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.

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.

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 ...

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 ...
