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.

Permineralized plant fossils (coal balls) of Bolsovian age (ex Westphalian C) were discovered in the Foord seam of the Stellarton Basin of Nova Scotia. The coalball plants were preserved in a sideritedolomite matrix and formed in a nonmarine intermontane setting. The coalball flora is dominated by arborescent lycopods and contains a few ferns, as well as occasional seed ferns, calamiteans ...

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 ...

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.

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 ...
