An Early Carboniferous leaf-colonizing fungus
Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, 2011Documented evidence of fungi inhabiting the leaves of Palaeozoic land plants is rare. This paper describes impressions of rosette-like fungal thalli on a dispersed plant cuticle from the Lower Carboniferous of Chemnitz-Glosa (Germany). Circular structures in the centre of one thallus are interpreted as infection pores.

Loch Macumber (early Carboniferous) of Atlantic Canada
Journal of Paleolimnology, 1994Following the Acadian Orogeny, Atlantic Canada accommodated several, large, relatively deep lakes within a wrench-fault basin complex called the Maritime Basin. Late Devonian and Tournaisian lakes were hydrologically open, shallow to deep, mainly fresh water bodies.

Beaks and radulae of Early Carboniferous goniatites
Lethaia, 1997About one hundred goniatite beaks (jaws) and five radulae from the Late Mississippian (Early Carboniferous) of Arkansas wgere studied with light and scanning electron microscopy (SEM). Four beaks were found within the body chamber of the goniatite Girtyoceras.

Early Carboniferous trilobites (Weaniinae) of eastern Australia
Alcheringa: An Australasian Journal of Palaeontology, 1989Eleven species of Early Carboniferous trilobites are discussed; all have pygidia in which the pleural regions are divided into segments rather than ribs. Five of the species have been redescribed or revised, with a sixth being assigned to a new genus, Thalabaria gen.

Carboniferous–Permian climate change constrained early land vertebrate radiations
Nature Ecology & Evolution, 2019The Carboniferous-Permian transition (CPT) was Earth's last pre-Quaternary icehouse-greenhouse transition, recording major shifts in late Palaeozoic climate regimes and increased continental seasonality over approximately 40 Myr. Its parallels to Quaternary climate change have inspired recent investigations into the impacts of purported rainforest ...

Early Carboniferous Bivalvia from western Argentina
Alcheringa: An Australasian Journal of Palaeontology, 1994Gonzalez, C. R., Early carboniferous Bivalvia from western Argentina. Alcheringa 18, 169–185. ISSN 0311-5518. Lower Carboniferous deposits of western Argentina yield invertebrates and plant remains. In the Tournaisian epoch, a transgression from the ‘Pacific’ flooded the Rio Blanco Basin, forming a semi-restricted inland sea.

Early Carboniferous ophiuroids from Crawfordsville, Indiana
Journal of Paleontology, 1997Molds of numerous Early Carboniferous echinoderms collected by Christian van de Loo for James Hall in 1867 from four miles south of Crawfordsville, Montgomery County, Indiana and now in the collection of the New York State Museum have been examined using latex casting techniques.

Carboniferous Coals from Northern Norway - a Window into the Early Diagenesis of Carboniferous Coals
Proceedings, 1995A Lower Carboniferous coal-bearing succession was penetrated by two shallow cores drilled on the Finnmark Platform off the north toast of Norway, which recovered a total of 210 metres of core. The cored succession consists of a series of erosive, fining upwards fluvial channel sandstones, interbedded with siltstones and carbonaceous shales or coals ...

An early carboniferous flora from Argentina. Biostratigraphic implications
Review of Palaeobotany and Palynology, 1989Abstract A Lower Carboniferous flora from the Del Raton Formation, exposed near Calingasta, San Juan province of Argentina, is described and illustrated and its biostratigraphic significance is evaluated. The megafossils include Lepidodendropsis eximius (Frenguelli) Sessarego et Cesari, Archaeosigillaria conferta (Frenguelli) Menendez, Diplothmema ...

Sediment dynamics of early Carboniferous ramps: A proposal
Geological Journal, 1990AbstractIn this paper we contend that the widespread development of carbonate ramps, in preference to carbonate shelves, during the early Carboniferous was a consequence of the different style of carbonate production during that period. Not only was the overall rate of biogenic production probably slightly lower than at most other times in the ...
