Abstract. A new trigonotarbid (Arachnida: Trigonotarbida: Trigonotarbidae) is described as Archaeomartus roessleri n. sp. from the Upper Carboniferous (Pennsylvanian; Namurian B, higher Marsdenian) of Hagen-Vorhalle, Germany. Originally assigned to Trigonotarbus johnsoni Pocock, 1911, our new fossil has a distinctly lobed carapace and thus resembles more closely the Early Devonian species Archaeomartus levis Størmer, 1970. In carapace morphology Archaeomartus approaches the condition seen in the larger and more heavily-armoured taxa Eophrynidae, Kreischeriidae and Aphantomartidae. Thus we prov

AbstractThe hydrocarbon systems of the Mesozoic, inverted West Netherlands Basin have been analyzed using 2-D forward modelling. Three source rocks are considered in the modelling: Lower Jurassic oil-prone shales, Westphalian gas-prone coal deposits, and Lower Namurian oil-prone shales. The Lower Namurian hydrocarbon system of the basin is discussed for the first time.According to the modelling results of the Early Jurassic oil system, the oil accumulations were filled just after the main inversion event. Their predicted locations are in agreement with exploration results. Modelling results of

Together with other described archaeorthopterids, this new specimen further demonstrated considerable diversity of this group in Namurian ecosystems. However, C. liuae gen. et sp. nov.

Abstract:

Analysis of an exhaustive data base of Namurian ammonoid shell characters indicates that the morphology of the Goniatitida can be explained in terms of functional constraints, resulting particularly from hydrostatic and hydrodynamic properties. Modes of life ranging from benthic to pelagic are inferred on this basis for various goniatitid morphotypes; all morphologic features and facies associations are normally compatible with these inferences. Neutral buoyancy is shown to have been likely for all goniatitids. By contrast, the prolecanitids (Order Agoniatitida) exhibit a number of hydrostatic

Abstract:

Abstract3D basin and petroleum system modelling covering the NW German North Sea (Entenschnabel) was performed to reconstruct the thermal history, maturity and petroleum generation of three potential source rocks, namely the Namurian–Visean coals, the Lower Jurassic Posidonia Shale and the Upper Jurassic Hot Shale.Modelling results indicate that the NW study area did not experience the Late Jurassic heat flow peak of rifting as in the Central Graben. Therefore, two distinct heat flow histories are needed since the Late Jurassic to achieve a match between measured and calculated vitrinite refle

Abstract:

Palynostratigraphic study of the Bear Gulch Member of the Heath Formation, central Montana, indicates an Upper Mississippian age for the deposit corresponding to Carboniferous palynofloral zone TK (ammonoid zone E2b, Namurian A). The palynoflora contains a diverse spore assemblage, including the Mississippian index Tripartites vetustus. In addition, the Bear Gulch Member contains an abundant and diverse acritarch assemblage. The age assignment is consistent with age determinations from studies of the ammonoid, conodont, and bryozoan faunas.

Abstract:

Isolated amphibian bones are preserved in freshwater sediments of the Namurian A Pomquet Formation near Grand Étang, Nova Scotia. This assemblage resembles other late Mississippian lakebed or estuarine faunas in that most of the remains can be confidently attributed to one or more taxa of embolomere (order Anthracosauria) or to the order Colosteoidea, although they are indeterminate at the level of genus and species. However, a number of tetrapod elements of uncertain affinities suggests a much more diverse fauna.

Abstract:

The Merksplas-Beerse well (North Belgium) is a low-enthalpy geothermal production well targeting the Dinantian karstic limestones to a total depth of 1761 m. The presence of methane gas in these limestones generated a particular interest in this well. This paper describes the geological profile of this well and the Dinantian reservoir. The Namurian-Visean boundary at 1630 m is determined by the base of the dipmeter draping pattern in the radioactive Chokier shales (base of the Namurian) on top of the karstified Dinantian limestone. The stratigraphic composition of the transitional interval fro
