A Presumed Ascomycete from the Upper Carboniferous

Nature, 1953
THIS fungus was found during a recent examination of a single section cut from a coal ball collected at the Moorside Colliery, near Halifax, Yorkshire. The section has been in the departmental teaching collection at Glasgow for many years; but it has rarely been examined as it does not contain interesting specimens of other plants.

Plant/animal interactions during the upper carboniferous

The Botanical Review, 1983
This paper discusses evidence for plant/animal relationships in the Upper Carboniferous. Close interactions are examined from the study of fossil plants and animals preserved in coal swamp and coastal plain environments. Evidence for plant/animal interactions is in the form of: (1) animal morphology, including both vertebrates and invertebrates.

Seasonal Sedimentation in the Upper Carboniferous of England

The Journal of Geology, 1980
The sequence of sediments between two Upper Carboniferous (Westphalian A) coals in the Lancashire Coalfield is described with particular reference to Ravenhead Quarry, near Wigan. Part of this succession consists of regularly-bedded laminated sandstone/siltstone units containing non-marine bivalves and their escape shafts.

RATES OF SEDIMENTATION IN THE UPPER CARBONIFEROUS OF BRITAIN

Lethaia, 1970
Rate of sedimentation of the Gastrioceras cancellatum marine band (Namurian) is deduced from evidence of shell size, population density, and features of the enclosing sediment. Slowest sedimentation apparently coincided with stagnant water conditions.

An Upper Carboniferous tonstein of volcanic origin

Sedimentology, 1973
ABSTRACTPrevious work on the mineralogy of the volcanic supra‐Wyrley Yard tonstein is extended to include the opaque minerals. This has led to a better understanding of the major and trace element geochemistry of the tonstein. The complete mineral assemblage is kaolinite (dominant) with minor quartz, K‐mica, zircon, apatite, pyrite, sphalerite, galena,

Upper Carboniferous herbaceous lycopsids

Review of Palaeobotany and Palynology, 1997
Abstract Herbaceous lycopsids are often overlooked in palaeobotanical studies because of problems of morphological interpretation and identification. The literature on Euramerican Upper Carboniferous herbaceous lycopsids is reviewed on those species referred to the genera Selaginellites, Lycopodites, Paurodendron, Carinostrobus, Miadesmia ...

Upper Carboniferous sedimentation in Derbyshire

Journal of Sedimentary Research, 1960
Abstract A pattern of sedimentation similar to that suggested for deposition of the Mam Tor sandstones of Derbyshire, England is present at higher Namurian (Carboniferous) horizons. The essential difference is that at the higher level, there is no sharp break between the shales and overlying sandstone; instead a lithologic rhythm is ...

Evidence for an Upper Carboniferous mangrove community

1983
The morphological and paleogeographic evidence suggesting that cordaitean-dominated swamps from the early Westphalian D (= 295 m.y.b.p.) of Iowa grew in salt water swamps is reviewed. Cordaitean trees, Psaronius tree ferns, and Medullosa seed ferns contributed 95% of the peat in coal-ball samples taken from three Iowa mines.

Upper Carboniferous Fossils in America and Europe

Nature, 1935
THE interesting note by Prof. A. E. Trueman in NATURE of June 29, p. 1074, recalls to mind some studies of Upper Carboniferous cockroaches, which I made a number of years ago. The results are fully set forth in Annals and Magazine of Natural History, April 1927, but it is now pertinent to quote (p. 393):

The Upper Carboniferous Rocks of the Stainmore Coalfield

Geological Magazine, 1955
AbstractThe sequence of Upper Carboniferous rocks in the outlier at the western end of Stainmore Pass is described. The Upper Yoredale Series is shown to be separated by an unconformity from the overlying “Millstone Grit” series. The Coal Measures are about 800 feet thick and appear to be unconformable on the “Millstone Grit”.
