    Opis:
    The author has completed a palaeoecological analysis of assemblages of ostracods, collected from the sections of the Berriasian deposits of central Crimea. The strata belonging to this stage are divided into four formations, and these into stratigraphic subdivisions of member rank, numbered 1–29. The members accumulated in deeper and shallower environments in a shallow marine basin, and are distinguished on the basis of the characteristic features of the composition of the ostracod complexes. Changes of temperature conditions and water mobility were identified.

    Opis:
    The latest Ordovician is marked by a severe climate change, the Hirnantian glaciation. This climatic event affected many marine taxa including ostracods. Rich and abundant ostracod assemblages of the Baltic Palaeobasin were severly impoverished. Many of the typical pre-Hirnatian warm-water ostracod species died out, but also some distinct, cold-water species appeared. Two very different but likely coeval latest Ordovician ostracod assemblages are recorded in the Baltic countries and north-eastern Poland. The latest Ordovician Estonian Shelf (inner ramp) is characterized by the Medianella aequa association whilst sections in the Livonian Basin (middle to outer ramp) reveal the Harpabollia harparum association that is thought to represent a cold-water assemblage belonging to the Dalmanitina-Hirnantia Fauna sensu lato. A transitional assemblage composed of a “species mixture” of typical Hirnantian cold-water and some pre-Hirnantian warm-water ostracod species is described for the first time from the Kętrzyn IG1 borehole, north-eastern Poland. The assemblage is dominated by Cryptophyllus pius sp. n. The genus Cryptophyllus is rare in the two other well-known assemblages. The discovery suggests that marginal parts of the Baltic Palaeobasin could serve as a kind of refuge for the last representatives of the ostracod faunas of the inner shelf of Baltic Palaeobasin. The Hirnantian assemblage is replaced by the low-diversity recovery assemblage that is dated as late Hirnantian-Silurian in Estonia and other areas. This suggests that the position of the systemic boundary in the Kętrzyn borehole and elsewhere in north-eastern Poland should be re-evaluated.

    Opis:
    The Berriasian deposits of the central Crimea have been studied in order to compose a composite sequence of the stage with detailed palaeontological characterization. The Berriasian includes the Bedenekyrskaya Formation (packstones), Bechku Formation (siltstones, sandstones) and Kuchkinskaya Formation (sponge packstones, clays, siltstones, and coral-algal bioherm framestones). The Jacobi, Occitanica and Boissieri zones were identified based on ammonites found in the sections. A micropalaeontological analysis determined the following: 6 foraminiferal assemblages, the Costacythere khiamii – Hechticythere belbekensis and Costacythere drushchitzi – Reticythere marfenini ostracod assemblages, and a Phoberocysta neocomica dinocyst assemblage. Palaeoecological analysis of the ostracod and foraminiferal associations indicates a moderately warm marine basin with normal salinity and shallow depths (tens of meters). Only the sponge horizon was probably deposited in a deeper-water environment.

    Opis:
    The paper give a biostratigraphic interpretation of the Emsian to Eifelian in the Łysogóry and Kielce regions of the Holy Cross Mountains, based on the different groups of microfossils: miospores, conodonts, ostracods and foraminifers. Four miospore zones were identified in the uppermost Pragian, Emsian and lowermost Eifelian: Verrucosisporites polygonalis-Dibolisporites wetteldorfensis (PW), Emphanisporites annulatus-Brochotriletes bellatulus (AB), Emphanisporites foveolatus-Verruciretusispora dubia (FD) and Acinosporites apiculatus-Grandispora protea (AP). In the Łysogóry region, the Emsian and lowermost Eifelian comprises four cono-dont zones: serotinus,patulus,partitus and costatus, three ostracod assemblages and several foraminifer assemblages. In the Kielce region, deposits from the Emsian/Eifelian boundary interval yield conodonts from the patulus and partitus zones, two ostracod assemblages and assemblages of agglutinated foraminifers. The joint biostratigraphic analysis allows a tentative correlation of the lithostratigraphic units from both areas. It also provides independent control/calibration on the different biostratigraphical systems. The Pragian/Emsian boundary is located in the lower part of the Barcza Formation and in the lower part of the Haliszka Formation, whereas the Emsian/Eifelian boundary lies in the upper part of the Grzegorzowice Formation and in the upper part of the Winna Formation.

    Polish Geological Institute
    Opis:
    Micropalaeontological Laboratory at the Polish Geological Institute in Warsaw was organized by Władysław Pożaryski in 1947. The studies were going towards the development of regional micropalaeontological stratigraphic schemes of Mesozoic deposits of Poland (excluding the Carpathians) and dating rocks, based on micropalaeontological analyses. Results of examination of a huge number of samples (over 90,000) have been the basis for biostratigraphical reports and monographs, diagnoses of many new taxa, and over 1000 archival collections of Mesozoic, Paleogene and Neogene microfaunas. The golden era of the Laboratory had lasted almost four decades.

    Opis:
    The paper presents the results of sedimentological and biostratigraphical analyses from the Resko Przymorskie Lake spit (NW Poland), supported by radiocarbon datings. The study has aimed to recognize the geological structure of the spit and its base and to recognize the palaeoenivronmental changes. Nine sedimentary series composing the Resko Przymorskie Lake spit have been distinguished (I–IX). The oldest sediments are the Vistulian Glaciation till (series I) and fluvioglacial sand and gravel (series II). In the Early Holocene, in the study area there was a river valley (series III) followed by a shallow water basin (series IV), which was replaced by a peat bog (series V). In the Atlantic (7.4 ka cal BP), the water level rose (Littorina transgression) and accumulation of lagoonal sediments started (series VI). Biostratigraphic analysis of deposits in series VI indicates a marine influence. In the Atlantic and Subboreal, the spit moved southwards and fine sand (series VII) was deposited on lagoonal gyttja and silt (series VI). In the western part of the study area, peat accumulated (series VIII), dated at 6.7 ka cal BP (Late Atlantic). The youngest series IX is composed of aeolian fine sand in white dunes that formed in the last 400 years.

