Abstract The loss of carbonate production during the Toarcian Oceanic Anoxic Event (T-OAE, ca. 183 Ma) is hypothesized to have been at least partly triggered by ocean acidification linked magmatism from Karoo-Ferrar large igneous province (southern Africa and Antarctica). However, dynamics never directly quantified across T-OAE. Here, we present first record temporal evolution seawater pH spanning late Pliensbachian early Lusitanian Basin (Portugal) reconstructed on basis boron isotopic...
Abstract: A decapod crustacean faunule from the lower Miocene (upper Burdigalian, ‘Karpatian’) of Slovakian part Vienna Basin comprise five new species: Callianopsis marianae (Ctenochelidae), Crosniera schweitzerae (Thomassiniidae), Agononida cerovensis and Munidopsis lieskovensis (both Galatheidae) plus Mursia harnicari (Calappidae). The species is first undoubted member genus to be recorded Europe; it based on sexually dimorphic major minor chelae as well portions carapace abdomen. sp....
Abstract A well preserved Upper Tithonian–Lower Berriasian Strapkova sequence of hemipelagic limestones improves our understanding environmental changes occurring at the Jurassic/Cretaceous boundary in Western Carpathians. Three dinoflagellate and four calpionellid zones have been recognized section. The onset Alpina Subzone standard Calpionella Zone, used as a marker is defined by morphological change alpina tests. Calpionellids calcified radiolarians numerically dominate microplankton...
The dependence of skeletal alteration on time spent in the taphonomic active zone (TAZ) can generate a clock, which be used to quantify scales averaging and rates production recycling fossil record. However, strength clock is variable present-day shallow marine environments it unclear how this varies with depth. Here, we assess Nautilus macromphalus dead shells that were collected cool-water, sediment-starved, epi- mesobathyal off New Caledonia range postmortem age from few decades several...
Sampling of latest Burdigalian (Miocene) silty clays from the Malé Karpaty Mountains in Slovakia revealed a deep-water, low diversity shark fauna.The fauna is dominated by teeth very small squaliform sharks, including two new species, Eosqualiolus skrovinai sp.nov.and Paraetmopterus horvathi sp.nov.The generic composition more similar to that known Eocene than today, suggesting post-early Miocene faunal turnover within this clade, at least locally.Nectobenthic, non sharks are rare, but...
Abstract: Isopod crustaceans are rarely preserved in the fossil record. Herein, an appraisal of record for cirolanid isopods is presented. Five genera briefly discussed, including Bathynomus , Brunnaega Palaega Pseudopalaega and Cirolana . A key known to date from provided based mostly on pleotelson characters. From early Miocene Slovak part Vienna Basin, feldmanni sp. nov. described being only fifth species one few with appendages. The material exhibits preservation suggesting biphasic...
A late Burdigalian bathyal mollusc fauna from the Vienna Basin (Slovakia) This is first record of a Early Miocene Central Paratethys. The assemblage shows clear affinities to coeval faunas Turin Hills in Mediterranean area and Aquitaine France. overall biostratigraphic value hard estimate due general very poor knowledge faunas. Several species, however, are known deep water deposits Middle Badenian stage as well. implies roots parts suggests low turnover for communities at Early-Middle...
The chemostratigraphic record of the Toarcian Oceanic Anoxic Event (T-OAE) is generally well documented in epicontinental basins; however, duration anoxia and recovery remains poorly constrained Tethys Ocean owing to limited stratigraphic resolution oceanic sections with hiatuses. In this paper, we describe a relatively continuous hemipelagic Central Western Carpathians Slovakia (Skladaná Skala section), which contains Pliensbachian/Toarcian boundary, T-OAE, subsequent phase. our section,...
Upper Jurassic ammonoid shell concentrations on pelagic carbonate platforms formed by the mixture of well-preserved and moldic shells provide a unique opportunity to evaluate effects average durability productivity variations in abundance preserved fossil record. High primary cement has significantly negative statistical taphonomic alteration, reducing proportion affected Fe-staining syndepositional dissolution. proportions internal borings indicate that were not rapidly buried....
A Lower Tithonian cavity-dwelling community from pelagic carbonate platform deposits of the Czorsztyn Unit, Western Carpathians, represents a succession mostly solitary coelobite organisms, dominated by scleractinian corals and small-sized serpulids during initial recruitment stage, following stages. These bioconstructors were accompanied with other suspension feeders: thecideidine brachiopods, oysters, bryozoans, sponges, crinoids sessile foraminifers. The boundary between first second...
Here we report, for the first time, a very rich and diversified sponge assemblage from late Early Miocene deposits of central part Vienna Basin (Paratethys) in Slovakia. Bodily preserved sponges are described as new genus species Paracinachyrella fossilis (Tetiliidae, Demospongiae). Dissociated spicules reveal presence "soft" demosponges that belong to families Tetillidae, Theneidae, Geodiidae, Samidae, Thrombidae, Thoosidae, Agelasidae, Myxillidae, Bubaridae, Tedaniidae, lithistid family...
Caves in arenites of the Roraima Group Venezuela have been explored on Chimantá and plateaus (tepuis). Geological geomorphological research showed that most feasible method caves genesis was winnowing erosion unlithified or poorly lithified arenites. The arenitic beds were isolated by well-cemented overlying underlying rocks. There is a sharp contrast between these well-lithified rocks loose sands which form to beds. They are only penetrated strongly pillars cemented vertical finger flow...
