Opis:
The giant, up to 40 cm high littorinoid gastropods from the Middle Tithonian to Berriasian carbonates of the Alpine-Carpathian northern Tethys margin are assigned to the genus Leviathania. The genus is distributed from Spain to the Caucasus. Some species formed dense populations in the wide-spread, highly productive lagoonal environments situated on the carbonate platforms of Ernstbrunn (Austria), Mikulov, Štramberk (both Czech Republic), and Nyzhniv (Ukraine). The conspicuous morphology, comprising very large shells with strongly angulated whorls and especially the phaneromphalous umbilicus exclude the traditional attributions of this genus to the families Purpurinidae and Purpuroideidae. Therefore, we establish the new family Leviathaniidae for the type genus Leviathania. The family comprises the largest pre-Cenozoic gastropods, represented by a yet unnamed gigantic Leviathania species from the latest Tithonian or early Berriasian of Ukraine. The gastropods are tentatively assumed to have fed omnivorous, i.e., on a mixed detrital-algal diet, based on comparable population densities as the large modern queen conch Lobatusgigas from the Caribbean Sea.

Opis:
The Late Jurassic aspidoceratoid genus Pseudhimalayites Spath is scarcely recorded but widely distributed in the Andean basins, the Caribbean region, and in the European Tethys. From Ponti Zone (Lower Tithonian) rocks of the Betic Range in Carchelejo we describe here the new species Pseudhimalayites carchelejensis, based on a macroconch (female) holotype. The corresponding microconch (male), described from the same ammonite assemblage, would belong to the morphogenus Simocosmoceras Spath which groups the microconchs of Pseudhimalayites. P. carchelejensis n. sp. differs from the coeval Pseudhimalayites steinmanni (Haupt) by lacking ventral tubercles in the phragmocone and by bearing umbilical tubercles only from the adult whorl of the phragmocone. These differences illustrate a significant morphologic divergence between the Andean and the Tethyan lineages.

Opis:
The ammonite fauna of the Tithonian–Berriasian of the Vaca Muerta Formation in Pampa Tril has been recently described in detail. New important specimens and additional information are presented in this paper. The phyletic evolution of Choicensisphinctes, passing from C. platyconus to C. erinoides is confirmed, as well as the sexual dimorphic correspondence of this latter with C. mendozanus. A microconch of the genus Krantziceras is described for the first time. New specimens of Substeueroceras koeneni identical to the paralec¬totype, along with material already described from the koeneni Hz. (Koeneni Zone), point to the fixation of this horizon as the type horizon of the species. New specimens of Subthurmannia boissieri from the Damesi Zone match clearly the range of variation of this species in Spain, thus providing an element for time-correlation with the Tethyan standard scale. Additional material from the internispinosum alpha Hz. confirms the origin of W. internispinosum from C. proximus by the inception of an evolutionary innovation in the juvenile ontogeny.

Opis:
The ammonite biostratigraphy as well as the organic matter content, its type and maturity of the Pałuki Formation, belonging to the fine, siliciclastic Kimmeridge Clay type facies, were investigated in five deep boreholes from the central-eastern part of the Łódź Synclinorium in Central Poland. The studied deposits are assigned to the Eudoxus and Autissiodorensis zones of the Upper Kimmeridgian as well as the Klimovi, Sokolovi, Pseudoscythica and Puschi (=Tenuicostata) zones of the Lower Tithonian (“Lower Volgian”). The Pałuki Formation shows in its lower and middle parts average TOC concentrations of ca. 2.5 wt.% and prominent, restricted increases in organic matter content, which are found in the mid-Eudoxus Zone, the lowermost part of the Autisiodorensis Zone, and at the Sokolovi–Pseudoscythica zone boundary. These stratigraphical intervals correlate well with rich in organic matter levels present in the Kimmeridge Clay Formation of NW Europe. The periodic expansions of Submediterranean and Subboreal-Boreal ammonites corresponded mostly to the transgressive phases, often correlated with a higher content of organic matter. The development of special morphologies of ammonites, such as the small-sized, nectopelagic forms of Nannocardioceras in the Late Kimmeridgian, has also been related to the deposition of shales rich in organic matter during the transgression maxima. The organic matter present in the Pałuki Formation mostly consists of Type II kerogen and is immature or early mature with respect to hydrocarbon generation, which is in agreement with previously published data. Evaluation of the new and published geochemical, lithological and structural data from the Pałuki Formation in the central-eastern part of the Łódź Synclinorium shows that these deposits could not have been a considerable source of crude oil or gas.

