The paleoecology, habitats, and stratigraphic range of the enigmatic cretaceous brachiopod peregrinella.
- PloS one
Modern and Cenozoic deep-sea hydrothermal-vent and methane-seep communities are dominated by large tubeworms, bivalves and gastropods. In contrast, many Early Cretaceous seep communities were dominated by the largest ...
Microbial carbonate crusts - a key to the environmental analysis of fossil spongiolites?
Morphological and geochemical comparisons between modern cryptic microbialites from Lizard Island/Great Barrier Reef and fossil counterparts in the Upper Jurassic (Southern Germany, Dobrogea/Romania) and late Lower Cretaceous ...
Ecological and socio-economic functions across tropical land use systems after rainforest conversion
- Philosophical Transactions of the Royal Society B: Biological Sciences
Tropical lowland rainforests are increasingly threatened by the expansion of agriculture and the extraction of natural resources. In Jambi Province, Indonesia, the interdisciplinary EFForTS project focuses on the ecological ...
The impact of different proportions of a treated effluent on the biotransformation of selected micro-contaminants in river water microcosms.
- International journal of environmental research and public health
Attenuation of micro-contaminants is a very complex field in environmental science and evidence suggests that biodegradation rates of micro-contaminants in the aqueous environment depend on the water matrix. The focus of ...
Die "Weichteilbelemniten" des Posidonienschiefers (Untertoarcium) von Holzmaden (Baden-Württemberg) sind Fälschungen
- Neues Jahrbuch für Geologie und Paläontologie,
The "soft-part-belemnites" In the Holzmaden Posidonia Shales are forged. · Soft-parts of Phragmoteuthis conocauda (QUENSTEDT) have been compounded with belemnite rostra of Passaloteuthis paxillosa (SCHLOTHEIM). The ...

- Stuttgarter Beiträge zur Naturkunde : Serie B, Geologie und Paläontologie
A description of two recently collected specimens of the rare teuthid species Geoteuthinus muensteri (D'ORBIGNY 1845) from the Lower Tithonian (nMörnsheimer Schichten") of Daiting and Arnsberg (Bavaria) is given. The ...
Chitinobelus acifer Fischer 1981, ein Belemnoteuthide (Coleoidea) mit Epirostrum
- Neues Jahrbuch für Geologie und Paläontologie
The "unusual belemnite" Chitinobelus acifer FISCHER with an "almost purely organic, pinlike epirostrum" and a "calcitic primary rostrum" (FISCHER 1981: 142) is attributed to the order Belemnoteuthida STOLLEY 1919. ...
Polyphase exhumation in the western Qinling Mountains, China: Rapid Early Cretaceous cooling along a lithospheric-scale tear fault and pulsed Cenozoic uplift
The western sector of the Qinling–Dabie orogenic belt plays a key role in both Late Jurassic to Early Cretaceous “Yanshanian” intracontinental tectonics and Cenozoic lateral escape triggered by India–Asia collision. The ...
Hydrated sub-arc mantle: a source for the Kluchevskoy volcano, Kamchatka/Russia
- Earth and Planetary Science Letters
Oxygen isotope ratios of olivine and clinopyroxene phenocrysts from the Kluchevskoy volcano in Kamchatka have been studied by CO2 and ArF laser techniques. Measured δ18O values of 5.8–7.1‰ for olivine and 6.2–7.5‰ for ...
