abstract = {The middle and upper parts of the Skały Fm, Early to Middle Givetian in age, were investigated in four sections at Miłoszów Wood in the Łysogóry Region (northern region of the Holy Cross Mountains; central Poland). The dating is based on conodonts (Polygnathus timorensis Zone to the later part of the Polygnathus varcus/Polygnathus rhenanus Zone; early Polygnathus ansatus Zone cannot be excluded) and spores (Ex1–2 subzones) and, coupled with cartographic analysis and geophysical investigation, allows correlation within the strongly faulted succession. Significant lateral facies variations within the carbonate ramp depositional system in comparison with the better studied Grzegorzowice–Skały section, about 3 km distant, are documented, thanks to conodont-based correlation of both successions. Foraminifers, fungi, sponges, rugose and tabulate corals, medu-sozoans, microconchids and cornulitids, polychaetes (scolecodonts), molluscs (bivalves; rostroconchs; and gas-tropods), arthropods (trilobites and ostracods), bryozoans, hederelloids, ascodictyids, brachiopods, echinoderms (mostly crinoids; rare echinoids; holuthurians; and ophiocistoids), conodonts, fish, plants (prasinophytes; chloro-phycophytes; and land plant spores), and acritarchs are present. Brachiopods are the most diverse phylum present (68 species), other richly represented groups are bryozoans and echinoderms; in contrast, cephalopods and trilobites are low in diversity and abundance. The muddy, middle to outer ramp biota (200 marine taxa; including 170 species of marine animals; 22 photoautotrophs; 6 forams) represents a mixture of allochthonous shallower-wa-ter communities (upper BA3), including storm-and possibly tsunami-affected coral mounds, and autochthonous deep-water soft-bottom brachiopod (e.g.; Bifida–Echinocoelia) communities (BA 4–5). The richness and diversity of the Miłoszów biota is relatively high, comparable with other approximately coeval pre-Taghanic ecosystems during the Devonian climatic deterioration (cooling). Preliminary data indicate that in the Holy Cross Mountains, no large-scale replacement of brachiopod (and probably many other benthic ones; like crinoids) communities took place between the Early–Middle Givetian and the Early Frasnian, in contrast to the demise of the Hamilton/ Upper Tully fauna in the Appalachian Basin. Such a similarity of pre-and post-Taghanic faunas does not exclude the occurrence of environmental perturbations and transient community turnovers, caused by immigrations during the Taghanic Biocrisis, but evidences the successful recovery of the indigenous biota. © 2022, Polish Geological Society.

abstract = {The Toregua Formation in northern Bolivia comprises a continuous succession of sedimentary rocks containing two glacial intervals related to the onset of the Late Paleozoic Ice Age (LPIA). The provenance and depositional tectonic setting of the Upper Devonian–Mississippian (lower) and Pennsylvanian (upper) glacial intervals are separated by non-glacial deposits observed in the Manuripi X-1 and Pando X-1 drill cores, from which petrography, geochemistry, detrital zircon U–Pb and monazite Th–U-total Pb dating are described. Zircon age spectra of sandstone clasts and diamictite indicate an upward change in provenance. Zircon age data from the lower glacial interval yielded age groups at 700–500 Ma, 1300–900 Ma and 2200–1820 Ma, while the monazite gave ages in the range of 600-500 Ma. These age populations correspond to the Guaporé Shield and/or the Arequipa Massif. Detrital zircon from the upper glacial interval has a significant age population at 330–300 Ma that reflects prominent input from the Eastern Cordillera. The maximum depositional age of the upper glacial interval was constrained to ca. 308 Ma. Provenance discrimination diagrams, based on major element geochemistry and trace element ratios, suggest that the glacial and non-glacial sediments were mainly sourced from felsic source rocks. The moderate to high chemical index of alteration (CIA <81) and mineralogical index of alteration (MIA = 81–90 values), abundance of siderite clasts and dominance of kaolinite and abraded zircon grains (without correlation between age and zircon roundness) indicate that the lower glacier incorporated material from older sedimentary covers. In the upper glacial interval, the lower CIA (70) and MIA (71) values and the abundance of plagioclase and detrital zircon grains with preserved euhedral shape <400 Ma suggest that local volcanic rocks in addition to sedimentary covers were eroded. © 2019 Elsevier Ltd},