Opis:
The Tithonian ammonite succession at the Owadów–Brzezinki quarry, central Poland shows the presence of Subboreal ammonites of both NE European (“Volgian”) and NW European (“Bolonian–Portlandian”) affinity, making possible the correlation between the relevant ammonite subdivisions. The former are represented by Zaraiskites – Z. regularis Kutek and Z. zarajskensis (Michalski) as well as an early form of Virgatites – V. gerassimovi Mitta which enable the recognition of the upper part of the Scythicus Zone (the Zaraj¬skensis Subzone) and the lower part of the Virgatus Zone (the Gerassimovi Subzone) of the “Middle Volgian”. The latter are represented by Virgatopavlovia, which enables the correlation with the Fittoni Zone of the uppermost “Bolonian”, and by still younger assemblage of small-sized virgatitids – such as V. pusillus (Michalski), showing similarity to Progalbanites albani (Arkell) of the Albani Zone of the lowermost “Portlandian”. The new species established include: Zaraiskites lewinskii sp. nov. which represents a new member of the virgatitid lineage linking an older Z. pommerania (Arkell) with younger small-sized Virgatites, as well as two species of the genus Virgatopavlovia – V. janeki sp. nov. and V. dembowskae sp. nov. The appearance of ammonites of NW and NE European affinity in central Poland resulted from the opening of the new sea routes possibly related with tectonic activity in northern European areas at the transition from Early to Late Tithonian.

