunal shift is considered to be due to the maximum flooding of the continuous, long-term sea level rise of the Early Aptian which led also to a supposed shift from a restricted to open bay environment.

The proto-Silesian Basin was well developed within the Alpine Tethys during the Late Jurassic times and existed as undivided entity until the significant Late Cretaceous reorganization. The deposits originated within this basin were incorporated into different structural units: Silesian, Subsilesian and Skole. The calciturbiditic Cieszyn Limestone Formation is the oldest Cretaceous flischoidal sequence of the proto-Silesian Basin. This calciturbiditic sedimentation passed gradually into younger siliciclastic deposition.

Sedimentological development of the Verovice Formation (Czech Moravia) is presented, according to Early Cretaceous geotectonic-eustatic changes in the proto-Silesian Basin. Those processes were a consequence of a gradual rebuilding the architecture of the Alpine-Carpathian realm. The geological events well correspond with the global sequence stratigraphy.

Jednym z celów prężnie rozwijającej się w ostatnich latach geoturystyki jest propagowanie aspektów poznawczych związanych z geologiczną historią Ziemi. W niniejszej pracy zostały zawarte opisy klasycznych polskich stanowisk, w których odsłaniają się najstarsze utwory Karpat Zewnętrznych (fliszowych). Po pierwsze, są to odsłonięcia inicjalnych, basenowych osadów późnojurajsko-wczesnokredowych, reprezentujących wczesne stadia węglanowej sedymentacji fliszowej, odbywającej się w obrębie młodego zbiornika protośląskiego (Goleszów - formacja wędryńska, dolina Soły w Żywcu i Jasieniowa Góra oraz Leszna Górna - formacja wapieni cieszyńskich). Po drugie, są to różnej wielkości izolowane bloki skał wapiennych o olistolitowej genezie zwane skałkami andrychowskimi (Targanice, Roczyny i Inwałd), reprezentujące jurajskie utwory o charakterze rafowym i okołorafowym, powstałe w płytkowodnych środowiskach na podmorskim wyniesieniu Baska-Inwałd.

The popularization of educational aspects linked to the geological history of Earth is one of the goals of geotourism, dynamically developing recently. The present paper contains the description of the classic localities exposing the oldest deposits of the Outer Flysch Carpathians. Firstly, these are initial Late Jurassic-Early Cretaceous basinal facies originated during early carbonate flyschoidal stages within the developing proto-Silesian Basin (Goleszów - Vendryne Formation; Soła River valley in Żywiec and Jasieniowa Mt and Leszna Górna - Cieszyn Limestone Formation). Secondly, these are different size limestone blocks, olistoliths in origin, known as Andrychów Klippen (Targanice, Roczyny and Inwałd) represent Jurassic reef and circum-reef environments originated in shallow-water condition on the Baska-Inwałd submarine ridge.

Praca koncentruje się na elementach ważnych dla zrozumienia paleogeografii Zachodnich Karpat zewnętrznych w późnej jurze i wczesnej kredzie w nawiązaniu do litostratygrafii różnych stref facjalnych i opracowania skał macierzystych tworzących się w tym okresie. Opisano szereg elementów paleograficznych: Tetyda alpejska i basen magurski, grzbiet ślaski, basen seweryńsko-mołdawidzki oraz platforma północnoeuropejska. W obrębie tej platformy wyróżniono strefy wyniesione: grzbiet Baska-Inwałd oraz pawłowska platforma węglanowa, a także strefy basenowe: basen bachowicki i basen mikułowski.

The present paper concentrates on the elements important to understanding the paleogeography of the West Carpathians during Late Jurassic and Early Cretaceous times. These elements are linked to the lithostratigraphy of the various facies zones as well as occurrence of hydrocarbon source rocks. Several paleogeographic elements have been described: the Alpine Tethys, Magura Basin, Silesian Ridge, Severin-Moldavidic Basin and North European Platform. The uplifted and basinal zones were distinguished within the platform. The Baska-Inwałd Ridge and Pavlov Carbonate Platform belong to the uplifted elements, while Bachowice and Mikulov basins represent the basinal zones.

The macrofaunal content of an exceptionally fossiliferous Late Albian core section is described from Zippelsforde in the Brandenburg district in eastern Germany. The main faunal horizon includes among others Euhoplites vulgaris, Mortoniceras (Deiradoceras) albense, Neohibolites minimus, Inoceramus cf. anglicus and Actinoceramus sulcatus. This assemblage indicates a Hysteroceras varicosum Zone, Hysteroceras orbignyi Subzone age. That interval is known from the Anglo-Paris as well as from the Lower Saxony Basin in western Germany, but not was previously recorded from the North East German Basin. Therefore, the record fills a palaeogeographical gap between the Albian in the Carpathians and that of Central Europe. The superjacent interval contains Aucellina gryphaeoides, dating it as latest Albian (Mortoniceras (M.) inflatum Zone, late C. auritus Subzone or younger), and thus indicating a significant condensation within the Late Albian.

W warstwach cieszyńskich odnotowano liczne otwornice bentoniczne wieku tyton-hoteryw. Generalnie ich liczebność i zróżnicowanie taksonomiczne zmniejszały się podczas depozycji tych osadów. Zubożenie zespołów otwornicowych było związane z transformacją geotektoniczną basenu karpackiego (cieszyńskiego) i ewolucją ówczesnych środowisk na przełomie jury i kredy. Analizy morfogrupowa i tafofacjalna wykazały, iż basen ewoluował od marginalnego i szelfowego zbiornika do otwartego basenu morskiego. Proces ten udokumentowała sukcesja ośmiu zespołów otwornicowych. Początkowo dominowały w nich wapienne otwornice bentoniczne znane z szelfowych i pararafowych środowisk basenów epikontynentalnych i morskich. Na przełomie jury i kredy zostały one wyparte przez głębokomorskie otwornice krzemionkowe. Pierwsza grupa wapiennych otwornic miała charakter allochtoniczny i była związana z końcową fazą regresji morza. Odmienna autochtoniczna mikrofauna pojawiła się z początkiem cyklu regresywno-transgresywnego. W tym czasie, przy nadal utrzymującym się niskim poziomie morza, doszło do wyraźnego pogłębienia zbiornika cieszyńskiego. Następstwo omawianych zespołów otwornic określa przynależność paleobiogeograficzną badanego fragmentu zbiornika karpackiego, który stał się integralną częścią oceanu tetydzkiego już we wczesnej kredzie.

Numerous benthic foraminifers are noted in the Cieszyn Beds. Generally their number and taxonomic variability decreased during the sedimentation of these deposits. The impoverishment of foraminiferal assemblages, which corresponded with geotectonic transformation of the Carpathian (Cieszyn) Basin and evolution of the contemporary environments was noted at the turn of Jurassic-Cretaceous. Morphogroup and taphofacial analyses suggest that this basin evolved from narrow, shelf basin into open marine basin. Succession of foraminiferal assemblages has evidenced this process. At the beginning these assemblages contained calcareous benthic forms, which were known from shelf and para-reef environments of epicontinental and marine basins. At the Jurassic-Cretaceous boundary these ones were replaced by deep-water siliceous foraminifers. The first group of the mentioned foraminifers comprised mainly allochthonous forms, which occurred at the end of the regression of the sea. Autochthonous microfauna, al-though differing, appeared at the beginning of transgression cycle. At this time the basin was deepening while a level of the sea was as low as before. The sequence of the studied foraminiferal assemblages is related to paleobiogeographical position of the Cieszyn Basin, which finally became an integral part of the Tethyan bioprovince at the Early Cretaceous.
