Overview of the warehouse collection of coalball peels assembled by Tom Phillips and students. Dr. Phillips, as he was ever known to most of his students, turned his attention almost exclusively to research on Pennsylvanianage plants, anatomically preserved in coalballs, starting in the early 1970s.

COAL BALL PEEL TECHNIQUE. Coal balls are spherical to ellipsoidal masses of calcium carbonate (or calcium magnesium carbonate) in which plant tissues are tree dimensionally preserved, embedded within the carbonate matrix. The carbonate essentially impregnates the residues of the plant cell walls and fills the cell cavities. Concentration of the carbonate occurred by localized precipitation ...

The evaluation of organic material in the coal balls was based on peel studies from 50 randomly selected coal balls from all areas of the crop. Each coal ball regardless of size was considered as one unit. From many of the coal balls numerous peels were obtained but only 2 peels oriented normally to each other were evaluated from each concretion.
