The Phillips Coal Ball Collection is the largest and most significant collection of coal balls in the world. It contains almost 50,000 intact specimens and a quarter of a million "peels"—extremely thin layers (less than a cell thick) peeled from a coal ball slice. Further, the collection represents 80 different coal seams that together ...
Upon drying the acetate film was removed (peeled—hence the reference to the "peel technique") to provide a thin section of the coalball plant material. A 1 cm 2 grid of clear cellulose acetate was attached to each coalball peel. Within each square centimeter, the most common plant part and its taxonomic affinity were identified and ...

Middle: amount of total peel shrinkage (initial peel size minus peel size after 7 ...
This embeds the cells preserved in the coal ball into the cellulose acetate. Upon drying, the cellulose acetate can be removed from the coal ball with a razor and the obtained peel can be stained with a lowacidity stain and observed under a microscope. Up to 50 peels can be extracted from 2 millimetres ( in) of coal ball with this method.
These "peels" are studied closely by scientists. It's a process that Tom Phillips created and others have developed. To date, U of I researchers throughout the decades have created more than 250,000 coal ball peels. Part of Lakeram's work is digitizing highmagnification images of them. "The point of digitizing the peels is (to ...

Detail of a socalled coal ball peel: a cross section of the anatomically preserved plant tissues inside a single coal ball from the Herrin Coal, Peabody Eagle Surface Mine Number 2, Shawneetown, Illinois. Age upper Middle Pennsylvanian. A thin layer of plant material is embedded in a transparent acetate sheet, or peel.

Baxter's list (Baxter, 1960) of coalball plants from New Brunswick is updated and these fossil plants are illustrated here for the first time on the basis of an examination of his peels. The palynomorphs and coalball plants of the Foord seam of the Stellarton Basin are illustrated and their paleoecology is discussed.
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.
The Tommy L. Phillips coal ball collection at the University of Illinois contains a voluminous quantity of Carboniferous coal balls (permineralized peat) and coal ball peels from around the world, with the bulk hailing from the Illinois Basin. Contained in the collection are a variety of sample sets and maps, including 'vertical sections' where ...

During more than four decades, about 800,000 cm2 of coal ball peels have been microscopically investigated. For each cm2, plant taxa, plant organs, and tissue types have been identified and enumerated. In unparalleled detail, these data provide information on the (aut)ecology and evolution of the autogenic ecosystem engineers that formed the ...
Making a coalball peel. Step 1: After the coal ball has been sawed, it must be ground perfectly flat. A small amount of number 400 silicon carbide grit is used on a sheet of plate glass. Step 2: The grit is moistened to a soupy consistency, and the coal ball is ground for several minutes with a rotating motion. It is then washed thoroughly.

When acetate peels are prepared from cut coalball slices, dissolved acetate infiltrates microvoids created by acid etching. When a peel is lifted from a coal ball slice, coalified plant remains are wellembedded in the dried acetate film. Coalball carbonate minerals are partially embedded in a similar manner, in particular, the fibrous ...
