Facies, magnetic susceptibility and timing of the Late Devonian Frasnian/Famennian boundary interval (Xom Nha Formation, Central Vietnam)
(Palaeobiodiversity and Palaeoenvironments, 2021-09-09)Upper Devonian carbonates deposited through the Frasnian/Famennian (F/F) stage boundary in the Xom Nha Formation, Central Vietnam, were studied. The section is mainly composed of fossiliferous, brecciated, and laminated ... -
Fazies, Stratigraphie und Ammonitenfauna des Mittleren und Oberen Dogger bei Neumarkt i.d.Opf. (Bajocium-Oxfordium, Süddeutschland)
(Selbstverlag Fachbereich Geowissenschaften FU Berlin2001)Das Profil Neumarkt-Fuchsberg umfaßt eine 25 m mächtige Sedimentabfolge von flach-subtidalen Sandsteinen des tieferen Bajocium bis zu einer Kalk-Mergel-Wechselfolge des höheren Oxfordium mit Schwamm-Mikrobialithen in ... -
First application of dental microwear texture analysis to infer theropod feeding ecology
(Palaeontology, 2022-12-09)Theropods were the dominating apex predators in most Jurassic and Cretaceous terrestrial ecosystems. Their feeding ecology has always been of great interest, and new computational methods have yielded more detailed ... -
First record of the Early Carboniferous ammonoid genus Goniatites from the Greater Karatau (Kazakhstan palaeocontinent)
(Palaeobiodiversity and Palaeoenvironments, 2020-07-24)The Late Viséan ammonoid genus Goniatites had a near-global distribution within the tropical seas but was rarely reported from Central Asia. New investigations of the Early Carboniferous sedimentary succession in the Greater ... -
Flexible habitat choice of pelagic bacteria increases system stability and energy flow through the microbial loop
(Limnology and Oceanography, 2022-04-19)Pelagic bacteria can be classified into free‐living and particle‐attached life modes, which either dwell in the water column or attach to suspended particles. Bacteria with a generalist life style, however, can actively ... -
Fluorescent colour patterns in the basal pectinid Pleuronectites from the Middle Triassic of Central Europe: origin, fate and taxonomic implications of fluorescence
(Palaeontology, 2022-10-27)UV light‐induced fluorescence is widely used as a key to reveal residual shell colour patterns of Neogene and Palaeogene molluscs. However, only few examples of fluorescent colour patterns are known from Mesozoic marine ... -
Food in a colonial setting: the flora assemblage of a short-lived Seleucid-founded site in the Near East
(Vegetation History and Archaeobotany, 2021-01-31)In this paper we present the analysis of archaeobotanical material retrieved by means of flotation from well-secured features during recent excavation work carried out in 2019 and 2020 by the German-Israeli Tell Iẓṭabba ... -

Fossilized soft tissues in Palaeozoic bryozoans
(Papers in Palaeontology, 2023-02-23)Thin sections of three Palaeozoic bryozoans reveal fossilized soft tissues that show the position of organic cuticle and internal structures such as the membranous sac and gut. The fossilization occurred apparently due to ... -
Four millennia of vegetation and environmental history above the Hyrcanian forest, northern Iran
(Vegetation History and Archaeobotany, 2020-11-29)Past vegetation, fire, and climate dynamics, as well as human impact, have been reconstructed for the first time in the highlands of the Gilan province in the Alborz mountains (above the Hyrcanian forest) for the last ... -
Frutexites-like structures formed by iron oxidizing biofilms in the continental subsurface (Äspö Hard Rock Laboratory, Sweden)
(PLOS ONE, 2017)Stromatolitic iron-rich structures have been reported from many ancient environments and are often described as Frutexites, a cryptic microfossil. Although microbial formation of such structures is likely, a clear relation ... -
Genetic and morphologic determination of diatom community composition in surface sediments from glacial and thermokarst lakes in the Siberian Arctic
(Journal of Paleolimnology, 2020-05-30)Lakes cover large parts of the climatically sensitive Arctic landscape and respond rapidly to environmental change. Arctic lakes have different origins and include the predominant thermokarst lakes, which are small, young ... -
Geoteuthinus muensteri (d'Orbigny 1845) aus dem Untertithonium von Daiting und Arnsberg (Bayern)
(Stuttgarter Beiträge zur Naturkunde : Serie B, Geologie und Paläontologie, 1983)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 ... -

Gradual warming prior to the end‐Permian mass extinction
(Palaeontology, 2022-09-06)The biggest known mass extinction in the history of animal life occurred at the Permian–Triassic boundary and has often been linked to global warming. Previous studies have suggested that a geologically rapid (<40 kyr) ... -
Growth of microaerophilic Fe(II)‐oxidizing bacteria using Fe(II) produced by Fe(III) photoreduction
(Geobiology, 2022-01-11)Iron(II) (Fe(II)) can be formed by abiotic Fe(III) photoreduction, particularly when Fe(III) is organically complexed. Light‐influenced environments often overlap or even coincide with oxic or microoxic geochemical conditions, ... -
Growth response of calcifying marine epibionts to biogenic pH fluctuations and global ocean acidification scenarios
(Limnology and Oceanography, 2020-12-17)In coastal marine environments, physical and biological forces can cause dynamic pH fluctuations from microscale (diffusive boundary layer [DBL]) up to ecosystem‐scale (benthic boundary layer [BBL]). In the face of ocean ... -
High Precision Femtosecond Laser Ablation ICP‐MS Measurement of Benthic Foraminiferal Mn‐Incorporation for Paleoenvironmental Reconstruction: A Case Study From the Plio‐Pleistocene Caribbean Sea
(Geochemistry, Geophysics, Geosystems, 2022-10-04)Closure of the Central American Seaway (CAS) and hydrology of the Caribbean Sea triggered Northern Hemisphere Glaciation and played an important role in the Pliocene to modern‐day climate re‐establishing the deep and surface ...
