Upper Jurassic
Opis:: The Callovian and Upper Jurassic strata in the Nida Trough are similar to those from SW margin of Holy Cross Mountains, so the same lithostratigraphic pattern may be applied. Three facies zones are distinguished: NW, central and SE. Black deposits of the Middle Jurassic are covered by the Sandy Limestones and Marls (lower Callovian–Bukowskii Subz. Cordatum Z.). Locally, these strata are separated by the Calcareous Sandstones (uppermost Bathonian–lower Callovian). The Marly Limestones and Marls represent Bukowskii Subz. Cordatum Z.- Plicatilis Z. The Morawica Limestones represent Plicatilis Z.–Bimammatum Z. The Siedlce Limestones (facies: pelitic, pelitic-sponge, pelitic-coral) reach the Platynota Z. in central andNWpart and the top of Hypselocyclum Z. in a narrow zone in SE part of Nida Trough. The Chalky Limestones (facies: pelitic, biostromal) are equivalents of the uppermost Siedlce Limestones in the centre of the Nida Trough. Beyond this narrow zone in the SE part of the Nida Trough, the Lowermost Marly Horizon (Platynota Z.) and deposits of shallow water carbonate platform (Platynota Z.–Hypselocyclum Z.), Lower & Upper Oolites, Banded Limestones, Oolite-Platy Member, Platy Detrital Limestones, Platy Limestones and Underlying Shales are distinguished. The uppermost part of the incomplete section (Divisum Z. and Mutabilis Z.) is represented by the Skorków Lumachelles and Upper Platy Limestones in the entire Nida Trough while the Staniewice Lumachelles occur in its SE part. The knowledge of the Middle– Upper Jurassic deposits of the Nida Trough is important for palaeogeographical reconstructions of the whole Southern Poland, as the Nida Trough links other regions where the Jurassic deposits are well recognized in numerous outcrops and borehole sections.

Opis:: Chrom jest pierwiastkiem o szerokim zastosowaniu w przemyśle chemicznym i metalurgicznym, co stanowi główną przyczynę jego wprowadzania do środowiska w ściekach i wyciekach. Przykładem rejonu zanieczyszczonego związkami chromu są okolice Częstochowy. Szersze badania podjęto tu w latach 90. XX wieku z powodu zanieczyszczenia wód GZWP nr 326N, rozległego i zasobnego zbiornika szczelinowo-krasowego, występującego w utworach węglanowych jury górnej, stanowiącego główny poziom wodonośny oraz podstawę zaopatrzenia w wodę. Postawiono trzy koncepcje rozprzestrzeniania się zanieczyszczenia: (1) poziomy przepływ strumienia z dominacją procesów dyspersji, (2) głęboki poziomy przepływ strumienia z ascenzyjnym ruchem wód do współczesnego poziomu drenażu, (3) migracja zanieczyszczeń w wodach powierzchniowych. Wyniki opróbowania wód podziemnych przeprowadzonego w 2011 r. wykazały, że w porównaniu z 1995 r. zanieczyszczenie chromem uległo zmniejszeniu, jednak problem w dalszym ciągu istnieje, a kierunki i drogi migracji zanieczyszczeń w wodach poziomu górnojurajskiego nadal nie zostały jednoznacznie rozpoznane.
Chromium is an element widely used in chemical and metallurgical industries that is the primary source of release of chromium compounds into the environment with industrial wastewater. An example of the region contaminated by chromium compounds is Częstochowa area. Wider research was undertaken in‘90s due to water pollution in the spacious and affluent fracture-karst reservoir MGWB No. 326N, associated with the Upper Jurassic carbonate formations. This MGWB is the main aquifer and a source of water for Częstochowa. The three hypotheses of chromium pollution pathways were formulated: (1) horizontal water flow with domination of dispersion processes, (2) deep horizontal flow with ascending movement of water to the contemporary drainage level, (3) migration of pollutants in surface water. Sampling of groundwater conducted in 2011 showed that compared to 1995, chromium pollution was reduced, although up to now the problem still exists and the directions and pathways of migration of contaminated Upper Jurassic groundwater have not been yet univocally identified.

