In the External Zone of Betic Cordillera (S Spain), upper Muschelkalk (Ladinian) facies have been known for decades; however, so far there is no stratigraphic record Anisian deposits. present study, new biostratigraphic data from a carbonate succession in easternmost Subbetic domain reveal Pelsonian-Illyrian (Anisian) age. The nautiloids Germanonautilus salinarius and saharonicus are documented...

Abstract The scarce evidence of paleontological records between the upper Permian and Anisian (Middle Triassic) Western Europe could reflect (1) large stratigraphic gaps in continental successions and/or (2) persistence disturbed conditions after Permian–Triassic Boundary extinction event succession ecological crises that occurred during Early Triassic. In this context, study palynological asso...

Nothosaurs form a subclade of the secondarily marine Sauropterygia that was well represented in late Early to early Late Triassic marine ecosystems. Here we present and discuss the internal skull anatomy of the small piscivorous nothosaur Nothosaurus marchicus from coastal to shallow marine Lower Muschelkalk deposits (Anisian) of Winterswijk, The Netherlands, which represents the oldest sauropt...

The investigation of mass movements is major interest in mountain regions as these events represent a significant hazard for people and cause severe damage to crucial infrastructure. torrential rainfall event that mainly occurred on the 14 July 2021 western Central Europe not only led flooding catastrophes (e.g., Meuse, Ahr Erft rivers) but also triggered hundreds low range. Here, we investigat...

Following the end-Permian crisis, microbialites were ubiquitous worldwide. For instance, Triassic deposits in Germanic Basin provide a rich record of stromatolites as well microbe-metazoan build-ups with nonspicular demosponges. Despite their palaeoecological significance, however, all these have only rarely been studied. This study aims to fill this gap by examining and comparing from Upper Bu...

Abstract One key aspect in the energy transition is to use deep geothermal stored sedimentary basins as well igneous and metamorphic basement rocks. To estimate variability of potentials across different geological domains encountered Federal State Hesse (Germany), it necessary understand driving processes fluid flow heat transport affecting subsurface temperature variations. In this study, we ...
