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.

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 ...

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 ...

Edward William Binney, the first investigator of the Lancashire coalballs, was born at Morton in Nottinghamshire in 1812, and was thus only four years senior to Williamson. He settled in Manchester in 1836, and practised as a solicitor. He early showed scientific tastes; the Manchester Geological Society was started, chiefly by his influence ...
