Early Carboniferous brachiopod zones of eastern Australia
Journal of the Geological Society of Australia, 1975Abstract The Early Carboniferous brachiopod zones of eastern Australia are defined from reference sections in New South Wales. The zones include the Tulcumbella tenuistriata, Spirifer sol, Schellwienella cf. burlingtonensis, Orthotetes australis, Delepinea aspinosa, and Rhipidomella fortimuscula Zones. Two contain subzones: the Pustula gracilis Subzone

Carboniferous and Early Permian Magmatism in England
Journal of PetrologyAbstract The cause of widespread Carboniferous and Early Permian magmatism that occurred across Northern Europe and the UK remains enigmatic. New 40Ar-39Ar radiometric dating reveals that some of the earliest manifestations of alkaline to sub-alkaline magmatism, found near the southern limit of the province in the Peak District of ...

Bark Anatomy of an Early Carboniferous Tree from Australia
IAWA Journal, 2013Our knowledge of the evolution of secondary phloem and periderm anatomy in early lignophytes (progymnosperms and seed plants) is limited by the scarcity of well-preserved fossil bark. Here, I describe the bark of a Mississippian (Early Carboniferous) tree from Australia based on macro- and microscopic observation of two permineralized specimens.

The Early Carboniferous Magerøy Dykes, Northern Norway: Palaeomagnetism and Palaeogeography
8th SAGA Biennial Technical Meeting and Exhibition, 2003Palaeomagnetic data from the 337 Ma Magerøy dykes (northern Norway) are of exceptionally high quality, and a positive contact test along with an existing regional result from the Silurian Honningsvåg Igneous Suite attests to a primary Early Carboniferous magnetic signature.

Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, 2011
Previous conodont studies on the Devonian/Carboniferous (D/C) boundary revealed that the current definition of the D/C boundary cannot be maintained due to several problems relating to the index taxon. The base of the Carboniferous System is defined by the first occurrence of the conodont species Siphonodella sulcata, within the S.

Devonian – Early Carboniferous Deformation and Metamorphism, North Greenland
1991Abstract As outlined above (Chapters 7, 8), the sedimentary subprovince of the Franklinian deep water basin (Hazen Trough) extends eastward from the Canadian Arctic Islands (Chapter 8C) into northern Greenland (Chapter 7), and the pulses of deformation which affected the Canadian sector (Hazen Fold Belt) in Late Silurian or Devonian to ...

Distribution, evolution and extinction of global early Carboniferous flora
Journal of Palaeosciences, 1994The uniform Lepidodendropsis flora of the Early Carboniferous is uniformly and widely distributed in the Cathaysia, Laurasia, Kazakhstania and Gondwana continents. This is characterized by Lepidodendropsis, Sublepidodendron, Archaeosigillaria, Archaeocalamites, Sphenopteridium, Cardiopteridium, Rhodeopteridium, Rhacopteris, Triphyllopteris and ...

Early Carboniferous Bryozoans from Western Siberia, Russia
2012A diverse bryozoan fauna is described from two boreholes from the Kurgan Region, Russia, containing rocks of Lower Carboniferous (Tournaisian-Visean) age. The bryozoan assemblage includes 13 fenestellids and 5 rhabdomesines, of which one species is new: Pseudonematopora sibirica n. sp.

Early Carboniferous plants of the Arkhangelsk Region, Russia
Paleontological Journal, 2007Eight species of fossil plants are described for the first time from the Lower Carboniferous of the Arkhangelsk Region. One of these species, Adiantites lisitzynii O. Orlova et Jurina, is new. The taxonomic composition of the assemblage of 20 species indicates a woody vegetation of the Euramerian aspect. The rich assemblage recovered for the first time