    Opis:
    The classical locality of Svinary in the eastern Bohemian Cretaceous Basin is the site of new biostratigraphic investigations. Besides some scarce macrofossil evidence, bulk sediment samples were processed to retrieve micropalaeontological assemblages, and calcareous nannofossil smear slides were analysed. The studied material provided calcareous nannofossil assemblages including Micula staurophora, Lithastrinus septenarius and Broinsonia parca expansa, thus documenting the Middle Coniacian (upper part of UC10 Zone and lower part of UC11 Zone). The foraminifera assemblage is relatively rich, planktonic species show a wide stratigraphical range, while the benthic association represented by Neoflabellina suturalis suturalis and Gaudryina carinata is very similar to the Coniacian biozone of Stensioeina granulata-Eponides whitei, valid for the Bohemian Cretaceous Basin. Ostracods are represented by two common cytherellid species, and two rare ornamented species: Imhotepia marssoni? and Pterygocythereis spinosa. Inoceramid bivalves, namely Platyceramus mantelli, and a newly recorded ammonite, Tridenticeras tridens, support the late Middle Coniacian age of the Svinary outcrop. New biostratigraphic results are given along with palaeoecological interpretations of newly collected fossil material.

    Opis:
    Two new species of ostracods of the family Progonocytheridae Sylvester-Bradley Camptocythere (C.) lateres Tesakova et Shurupova, sp. nov. and C. (C.) angustius Tesakova et Shurupova, sp. nov. from the Michalskii and Besnosovi ammonite zones (Upper Bajocian – Lower Bathonian, Middle Jurassic) of the Sokur section (Saratov) are described. The changes in ontogenesis in the phylogeny of Camptocythere (C.) lateres Tesakova et Shurupova in the stratigraphical interval corresponding to the Palaeocytheridea kalandadzei ostracod Zone, and especially to the beds with C. (C.) lateres, have been studied. The levels of the change in the predominant type of sculpture (corresponding to evolutionary boundaries) are recognized in the sculpture development among the adult representatives of the species in its phylogeny. This palaeobiogenetic (heterochrony) approach allows subdivision of the beds with C. (C.) lateres into three stratigrapical intervals characterized by changes in the type of sculpture.

    Do badań faunistycznych wykorzystano próbki osadów pobranych z otworu wiertniczego Sucha Wieś (Pojezierze Ełckie) z głębokości 153,60-178,00 m oraz z otworu wiertniczego Czarnucha (Równina Augustowska) z głębokości 96,05-118,85 m. Z badanej serii osadów jeziorno-bagiennych opisano szczątki różnych grup zwierząt: ślimaków (Gastropoda), małży (Bivalvia), małżoraczków (Ostrazoda), ryb (Pisces), chrząszczy (Coleoptera) i innych. Do określenia wieku osadów, szczególnie przydatne okazały się mięczaki (ślimaki i małże) oraz małżoraczki. Na podstawie obecności ślimaka Lithoglyphus jahni oraz małżoraczka Scottia browniana uznano, że osady nie mogą być młodsze od interglacjału mazowieckiego.
    Samples collected from the Sucha Wieś borehole (Ełk Lakeland) from a depth interval of 153.60-178.00 and from the Czarnucha borehole (Augustów Plain) from a depth interval of 96.05-118.85 m were analysed for faunal content. The lacustrine-marsh deposits contain fragments of various animals including gastropods, bivalves, ostracods, fish, Coleoptera and others. Especially important for age determinations are moluscs (gastropods and bivalves) and ostracods. The presence of Lithoglyphus jahni (gastropod) and Scottia browniana (ostracod) indicates that the deposits cannot be younger than the Mazovian Interglacial.

    Opis:
    The climate changes and related crucial environmental changes in the Late Glacial and Holocene in the Southern Baltic area can be investigated by mollusc and ostracod analyses. It is well known that accumulation of mineral and biogenic sediments in the Southern Baltic area began in the Late Glacial. The process took place in cold tundra lakes and mires. The presence of lake basins is confirmed by seismoacoustic investigations and the resulting 3D spatial model. Lacustrine sediments contain an assemblage of molluscs and ostracod fauna represented by freshwater species indicating cold climate, such as: Armiger crista f. cristatus, Gyraulus laevis, Lymnaea peregra, Pisidium casertanum, Pisidium casertanum f. ponderosa, Pisidium milium, Pisidium nitidum, Pisidium obtusale f. lapponicum, Valvata cristata, Pisidium conventus, Candona candida, Candona neglecta, Cytherissa lacustris, Darwinula stevensoni and Cypridopsis vidua. The accumulation in freshwater reservoirs was continued during the Early Holocene. Besides cold freshwater species, sediments of that age also contain freshwater species of molluscs and ostracods that required higher temperature: Bithynia tentaculata, Physa fontinalis, Pisidium amnicum, Candona compressa and Metacypris cordata. It indicates a climate warming in the Preboreal period. These lake sediments were partly destroyed and covered by marine sands during the Middle and Upper Holocene. Good indicators of changing from a freshwater to marine environment are the following marine species found in the sediments: Hydrobia ulvae, Hydrobia ventrosa, Cerastoderma glaucum, Mytilus edulis, Macoma balthica, Cyprideis torosa and Cytheromorpha fuscata.