Opis:
The radiolarian and calpionellid microfacies are characteristic for the latest Tithonian–Early Berriasian limestones of the Guasasa Formation in the Sierra del Infierno, western Cuba. The limestones of the uppermost part of the El Americano Memberbelongto the Late Tithonian Crassicollaria intermedia Subzone, Crassicollaria Standard Zone, and to the basal part of the Early Berriasian Calpionella alpina Subzone. The lower part of the Tumbadero Member is assigned to the C. alpina Subzone of the Calpionella Standard Zone. A heteromorph ammonite assemblage (Protancyloceras-Vinalesites) crosses the Crassicollaria/Calpionella Zones boundary. The studied limestones belong to three nannoconid assemblages of latest Tithonian–Early Berriasian age assigned to Nannoconus wintereri Subzone, N. steinmannii minor Subzone and N. steinmannii steinmannii Zone. Radiolarian taxa identified in thin sections are consistent with the lower part of D2 radiolarian zone from Western Tethys. The investigated deposits have been probably accumulated in the dysaerobic zone. At the Tithonian–Berriasian (J/K) boundary, dysaerobic to anaerobic conditions could be widespread in the deeper waters of the northwestern Proto-Caribbean basin.
W niniejszej pracy zostały zbadane dwa profile obejmujące wapienie najwyższego tytonu i dolnego beriasu w Sierra del Infierno, na zachód od Vifiales w zachodniej części Kuby (Fig. 1A-C). Wapienie najwyższej części ogniwa El Americano formacji Guasasa (Tab. 1) należą do podpoziomu Crassicollaria intermedia poziomu standardowego Crassicollaria (górny tyton) i najniższej części podpoziomu Calpionella alpina (dolny berias) poziomu standardowego Calpionella (Fig. 2, 3). Dolna część ogniwa Tumbadero została zaliczona do podpoziomu C. alpina. W wapieniach najwyższej części ogniwa El Americano (Fig. 4A) i dolnej części ogniwa Tumbadero (Fig. 4B) charakterystyczne są mikrofacje kalpionellidowa (Fig. 5A) i radiolariowa (Fig. 6A). Pelmikrosparyty (Fig. 5B) i laminowane biomikryty (Fig. 6B) również są spotykane w dolnym beriasie. Kalpionellidy (Fig. 7A-I) są reprezentowane przez pojedyncze okazy do bardzo licznych zespołów (Tab. 2); zwykle są one słabo zachowane. Jest to już wcześniej opisana cecha kalpionellidów obecnych w wapieniach późnego tytonu i beriasu sukcesji Sierra de los Organos (Pop, 1976). Badane wapienie zawierają również nannokonidy (Fig. 8, 9A-H) zaliczone tutaj do podpoziomów Nannoconus wintereri i N. steinmannii minor oraz do poziomu N. steinmannii steinmannii (Tab. 3). Granica ogniw El Americano i Tumbadero znajduje się w obrębie podpoziomu N. steinmannii minor. Radiolarie oznaczone w płytkach cienkich (Fig. 10A-J, 11) odpowiadają dolnej części poziomu radio-lariowego D2 ustalonego w formacji Maiolica zachodniej Tetydy (Jud, 1994). Niektóre rodzaje (Ristola, Mirifusus) są często spotykane w badanych profilach. Obecność juwenilnych amonitów rozwiniętych: Protancyloceras gr. hondense (Imlay) (Fig. 12A), Protancyloceras sp. i Vinalesites sp. (Fig. 12B) została stwierdzona w niektórych płytkach cienkich wykonanych z wapieni (Tab. 4). Zespół tych amonitów przekracza granicę poziomów kalpionellidowych Crassicollaria i Calpionella (Tab. 5). Szare, ciemnoszare i czarne wapienie najwyższej części ogniwa El Americano i dolnej części ogniwa Tumbadero zostały osadzone prawdopodobnie w strefie dysaerobowej, w której fauna bentosowa była bardzo nieliczna (Fig. 12C). Ławice wapieni zazwyczaj nie zawierają struktur wskazujących na intensywną działalność organizmów ryjących w osadzie. W pobliżu granicy tytonu i beriasu (J/K), warunki dysaerobowe (lub nawet anaerobowe) mogły być rozprzestrzenione w głębszych wodach północno-zachodniej części basenu Protokaraibskiego. Takie warunki wskazująna raczej słabą cyrkulację w głębszych wodach tego dosyć wąskiego w tym czasie basenu.

Opis:
The studied corals have been collected from cores of boreholes located in the central part of the Polish Carpathian Foreland in the Dąbrowa Tarnowska–Szczucin area. The Jurassic complex in this area presents a continuous stratigraphic section from the Upper Callovian to Tithonian, locally passing to the Lower Cretaceous (Berriasian). Its thickness exceeds 1,100 m in this area. This complex is composed of marine, mainly shallow-water deposits. The corals occur within the upper part of the Upper Jurassic (Tithonian) deposits, almost entirely within the Swarzów Limestone Formation (= coral-algal limestone formation). This occurrence marks the northernmost extent of Tithonian shallow-water corals in Poland and one of the northernmost in Europe. 42 coral species (among them 14 in open nomenclature) were identified in deposits of this formation. They include two new species: Complexastrea magna and Complexastrea dabroviensis. All taxa, except one, belong to the order Scleractinia. The described assemblage displays a Late Jurassic character. The broader stratigraphic span is assigned to some species, which are quoted from the Middle Jurassic and some species lasted until the Early Cretaceous, Berriasian and/or Valanginian.

