The exceptional preservation of plant fossils falls into two categories: whole plant preservation and anatomical detail. Whole plant preservation is controlled primarily by transport and event preservation (, ash falls), whereas anatomical preservation can occur through one of several taphonomic pathways: compressionimpression, silicification, coalball formation, pyritization, and ...
Three methods were used to collect data from the same coalball peels and were compared for data comparability and for relative time efficiency. Altho.

normal coalball samples were relatively depleted in 13C (20 to 23 permil rel. PDB). This evidence indicated that isotopicallyenriched marine, inorganic carbon was an important source of carbonate in faunaltype coal balls and that isotopicallydepleted carbon from plant decomposition was the major source of carbonate in normal coal balls.
Concept of Paloebotany: Palaeobotany or the study of fossil plants,, the plants existed in the past and now are entirely extinct. This is the difficult branch of Botany in respect that the fossil plants are difficult to obtain and they are rather scarce. Whenever the fossil plants are found, they are in parts which are to be coordinated.
In the coal ball described were portions of plants that have hitherto been known from the Carboniferous of America only as impressions; they are Calamites, Sphenophyllum, Bothrodendron, and Lyginopteris. Only transverse sections of the steles of Calamites, Sphenophyllum, and Lyginopteris were found. Belonging to Bothrodendron are transverse sections of a stem tip, a megasporangium and ...

The Upper Pennsylvanian (Conemaugh Group) Duquesne Coal west of Steubenville, Ohio represents a deltaic peataccumulating swamp, and is one of the best known of coal swamp floras. In a few places,
1. Introduction. Coal balls were best defined by Seward (1895, p. 85).. "In the Coal Measures of England, especially in the neighbourhood of Halifax in Yorkshire, and in South Lancashire, the seams of coal occasionally contain calcareous nodules varying in size from a nut to a man's head, and consisting of about 70% of carbonate of calcium and magnesium, and 30% oxide of iron, sulphide of ...
The coal ball floras are dominated by cordaitopsids and lycopsids, with the marattialean fern Psaronius as a common element. This is generally consistent with the known macrofloral assemblages but represents a more restricted range of taxa due to the limited number of known occurrences. ...

Cordaites are extinct coniferophytic shrubs and trees of the Late Paleozoic. They were most prominent in tropical coal swamps existing from the Westphalian AB boundary of Western Europe to the middle Desmoinesian (Westphalian D) of midcontinental United States. Structurally preserved coalball cordaites from Pennsylvanian Euramerican coals were analyzed for whole plant understanding ...

Coal Balls. Because coal balls are accumulations of (degrading) plant material (technically peat), they also are an excellent source of various forms of decaying organisms, including fungi. Numerous fungal remains have been found in coal balls, including hyphae, spores, and various types of reproductive structures.
NORTH AMERICAN COAL BALLS One final cryptic episode of Stopes's work on Carboniferous coal balls relates the discovery of coal balls in North America. That discovery has generally been attributed to Adolf Carl Noé (), who collected coal balls in Illinois and adjacent states, beginning in 1922 (Noé 1923; Morey and Lyons 1995).
A Coal ball is a permineralised life form that is full of calcium, magnesium and occasionally iron sulfide. They generally have a round shape. Coal balls are not made of coal, even though they have the name "coal ball". In 1855, two English scientists, Joseph Dalton Hooker and Edward William Binney, found coal balls in England. Because of that ...
