Summary: This article presents the research findings and analysis of the Frasnian ammonoid fauna from Biidesheim. The fauna contains 25 species of tornoceratid ammonoids, including seven new species and one new genus. The study reveals a remarkably high alpha diversity of tornoceratid ammonoids in the upper Frasnian, which remained high until the Upper Kellwasser Event.

Summary: Seven fenestrate bryozoans from the Middle Devonian of the Eifel were described, with three species identified and four in open nomenclature. Analysis showed a relatively high level of endemism in the distribution of these fossils, with some connections to the Devonian of Europe and Asia. The studied association displayed similarities to the contemporary fauna from Sauerland.

Summary: The study investigates the sedimentation, extinction, and post-reefal facies history of the Hagen-Balve Reef. It reveals that the carbonate accumulation rate in the region was affected by the global Frasnes Events, which led to reef extinction. Additionally, the study identifies several microfacies types that suggest both shallow and deep-water environments in the area.

Summary: The Lower Devonian Klerf Formation in western Germany's Eifel area is an exceptional fossil site with a diverse range of fossils including arthropods, fishes, plants, molluscs, brachiopods, and crinoids. Our study focused on the microflora and microfauna, revealing a well-developed Psilophyton-type vegetation and identifying potential plant species like Leclercqia and Pertica.

Summary: The Balduinstein Reef in the Givetian period developed on mixed felsic lavas and volcaniclastic tuffs. It was influenced by volcanism, erosion, and sea-level changes, and controlled mainly by regional tectonics and volcanic activity.

Summary: The Frasnian ammonoid fauna from Budesheim in the Eifel Mountains has been studied for nearly 200 years but the tornoceratids have never been subject to a monographic study. A new fauna from the Upper Devonian I-K level yielded a large number of tornoceratid specimens, which were investigated in terms of taxonomy and morphometry. The results show that tornoceratid ammonoids in the upper Frasnian have exceptionally high alpha diversity, similar to the local gephuroceratoids.

Summary: The Borkewehr section is the best and most complete Devonian/Carboniferous Boundary succession in the Rhenish Massif of Germany. It provides important data on stratigraphy, biostratigraphy, and climate change, which contributes to the understanding of global geological and biological evolution.

Summary: The Drewer quarry in the Rhenish Massif contains Upper Devonian to Lower Carboniferous strata and two black shale intervals associated with global oceanic anoxic events. Investigating the phosphatic concretions within the black shales, researchers found evidence of microbial mats and phosphatic microstromatolites formed under anoxic conditions. The presence of iron sulfides within the microstromatolites suggests that anaerobic, chemotrophic microbial communities were present during the deposition of the Lower Alum Shale.

Summary: This article describes a new Periechocrinidae camerate crinoid, Pulchercrinus hardyi n. gen., n. sp., from the Lower Devonian Seifen Formation of the Rhenish Massif in the western Westerwald Mountains, Germany. The arm rays of this new Periechocrinidae intersect with some genera in the Scyphocrinitidae and the Marhoumacrinitidae, expanding the morphological disparity of the Periechocrinidae.

Summary: The Rhenish Massif in Central Europe, specifically the Eifel Volcanic Fields, has shown ongoing ground deformation and signs of possible unrest. This study explores the possibility of melt accumulation in the crust/lithospheric mantle as an explanation for the observed deformation. The results suggest that sub-horizontal sill-like structures with melt accumulation are responsible for the deformation. The study also discusses the limitations and potential interpretations of the findings, as well as the need for further observations to better understand the magmatic system in the Rhenish Massif.

Summary: The first phalangiotarbid and trigonotarbid arachnids from Waxweiler and Luxembourg, respectively, have been recorded and described. These findings expand the known geographical distribution of these rare Devonian terrestrial arachnids. Additionally, previously unknown anatomical details of Devonotarbus, such as leg podomeres with dense hair-like structures, have been illustrated and briefly described.

Summary: Resinites from karst structures in limestone quarries in the Rhenish Massif were analyzed to determine their plant sources and depositional history. The results showed that these resinites were derived from conifer trees and underwent alteration before transportation and burial.

Summary: This study reviews 30 Devonian-Carboniferous Boundary sections of the Rhenish Slate Mountains and adjacent subsurface areas, focusing on litho-, event, conodont, ammonoid, sequence, and chemostratigraphy. It refines the terminology of the Hangenberg Crisis Interval and distinguishes various conodont and ammonoid zones within different intervals. The study also highlights the subdivision and characteristics of different subzones within the defined intervals.

Summary: A new zosterophyllopsid species, named Zosterophyllum confertum sp. nov., is described from the Lower Devonian of the central Rhenish Massif. This species is characterized by its construction of fertile parts and compact and terminally positioned mature strobili, which have up to seven rows of helically and counter clockwise inserted sporangia.

Summary: The Hagen-Balve Reef Complex in the northern Rhenish Massif of Germany is an important example of Givetian to Frasnian reefs. This study focused on the Binolen Member, analyzing microfacies, micro-, and macrofaunas to understand the facies development and changing distribution patterns. The research provides valuable insights into the reef development in the Rhenish Massif and beyond.