The finding of two new specimens and a reappraisal of the single original specimen of the problematic giant Canadian Late Ju- rassic ammonite Titanites occidentalis Frebold results in the creation of Corbinites, n. gen. It is assigned to the ataxioceratid subfamily Lithacoceratinae largely because of the presence of variocostate and previously unrecognized ataxioceratoid ribbing in middle and late growth stages. With enigmatic ancestry and geographically removed other forms with similar characteristics, the species may have been endemic in the relatively isolated early Alberta foreland basin of western interior Canada.

Opis:
The Late Jurassic shallow-water carbonates with intervening clayey-marly deeper-water deposits in the Holy Cross Mts. area formed over large bank of the elevated part of the Northern Tethyan Shelf during about 12 myr. They comprise three main successions (I, II and III) deposited partly in different environmental conditions, controlled by tectonic and climatic factors, and still preserved in the  north-eastern margin, the north-western margin and the south-western margin of the Holy Cross Mountains. The history of sedimentation is presented according to the concept of the large tectono-stratigraphic units COK, LUK and KVB, which owe their origin to variable rates of tectonic subsidence, as introduced by Kutek (1994) for the area of central Poland. The studied deposits of the COK megasequence cor- responding to the Upper Oxfordian and the Lower Kimmeridgian up to the Hypselocyclum Zone consist of coral limestones, various grained (including oolitic) limestones, and micritic limestones formed over the gradually enlarging shallow-water carbonate platform of the Holy Cross Mts. This platform was subsequently subdivided into two elevated areas, separated by a depressed zone in the middle, bounded by the Nowe Miasto–Iłża–Bałtów Fault Zone in the north-east and the Holy Cross Fault System in the south. The younger mega- sequence LUK with it strongly transgressive character marks the successive stages of the marine transgression which entered the central, lowered part of the area of the Holy Cross Mts. from the west, where it appeared already in the early Hypselocyclum Chron. It succes- sively spread across the Holy Cross Mts. area towards the north-east and south bringing everywhere the deposition of various oyster lu- machelles and marls with ammonites at the end of the Hypselocyclum Chron and during the Divisum Chron of the Early Kimmeridgian to the Acanthicum/Mutabilis Chron of the earliest Late Kimmeridgian. The following megasequence KVB is represented by the detrital lu- machelles and chalky limestones with nereineids of the Eudoxus Chron of the Late Kimmeridgian marking the development of still younger shallow-water carbonate platform in the uplifted areas in the north-eastern and possibly the south-western margins of the moun- tains, allegedly subdivided by a deeper area of sedimentation of marly deposits. The youngest Late Jurassic deposits of the Holy Cross Mts., are very fragmentarily preserved, mostly because of Early Cretaceous uplift and erosion. They suggest an initial episode of complete drowning of the carbonate platform which became covered by marly deposits during the Early Tithonian, and the subsequent restoration of shallow-water carbonate sedimentation at the end of the Early Tithonian.

Opis:
Loose elements of the roveacrinid Saccocoma from the Tithonian red Rogoża Coquina, Rogoźnik, Pieniny Klippen Belt, Poland, are used to test the contradictory opinions on the mode of life of Saccocoma. The investigated elements belong to three morphological groups, which represent at least two separate species: S. tenella, S. vernioryi, and a third form, whose brachials resemble those of S. vernioryi but are equipped with wings of different shape. The geometry of brachials’ articular surfaces reveals that the arms of Saccocoma were relatively inflexible in their proximal part and left the cup at an angle of no more than 45, then spread gradually to the sides. There is no evidence that the wings were permanently oriented in either horizontal or vertical position, as proposed by two different benthic life−style hypotheses. The first secundibrachial was probably more similar to the first primibrachial than to the third secundibrachial, in contrast to the traditional assumption. The winged parts of the arms were too close to the cup and presumably too stiff to propel the animal in the water efficiently. Swimming was probably achieved by movements of the distal, finely branched parts of the arms. The nonhorizontal attitude of the winged parts of the arms is also not entirely consistent with the assumption that they functioned as a parachute. Moreover, the wings added some weight and thus increased the energy costs associated with swimming. The hydrodynamic benefits balancing these extra costs are not entirely clear, but it seems probable that the wings reduced the sinking rate of the animal not by increasing the pressure drag, as suggested by the parachute−analogy, but by increasing the surface drag (friction drag), which also harmonize with the presence of spines, reticulate sculpture and conspicuous vacuolar ornamentation in some species of Saccocoma.