abstract = {The provenance of top-Famennian sedimentary rocks linked to the Hangenberg Crisis from the northern Rhenish Massif (Germany) was investigated by the means of detrital zircon U-Pb geochronology. Based on the obtained age spectra, three main tectonothermal domains are recognized as possible sources: Paleo- and Mesoproterozoic (~ 2000–1000 Ma) units of Baltica and Early Paleozoic Caledonian orogen (~ 500–400 Ma). Our interpretation of the detritus having been derived from northern source areas, i.e., Baltica and the Scandinavian Caledonides, with a minor input of German-Polish (Rügen-Pomeranian) Caledonides, contradicts the traditional view that, during the Upper Devonian, the northern Rhenish Massif was supplied by detritus from the south. Complementary mineralogical, textural and geochemical analyses point to a derivation of the detritus of Drewer and Hangenberg Sandstones mainly from felsic, recycled continental crust. The elevated concentrations of Pb and Zn in the studied sections are a feature attributed to hydrothermal alteration related to the terminal Devonian synsedimentary volcanism or post-depositional Variscan deformation. © 2018, The Author(s).},

abstract = {Carbonate cobbles from the lower Famennian (crepida conodont Zone) brachiopod shell beds of the Russkiy Brod Quarry (Central Devonian Field; Russia) have been investigated with respect to paleoecology and paleoenvironment. The cobbles, composed of similar shell bioclasts as the host deposits, were eroded from lithified shell beds during intervals of non-deposition. The smooth surfaces and the presence of borings and encrustations on all sides suggest that the cobbles were periodically transported and overturned.The fact that all the bioerosion traces are encrusted and none of the encrusters were bioeroded indicates that the first colonizers of the cobbles were worm-like suspension feeders, leaving long, cylindrical borings (Trypanites). The encrusting organisms are dominated by spirally-coiled microconchid tubeworms, followed by cornulitids, productid brachiopods, hederelloids, foraminifera, enigmatic Ascodictyon and trepostome bryozoans.The high abundance but low-diversity brachiopod fauna and general rarity of such stenohaline taxa as echinoderms in the shell beds or bryozoans on the cobbles suggest that the salinity fluctuated. The presence of dolomite crystals in both the host deposit and cobbles suggests that salinity increased from normal-marine to a higher salinity level during colonization of the cobbles. In fact, as shown by the facies and palynofacies data, the cobble-bearing deposits represent near-shore, restricted environments created during the first phases of transgression of the early Famennian that followed the regional regression at the Frasnian-Famennian transition. In such shallow, restricted settings a higher salinity could have appeared seasonally during a hot and dry climate.As with the microconchids from the aftermath of the end-Permian mass extinction, those from the post-crisis early Famennian interval of Russia were also dominant due to unstable environmental conditions. Here, at least in the case of the Russkiy Brod, the periodic higher salinity episodes may have discouraged other encrusters and thus promoted the settlement of the opportunistic microconchids. © 2014 Elsevier B.V.},

abstract = {A rich and diverse assemblage of arthropods and non-biomineralized macroalgae occurs in the Upper Devonian marine deposits of the Holy Cross Mountains, central Poland. The phrase Kowala Lagerstätte is herein proposed for the fossil-bearing deposits confined to the lower Famennian marly shale and limestone succession of the famous Kowala Quarry. The arthropod fauna is represented by phosphatic exoskeletal remains that still preserve the fine micro-ornamentation of the cuticle. The fauna includes crustaceans and crustacean-like taxa such as thylacocephalans, phyllocarids and angustidontids (in order of abundance). The non-biomineralized algae, represented by at least three morphotypes, occur as carbonaceous compressions of their thalli while still preserving fine details including bundles of thin tubular projections. Although their general appearance is reminiscent of some Early Palaeozoic non-calcified Dasycladales algae, their true taxonomic position is still uncertain. Lithology, as well as faunal and phytoplankton content point to a pelagic sedimentary environment. Impoverished benthic fauna, sediment lamination and geochemical signatures indicate at least periodic bottom-water dysoxic to anoxic conditions. Thus, the preservation of arthropod cuticle and non-calcified algae was primarily governed by oxygen-deficient bottom waters that prevented bioturbation and scavenging during their burial. © 2014 Lethaia Foundation.

A disrupt ion in the colour pattern was also observed to have occurred during ontogenetic shell growth. In this specimen, it appeared in the healed shell damage on the outer lip. So far, only nine Carboniferous species of Naticopsis have been reported with the colour pattern preserved. The most common are the zigzag-type and the spiral band-type. Individual taxa clearly differ in the morphology of the chevrons (direction and angles of breaks) and the location and width of the spiral bands on a whorl. However, the color patterns may not be diagnostic features for the Naticopsis species, because of the large intraspecific variation and colour pattern polymorphism on the neritimorph shells. Colour patterns on Palaeozoic neritimorph shells most likely served as camouflage with respect to the bottom surface in the photic zone.},