Opis:: This paper highlights the application of shallow non-invasive geophysics (electrical resistivity tomography) supported by sedimentological analysis applied to the investigation, description and interpretation of Upper Jurassic limestones exposed in the abandoned quarry near the village of Tomaszowice (Kraków Upland, southern Poland). Within this site, on the northern margin of the Krzeszowice Graben, a facies diversity of Upper Jurassic limestones can be observed. Field exposures were analysed to broadly characterize these Upper Jurassic limestones in terms of facies and microfacies development. Three facies types, including pelitic limestones, bedded limestones and carbonate gravity-flow deposits, composed of numerous microfacies, have been distinguished. ERT study using a dipole-dipole array has been carried out, along 5 parallel 110 m long profiles and along a perpendicular 110 m long profile, north of the Tomaszowice Quarry wall. The use of ERT in combination with the geological data allowed characterization and description of the geology at the research site as well as the determination of the lithological composition and internal architecture of the subsurface. Furthermore, the ERT interpretation results indicated the presence of a series of a secondary faults closely linked with the Krzeszowice Graben. The distribution of the gravity-flow deposits reflects the fault zone pattern of the graben and Late Jurassic fault activity.

Opis:: Oxygen and carbon isotope ratios of well-preserved calcitic bivalves from the Lower-lowermost Upper Kimmeridgian of Central Poland (SW margin of the Holy Cross Mountains) have been studied to reconstruct palaeoenvironmental conditions and variations in ancient water chemistry. Low and scattered δ18O and δ13C values of bivalve shells from shallow carbonate deposits of the Hypselocyclum and the Hypselocyclum-Divisum zone boundary (-3.5 to -1.5, and 2.6 to 4.0‰, respectively) are a result of salinity changes, and local variations in the composition of dissolved inorganic carbon (DIC) in conditions of restricted water circulation. A slight increase in bivalve δ13C values and more densely clustering of δ18O values is observed after the marine transgression at the Divisum-Mutabilis zone boundary. A global decrease of δ13C values of marine carbonates is partly recorded in Lower-lowermost Upper Kimmeridgian bulk carbonates from central Poland (from the Radomsko Elevation and the Wieluń Upland). Local negative shifts and the data scatter are, however, observed in rocks deposited in a very shallow environment of carbonate platforms during the Platynota and Hypselocyclum chrons. This interval corresponds to the uppermost part of the lowstand systems track of a major regressive trend, which had started already in the Late Oxfordian.

Opis:: The stratigraphical interval of the Kimmeridgian between the Bimammatum and the Hypselocylum zones in the SW margin of the Holy Cross Mts. shows a transition from the open shelf deep-neritic sponge megafacies to the shallow-water carbonate platform, including its development and decline. The uniform progradation of the shallow-water carbonate platform occurred at the end of the Planula Chron. Development of the shallow-water carbonate platform was controlled by climatic and tectonic factors. The former induced by orbital cyclicity resulted in changes of sea-level, revealed i.a. by the incoming of open-marine ammonite faunas, the latter were related to the synsedimentary activity of faults which resulted in contrasted facies changes. The episodically occurring strong influx of siliciclastic material was at least partly controlled by the tectonic activity. The newly elaborated formal lithostratigraphic subdivision takes into account the facies development of the succession in relation to climatically and tectonically induced changes. Such is e.g. the Małogoszcz Oolite Formation, corresponding to a single 100-kyr eccentricity cycle from the late Platynota Chron to the earliest Hypselocyclum Chron, bordered from the base and top by two transgressive climatically-controlled levels. The final stage of the shallow-water platform development at the end of the Hypselocyclum Chron was marked by the successive limitation of restricted environments, and the appearance of more open-marine conditions related to tectonic subsidence of the area of study. Comparison between the carbonate platform development of the Holy Cross Mts. in central Poland, and the coeval shallow-water carbonates of the Jura Mts. in northern Switzerland and south-eastern France provides an opportunity to consider similarities in the successions which can be attributed to the climatically-controlled sedimentary cyclicity and/or the wide-ranged tectonic phenomena. The palaeontological part of the study gives comments on the classification and phylogeny of ammonites of the families Ataxioceratidae and Aulacostephanidae.

Opis:: The ammonite succession in the stratigraphical interval from the Bifurcatus Zone, through the Hypselum Zone, up to the lower part of the Bimammatum Zone corresponding to a large part of the Submediterranean Upper Oxfordian is studied in several sections of the Polish Jura in central Poland. The sections have yielded numerous ammonites of Submediterranean–Mediterranean affinity, but also, some of Boreal and Subboreal character. The co-occurrence of ammonites of different bioprovinces makes possible the correlation between the different zonal schemes – especially between the Subboreal/Boreal zonations and the Submediterranean/Mediterranean zonation. The correlation shows that the boundary of the Pseudocordata and Baylei zones (Subboreal) and its equivalent – the boundary of the Rosenkrantzi and Bauhini zones (Boreal), currently proposed as the primary standard of the Oxfordian-Kimmeridgian boundary within its GSSP at Staffin Bay (Isle of Skye, Scotland), runs in the Submediterranean/Mediterranean Upper Oxfordian near the base of the Bimammatum Zone. This discovery removes the main obstacle against the formal recognition of the Staffin Bay section as representing the uniform base of the Kimmeridgian Stage in the World and its GSSP. The ammonite taxa recognized are commented on and/or described, and suggestions on their taxonomical and phylogenetical relations are given in the palaeontological part of the study. A new taxon is established: Microbiplices anglicus vieluniensis subsp. nov.

