Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.Abstract In the Csővár area of north‐central Hungary a remarkably well‐preserved Rhaetian radiolarian fauna, in which conodonts were also found, has enabled the identification of 49 radiolarian species belonging to 35 genera. The fauna is dominated by the orders Spumellaria and Entactinaria over less diverse Nassellaria.

Carnets de Géologie, 2010 In central Tunisia near the village of Ellès is Wadi Ed Dam. There the Abiod Formation, underlain by the Kef marls and capped by the El Haria marls, crops out in an almost uninterrupted exposure about 286 m thick.

Oxfordian and Kimmeridgian "Aspidoceras" in the Mediterranean. A methodological approach
Estudios Geologicos, 1987 En el presente trabajo se lleva a cabo un análisis contrastador de la Hipótesis Nula establecida como base metodológica para la investigación evolutiva de los"Aspidoceras" mediterráneos (Checa & Olóriz, 1985).

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.Abstract During the Kimmeridgian, the Wealdian Basin experienced several periodic disaerobic events, interpreted as the result of extensive rainfall patterns, high sea level and moderate stratification of the water column. These events are recorded in different regions of UK and France.

Geologica Carpathica, 2017 The present contribution deals with the taxonomy of seven species of perisphinctoid ammonite from the Štramberk Limestone (Outer Western Carpathians, Czech Republic) deposited in Moravian-Silesian museums.

A Tropically Hot Late Jurassic North American Sundance Sea: Evidence for the Oxfordian Warm Interval
Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.Abstract The Late Jurassic greenhouse climate was characterized by elevated atmospheric CO2 (pCO2) at 600–1,000 ppm and sea‐surface temperatures substantially warmer than today. These conditions peaked during the Oxfordian, when extensive epicontinental seaways, including the North American Sundance Sea, dominated mid‐latitude paleoceanography.

Holostratigraphy of the Kahmah regional Series in Oman, Qatar, and the United Arab Emirates
Carnets de Géologie, 2008 The stratigraphic framework of the uppermost Jurassic - Lower Cretaceous interval of the Gulf area is revised using both historical and recently acquired paleontological (ammonites, calpionellids, foraminifers, 'calcareous' algae), sedimentological and ...

The Origin of Carbonate Magmas Predating and Accompanying Main‐Phase LIPs Eruptions
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract Some large igneous provinces (LIPs) are associated with precursory carbonatite eruptions. Models for precursory carbonatites invoking partial melting of a carbonate metasomatized lithosphere appear implausible, given the long time needed for heat conduction from the plume head.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract The Valanginian positive carbon isotope excursion (Weissert Event, ca. 135 million years ago) documents a major global carbon cycle and climate perturbation. Radioisotopic dating suggests that this event was broadly contemporaneous with an interval of profoundly enhanced volcanic activity during the emplacement of the Paraná–Etendeka Large ...

European Journal of Geography, 2017 In this study we introduce teaching proposals to “inject” ammonite fossils, in the Geography syllabus, as evidence of Greek paleoenvironment, which at the moment is the only existing geoscience subject of Greek primary curriculum.