abstract = {Oncoids from two localities (Ogrodzieniec and Blanowice) of the Polish Jura, southern Poland, have been investigated with respect to their genesis and paleoecology. These oncoids occur within Middle Jurassic (Bathonian) deposits. Those from Ogrodzieniec are large, elliptical, and embedded within a presumably condensed carbonate bed. Those from Blanowice, on the contrary, are significantly smaller, irregular to box-like in shape, and occur within the ore-bearing clays. The oncoids from both localities consist of a distinct carbonate core and laminated cortex that is significantly thicker and better preserved in the Ogrodzieniec oncoids. SEM and optical microscopic investigation of the oncoid cortices revealed the presence of carbonate and silicate layers with web-like structures similar to those occurring in recent cyanobacterial microbialites. Thus, the oncoid cortices investigated may have formed in a photic zone environment with the aid of coccoid and filamentous cyanobacteria. Oxic conditions prevailed during oncoid cortex formation within the siliciclastic setting, which is manifested by low total organic carbon content, high pristane/phytane (Pr/Ph) ratio, and significant predomination of the C 31 homohopanes. On the cortices' surfaces, as well as between particular laminae, various encrusting organisms have been found. The encrusters, dominated by serpulids and bryozoans, are cryptic species that inhabited the undersides and recesses of the oncoids. Their presence on both the upper and lower surfaces of the oncoids indicates that the oncoids were episodically overturned on the seafloor. The much better developed cortex lamination and much higher diversity and abundance of encrusters in the Ogrodzieniec oncoids may point to better trophic conditions prevailing in a shallower marine environment characterized by transparent waters, as opposed to a deeper siliciclastic environment with less transparent waters and probably worse trophic conditions prevailing during formation of the Blanowice oncoids. © 2011 The Author(s).},

abstract = {Microconchid tubeworms (Tentaculita) encrusting brachiopod shells have been investigated from the upper Frasnian - lower Famennian (Upper Devonian) deposits of the Central Devonian Field, Russia. The condition of microconchids and associated encrusting taxa is reported for the first time from the early Famennian recovery interval (crepida Chron) following the Frasnian-Famennian mass extinction. Two species, one new (Palaeoconchus variabilis sp. nov.) and the second one in open nomenclature (Palaeoconchus sp.), are described. Compared to lower Famennian specimens, they seem to be preferentially grouped on the anterior parts of the brachiopod host shells, which are interpreted as the most suitable sites away from the sea-bottom and sediment. During the late Frasnian (Late rhenana Chron), microconchids, outnumbered by cornulitids and as abundant as foraminifers, were also associated with trepostome bryozoans, tabulates, rugose corals and various problematic encrusters. During the early Famennian recovery interval encompassing the crepida Chron, microconchids greatly outnumbered all associated encrusters, including the previously dominant cornulitids, while foraminifers, tabulates and rugose corals vanished. Early Famennian microconchids, represented by the single, albeit very abundant, species Palaeoconchus variabilis sp. nov., were opportunists that rapidly colonised the environment during the ongoing transgression following the regression-driven biotic crisis in the area of the Central Devonian Field. In comparison to their late Frasnian predecessors and even other Middle Devonian specimens, no size reduction (the so-called Lilliput effect) of early Famennian microconchid tubes was observed. It is probable that microconchids either rapidly attained their 'normal' sizes or they did not suffer any dwarfism following the Frasnian-Famennian event. © The Palaeontological Association.},

abstract = {Tentaculitoid microconchid tubeworms from Devonian (uppermost Emsian-upper Givetian) deposits of the Holy Cross Mountains, Poland, include three new species from stratigraphically well-constrained lithological units: Polonoconchus skalensis n. gen. n. sp., Palaeoconchus sanctacrucensis n. sp. and Microconchus vinni n. sp. The microconchids inhabited fully marine environments during transgressive pulses, as is evidenced from facies and associated fossils. Polonoconchus skalensis n. gen. n. sp. and Palaeoconchus sanctacrucensis n. sp. inhabited secondary firm- to hard-substrates in deeper-water, soft-bottom environments. They developed planispiral, completely substrate-cemented tubes and planispiral tubes with elevated apertures, which is indicative of environments where sedimentation rate is low but competition for space (by overgrowth) may be high. Microconchus vinni n. sp., on the other hand, developed a helically coiled distal portion of the tube as a response to a high sedimentation rate. As the taxonomic composition of Devonian microconchids is poorly recognized at both regional and global scales, this new material contributes significantly to our understanding of the diversity of these extinct tube-dwelling encrusters. © 2011 The Paleontological Society.},