Opis:: Middle to Upper Jurassic of the Zamkowa Mt (Trzy Korony massif) in the Pieniny Klippen Belt show special development of the Czertezik Succession. The section reveals very thick units of crinoidal limestones: the Smolegowa Limestone Formation grainstones abruptly laterally replaced by crinoidal-spiculitic grainstones of the Flaki Limestone Formation; these are overlain by strongly condensed pelagic limestones - in their uppermost part rich in planktonic foraminifers and radiolarians - with abundant detrital grains of quartz and dolomite, fragments of crinoidal limestones, and the glauconitic nodules (glaucony). Both the development of attaining large thicknesses of strongly facies contrasted crinoidal units supplied from overhanging "crinoid gardens", as well as the appearance of abundant grains in younger pelagic limestones, prove the synsedimentary faulting which produced an active tectonic scarp during the Bajocian and at the turn of Callovian and Oxfordian.

Opis:: New data are presented in relation to the worldwide definition of the Oxfordian/Kimmeridgian boundary, i.e. the base of the Kimmeridgian Stage. This data, mostly acquired in the past decade, supports the 2006 proposal to make the uniform boundary of the stages in the Flodigarry section at Staffin Bay on the Isle of Skye, northern Scotland. This boundary is based on the Subboreal-Boreal ammonite successions, and it is distinguished by the Pictonia flodigarriensis horizon at the base of the Subboreal Baylei Zone, and which corresponds precisely to the base of the Boreal Bauhini Zone. The boundary lies in the 0.16 m interval (1.24–1.08 m) below bed 36 in sections F6 at Flodigarry and it is thus proposed as the GSSP for the Oxfordian/ Kimmeridgian boundary. This boundary is recognized also by other stratigraphical data – palaeontological, geochemical and palaeomagnetic (including its well documented position close to the boundary between magnetozones F3n, and F3r which is placed in the 0.20 m interval – 1.28 m to 1.48 m below bed 36 – the latter corresponding to marine magnetic anomaly M26r). The boundary is clearly recognizable also in other sections of the Subboreal and Boreal areas discussed in the study, including southern England, Pomerania and the Peri-Baltic Syneclise, Russian Platform, Northern Central Siberia, Franz-Josef Land, Barents Sea and Norwegian Sea. It can be recognized also in the Submediterranean-Mediterranean areas of Europe and Asia where it correlates with the boundary between the Hypselum and the Bimmamatum ammonite zones. The changes in ammonite faunas at the boundary of these ammonite zones – mostly of ammonites of the families Aspidoceratidae and Oppeliidae – also enables the recognition of the boundary in the Tethyan and Indo-Pacific areas – such as the central part of the Americas (Cuba, Mexico), southern America, and southern parts of Asia. The climatic and environmental changes near to the Oxfordian/Kimmeridgian boundary discussed in the study relate mostly to the European areas. They show that very unstable environments at the end of the Oxfordian were subsequently replaced by more stable conditions representing a generally warming trend during the earliest Kimmeridgian. The definition of the boundary between the Oxfordian and Kimmeridgian as given in this study results in its wide correlation potential and means that it can be recognized in the different marine successions of the World.

Pangerpeton sinensis gen. et sp. nov. is represented by a nearly complete skeletal impression of a postmetamorphosed salamander from the Late Jurassic/Early Cretaceous locality of Wubaiding, Liaoning Province. It is characterised by a short wide skull and only 14 presacral vertebrae. Associated soft tissue impressions suggest a warty skin and a broad body outline. Phylogenetic analysis indicates a basal position within Caudata, either just within or just outside crown−group Urodela.

