Eggert, 1969), only two coalball occurrences from the Appalachian Basin are noted in the literature (Schopf, 1961; Cross, 1967). To our knowledge, no coalball occurrence have been reported in the state of Ohio, but recent inquiries have
Department of Botany, Ohio University, Athens, Ohio 45701 Basal parts of Botryopterisforensis have been discovered rooted within the mantle of the tree fern Psaronius. Specimens occur in Upper Pennsylvanian coal balls from near Steubenville, Ohio, USA. The Botryopteris stems branch profusely, and these shoots are intertwined with the
InstruZetor, Henry Shaw School of Botany of Washington University The occurrence in America of the petrifactions known as coalballs has been known for many years and in itself needs no review. It is, however, still rather generally accepted that American coalballs are by no means the equal of the renowned English specimens

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 ...
Many collecting trips to coal mines, searching for "coal balls," limestone masses densely packed with anatomically preserved plant fossils, resulted in the largest coal ball collection in the ...
Three methods were used to collect data from the same coalball peels and were compared for data comparability and for relative time efficiency. Altho.

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.
Abstract. Pachytesta stewartii, a new species found in Middle Pennsylvanian coal ball deposits in southern Illinois, is cm long and approximately cm in width at its greatest diameter. Commissured ribs are pronounced near the apex and progressively less distinct toward the base. The integumentary system is delimited into 3 regions: outer ...
In this activity, students learn about ancient plant life and climate change by examining coal balls. In addition to the lesson itself, information is provided on where to purchase coal ball peel kits for handson experience.
The physical and digital curation of cellulose acetate peels and other types of coal ball specimens is critical for longterm preservation and accessibility. Physical curation involves embedding coal balls in media to slow pyrite deterioration. Digital curation creates highresolution scans of peels, which can be shared and accessed online.
A coal ball is a type of concretion, varying in shape from an imperfect sphere to a flatlying, irregular balls were formed in Carboniferous Period swamps and mires, when peat was prevented from being turned into coal by the high amount of calcite surrounding the peat; the calcite caused it to be turned into stone instead. As such, despite not actually being made of coal, the coal ...
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 ...
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 ...
Acetate paper with a thickness of inches is used to make the first peel of a coal ball after it has been cut with a rock saw. This paper type can also be used for test peels to identify the optimum etching time in acid. The .005inchthick acetate paper is more robust, reducing the chance of damage when removed.

6. Coal Balls: Petrifactions of spherical specimens are generally termed coal balls. During the formation of coal balls the plant material in swamps gets infiltrated with carbonates of calcium or magnesium, so that the debris of plants will not get converted into coal. Coal ball plants are of great value in palaeobotanical studies. 7.

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 ...