Septation in gastropod shells is a rare phenomenon and is an adaptive feature. Septa occur either in the thick-shelled gastropods living in high-energetic (reef) environments, preventing against negative effects of destruction of the apical parts of shells, or in the thin-shelled gastropods living on muddy substrate, lowering the inner volume of a habitable part of shell and increasing outer surface of gastropod body.},

abstract = {Gastropod response to a marked carbon isotopic geochemical anomaly across the Early-Middle Frasnian transition (Palmatolepis transitans-Palmatolepispunctata conodont zones) has been analysed along the southern Laurussian shelf, mainly within the Dyminy Reef in the Holy Cross Mountains. Gastropods are represented by three reefal associations (Kowalatrochus sanctacrucensis; Euryzone kielcensis; and Grabinopsis guerichi associations), and an impoverished open-shelf Straparollus laevis assemblage. The most severe diversity crisis is connected to the disappearance of local low-energy muddy habitats, as a result of a transgressive pulse (Middlesex Event) and benthic habitat changes tied to strongly fluctuating carbon cycling; this has been observed at the highly diverse Kadzielnia-type assemblage. Fifteen taxa have been recognised in this distinctive Early Frasnian mud-mound association, including six (probably endemics), which are unknown from the Middle Frasnian. The disappearance of three relict Givetian species (Euryzone delphinuloides; Straparollus laevis; and Goniasma? zarecznyi) is also recorded. Other species probably migrated into the shallower water part of Dyminy Reef and persisted in the Middle and Late Frasnian. The Middlesex Event and the earlier major biogeochemical perturbation seem to have less serious effects for evolution of gastropods in the Polish-Moravian part of the Laurussia shelf than the catastrophic Frasnian-Famennian extinction. Two new taxa are described: Frydiella kaimi gen. et sp. nov. (Eotomariidae) and Heidelbergeria czarnieckii gen. et sp. nov. (Elasmonematidae.).},

abstract = {The unique goniatite-rich pyritic level, 1.6 m thick, exposed at Kostomłoty (Holy Cross Mountains; central Poland) represents a distinct, local biotic event in the Early Frasnian interval corresponding to the inception of a major geochemical (carbon cycling) perturbation in the stagnant deep-water and oxygen-deficient Kostomloty basin. The taxonomic and palaeoecologic characteristics of molluscan fossil associations from the Goniatite Level are presented. Most of the goniatitids and orthoconic nautiloids from the studied fossil assemblages are juvenile conchs or protoconchs, or incomplete phragmocones and represent the genera Acanthoclymenia and Linguatornoceras, the former being predominant, and a single adult specimen probably of the genus Koenenites. In contrast, gastropods and bivalves are generally well preserved and identifiable to species level. Two new species are described: a gastropod Palaeozygopleura (Bohemozyga) pyritica sp. nov. and a bivalve Glyptohallicardia multicostata sp. nov. These studied molluscs and also amphiporoids are allochthonous elements which must have been transported into the deeper settings during sea-level rise and flooding of fringing reefs (Timan Event) and/or storm events, and there were mixed with pelagic cephalopods. Probably, a sea-level rise even led to flooding of nearby areas, and thus to introduction of pelagic material (juvenile cephalopods) into reefal settings, and then back to the deeper water again by the quasi-estuarine circulation of water masses.},

abstract = {Frasnian gastropods from the Kowala Formation (north-western part of the Holy Cross Mountains, Poland) form five reef associations and one lagoonal assemblage are described. The distinct influence of regional shallowing-upward cycles on the composition of gastropod fauna have been observed. Composition changes of this fauna were controled by IIb/c, IIc, and IId cycles. Early Frasnian reef association appeared with predominantly thick-shell gastropods, which occur in the upper Sitkówka Beds. At the beginning of IIb/c cycle, Kadzielnia-type mud mounds with a high diversified gastropod association appeared. The next cycles caused the disappearance of mud mounds (IIc), the sinking of the Dyminy reef (IId), and extinction of the gastropod associations from the upper Sitkówka Beds. Two gastropod associations and one poorly diversified lagoonal assemblage predominated in the reef-cap stage. Frasnian reef gastropods have not been observed in the Famennian and Early Carboniferous series. Thus, they probably became extinct together with the collapse of the Frasnian reef ecosystem near the Frasnian-Famennian boundary. Twenty seven taxa have been recognized, among them three new species and two new genera are described: Kowalatrochus sanctacrucensis gen. et sp. nov., Grabinopsis guerichi gen. et sp. nov., and Loxoplocus (Donaldiella) karczewskii sp. nov. Two poorly known Gürich's species have been also revised: Euryzone kielcensis and Orecopia kadzielniae.},
