The ammonoids of the suborder Gephuroceratina from the Roteisenstein (Red Ironstone) Formation of the area around Dillenburg (eastern Rhenish Mountains) are revised, mainly based on historical collections stored in the Museum für Naturkunde, Berlin. The

Abstract In the French Armorican Massif, the Bretonian phase of the Variscan orogeny has been defined by the Late Devonian (Famennian‐Frasnian) erosion gap, and the Early Carboniferous (Tournaisian) syntectonic terrigenous deposits of the l’Huisserie formation in the Laval basin in the Central‐North Armorican Domain, ascribed to the Armorica ...

How to engineer a habitable planet: the rise of marine ecosystem engineers through the Phanerozoic
Abstract Ecosystem engineers are organisms that modify their physical habitats in a way that alters resource availability and the structure of the communities they live in. The evolution of ecosystem engineers over the course of Earth history has thus been suggested to have been a driver of macroevolutionary and macroecological changes that are ...

Abstract Trigonotarbida, an extinct order of spider‐like arachnids, were significant predators between the late Silurian and early Permian. Characterized by their segmented opisthosoma, clasp‐knife chelicera, and paired book lungs, they played a pivotal role in the formation of Early Devonian terrestrial ecosystems.

GIVETIAN BRACHIOPOD FAUNAS OF THE PALENTIAN DOMAIN (N SPAIN)
The origin, evolution, structural and stratigraphical features of the Palentian Domain (Cantabrian Mountains, N Spain) are summarily described. The boundaries of the Givetian succession (ca. 40 m thick) in that area are established from previously known conodont and ammonoid data.

How pterygotid sea scorpions used their tripartite elongate cheliceres to get prey items close to the mouth region remains a conundrum. We applied four different 3D kinematic settings with regard to insertion and orientation of the cheliceres to examine the most likely way this was realized.

Paleoenvironment and age of Los Monos Formation (Devonian), Tarija Basin, Argentina and Bolivia
The objective of this work is to discuss the paleoenvironment and age of the Los Monos Formation, in outcrop and subsurface, along a regional transect (west-east) in the southern sector of the Tarija basin.

Abstract The Lizard ophiolite, Cornwall, South‐West England, is the largest and best‐preserved ophiolite within the Variscan orogenic belt. It forms part of the Rheic‐Rhenohercynian suture zone, and was obducted northwestward onto the passive continental margin of Avalonia (Laurussia) during the Middle Devonian.