Opis:: The precise record of simoceratins sampled bed−by−bed is first reported from Mexico (Mazatepec area in Puebla, central−eastern Mexico), as well as the existence of lappeted peristomes in these ammonites. Both Pseudovolanoceras aesinense and the subspecies Pseudovolanoceras aesinense chignahuapense are shown to occur among Mexican simoceratins. The European species and the Mexican subspecies share the same stratigraphic range in the studied sections, yet they differ in ephebic sculpture. Ecological adaptation to neritic seas corresponding to eastern Mexico areas is interpreted, forcing phenotypic deviation with geographic significance, i.e., subspeciation. The new subspecies would indicate stratigraphic horizons within the Semiformiceras semiforme/Haploceras verruciferum Chronozone in the Mediterranean Tethys. A revision of contemporaneous simoceratins in the Americas is founded on a comparative analysis with respect to the European species P. aesinense.

Opis:: The Upper Jurassic limestones in the vicinity of Cracow underwent extensive dedolomitization process. Petrographic and cathodoluminescent analyses of carbonates in four test areas confirm the dedolomitization as have been developed with various intensity. The alteration of dolomite into calcite occurs as centripetal and centrifugal dedolomitization. Both processes lead finally to a complete disintegration of the dolomite crystals; calcite pseudomorphs after dolorhombs are the end products. These calcite pseudomorphs are abundant in limestones of St. Anna Mt. and in the Kostrze quarry, but are scarce in the Twardowski Cliffs area and in the outcrop of Księża Mt., which indicates a less advanced and slower dedolomitization process in the latter two areas. Most probably the initiation of dedolomitization started from the moment when a carbonate bank emerged from the sea water (Vierek, 2003); temperature of mixing fluids decreased considerably, whereas Ca 2+/Mg+- ratio in the same fluids increased.

Opis:: Rare-earth elements (REE) were determined for the Upper Jurassic limestone and dolomites from the following outcrops: Góra OEw. Anny, Kostrze Quarry, Księża Góra, and Skały Twardowskiego. REE patterns are similar for all the investigated samples. Dolomites and limestone are enriched in light REE, they exhibit positive La anomalies, and negative Ce and Eu anomalies. Negative Ce and Eu anomalies are typical for oxidizing environments during dolomitization processes. Distinct enrichment in light REE comparing to heavy REE indi-cates that the sea water was not the only component of dolomitization fluids.

Opis:: Vertebrate remains, mostly cryptodiran turtle shellfragments, pliosaur skull bones and teeth, plesiosaur vertebrae and crocodylomorph isolated teeth and skull fragments are described from the Upper Jurassic (Kimmeridgian) limestone beds of Krzyżanowice in the NE margin of the Holy Cross Mountains in Poland. The vertebrate fossils were collected during the palaeontological excavations conducted in 2018 and 2019 by the authors, and in the 1960s by a scientific team from the Museum of the Earth and the Institute of Paleobiology Polish Academy of Sciences. All osteological remains are generally very well preserved. This interesting vertebrate bones association from the upper part of the Kimmeridgian represents fossils of animals from two different types of environment. The first contains costal reptiles, like turtles and crocodylomorphs, the second one contains large pelagic animals - pliosaurids and plesiosaurids. This new vertebrate fauna from Poland has been correlated with age-equivalents from other regions of Europe and both Boreal/Subboreal and Mediterranean palaeobiogeographical realms.

Opis:: The Owadów-Brzezinki quarry is one of the most important paleontological sites in Poland, known from its exceptionally well-preserved Late Jurassic (Tithonian) fossils of marine and terrestrial biota, including horseshoe crabs and decapod crustaceans, rare ammonites, various insects and pterosaurs. This paper describes the discovery of new, well preserved reptile bones (ichthyosaurs, turtles and crocodylomorphs), which adds sigmficantly to our knowledge of these three gr°upü. The occurrence of large marine reptiles show open marine connections with the Sub- boreal-Boreal areas (both with Subboreal English seas and Boreal Arctic areas), and the Submediterranean Province (corresponding to the area of southern Germany).

Opis:: An isolated posterior cervical vertebra of a sauropod discovered at Phu Dan Ma (Kalasin Province, northeastern Thailand) is the first informative postcranial specimen from the Phu Kradung Formation, a Upper Jurassic to Lower Cretaceous continental unit. The vertebra is referred to the family Mamenchisauridae, otherwise mainly known from China. In addition, spatulate teeth from the same formation and a mid−dorsal vertebra from the Upper Jurassic Khlong Min Formation of southern Thailand are reassigned to this family. The occurrence of mamenchisaurids in the earliest Cretaceous of Thailand supports a hypothesis of geographical isolation of Central, Eastern, and Southeast Asia during the Late Jurassic. It also suggests that the main changes in their dinosaur assemblages occurred during the Early Cretaceous, rather than at the Jurassic–Cretaceous boundary.