Być może, do tytonu należy prawie cała formacja ze Swarzowa i najniższa część leżącej wyżej formacji wapienno-dolomitycznej, muszlowcowej ze Smęgorzowa. Wyższa część formacji ze Smęgorzowa może należeć już do kredy dolnej, do beriasu.
The Upper Jurassic coral-algal Swarzów Formation in the Dąbrowa Tarnowska–Szczucin area, occuring in the middle part of the Carpathian Foreland Poland contains rich macrofossils (i.e. scleractinian corals, bryozoans, brachiopods, algae) and generally sparse assemblages of microfossils. Some of the latter are interesting as a biostratigraphical tool. Thus, the presence of rare calpionellids (Calpionella alpina, C. aff. alpina, Crassicolaria cf. brevis, Tintinopsella cf. carpatica) argues for Late Tithonian age (standard Crassicollaria zone) of the upper part of this formation. It is suggested that the Swarzów Limestone Formation almost entirely represents the Tithonian, which probably reaches the lowest part of the lithostratigraphic unit of the Smęgorzów Limestone-Dolomitic Coquina Formation. The upper part of this unit may belong to the Lower Cretaceous, to Berriasian.

Opis:
Detailed magnetostratigraphic investigations of the Tithonian–Berriasian strata, integrated with litho- and biostratigraphic observations were carried out within the Bobrowiec Unit of the Lower Sub-Tatric (Krina) Nappe in theWestern Tatra Mts. Amodification of the existing lithostratigraphic scheme is proposed, splitting the Pieniny Limestone Formation (sensu Lefeld et al. 1985) into two formations, accordingly with lithostratigraphic subdivisions of the coeval deposits in some other parts of the Krina Nappe in Slovakia: the Jasenina Formation (includes Pośrednie Member sensu Pszczółkowski 1996, in its uppermost part) and the Osnica Formation (Osnica Member sensu Pszczółkowski 1996). The Jurassic/Cretaceous boundary, as defined by calpionellids, falls within the lowermost part of the Osnica Fm. Magnetozones from CM20r (Lower/Upper Tithonian boundary) up to CM16n (Upper Berriasian) were identified. Jurassic/Cretaceous boundary is situated within the CM19n magnetozone, below the short reversed Brodno subzone. Magnetostratigraphic correlation of four sections revealed existence of some “gaps” which are interpreted as tectonic reductions, which have to be considered while calculating the sedimentation rate which, however, might be roughly estimated. Sedimentation was relatively slow within the Jasenina Formation (5–7 m/My), but accelerated within the Osnica Fm (mean value: 10–15 m/My) and in the investigated lower part of the Kościeliska Marl Fm (20–30 m/My). Presence of hematite correlates with low sedimentation rate.

Opis:
Numerous fully cored boreholes completed in the last years in central Poland (Kleszczów Graben area, southern border of the Łódź Depression) enabled the researchers to obtain new sedimentological data on the Oxfordian-Tithonian continuous sedimentary record in the Polish part of the northern Tethys shelf. Twenty-two facies were distinguished in the sedimentological succession. The facies represent the outer-, mid- and inner-ramp environments, including evaporitic episodes and palaeosols. The facies document that the Oxfordian-Lower Kimmeridgian (up to Hypselocyclum) carbonate ramp has evolved to the Upper Kimmeridgian-Tithonian carbonate-siliciclastic ramp. Among the Kimmeridgian deposits, numerous hardgrounds, tidal channel deposits and gravity flow sediments were identified. The Kleszczów Graben sedimentary succession is discussed along with the lithostratigraphical units known from the adjacent regions of southern and central Poland.
