Abstract The geomagnetic polarity pattern for the Carboniferous is incompletely known with best-resolved parts in Serpukhovian and Bashkirian. Hence, data from both igneous sedimentary units are also used an additional bias evaluation. In Tournaisian to mid Visean interval mainly derived palaeopole-type palaeomagnetic studies, allowing identification of chrons. Seven chrons exist Mississippian ...

The paper focuses on the taxonomic description of lower Carboniferous (uppermost Tournaisian to middle Visean) solitary rugose corals from bedded limestone and shale units in Flett Formation Jackfish Gap (eastern Liard Range), northwestern Canada. described herein include 12 species representing the genera Ankhelasma Sando, 1961, Bradyphyllum Grabau, 1928, Caninophyllum Lewis, 1929, Cyathaxonia...

Abstract The Jebel Begaa region of the eastern Anti-Atlas in SE Morocco yielded a single, very well-preserved goniatite that is closely related to Helicocyclus divergens Riley, 1996 from lower Viséan (Chadian) northern England. Both are placed new genus, Tectocyclus n. gen., with Moroccan T. herbigi sp. as type species. Characteristic its subtriangular suture elements, which distinguish it stro...

The Lower Mississippian (Tournaisian) Ballagan Formation in SE Scotland yields tetrapod fossils that provide fresh insights into the critical period when these animals first moved onto land. The key to understanding the palaeoenvironments where they lived is a detailed analysis of the sedimentary architecture of this formation, one of the thickest and most completely documented examples of a co...

Gondwanan floras of Late Devonian age are poorly known. In Australia, the rare studies that have been published on plants old and need reinvestigation. This paper is an account plant macro- micro-remains found in Mandowa Mudstone at Barraba, New South Wales. According to miospores, late latest Famennian age. The record anatomically preserved specimens diversified, with nine taxa assigned Lycops...

Abstract The eastern Anti-Atlas of Morocco represents one the most completely exposed and perfectly documented biostratigraphic records entire Devonian worldwide. Paleogeographically it is clearly differentiated into shallow basins, pelagic platforms, land areas which are newly defined illustrated, from top Middle Devonian, other middle Famennian as two characteristic intervals. dominant paleog...

The aim of this study was to establish the stratigraphic extent a putative Tournaisian Stage within Carboniferous succession in Lublin Basin. oldest part succession, known as Huczwa Formation and comprising depositional sequences 1–4, investigated based on lithofacies analysis, sequence stratigraphy petrographic studies. article provides descriptions sequences, parasequences (cyclothems) that w...
