A photograph of a cellulose acetate peel showing the fossil peat preserved in a coal ball. Palynology. Millions of years ago, in the interval of geologic time called the Pennsylvanian, the presentday coal seams of the Midwest were layers of peatbeds of water soaked and somewhat rotted plant debris accumulated in thickly forested swamps ...
Coal ball peel of Anachoropteris involuta from the Upper Pennsylvanian of Illinois, Forschungsstelle für Paläobotanik Münster. Making coal ball peels is an easy method for studying anatomically preserved plant remains in coal balls. Further details are given by Prof. Rothwell on his
the cellulose acetate peel method and coal ball curation. We also introduce a new protocol for the digitization and curation of peels, which is in use at the Phillips Coal Ball Collection at the University of Illinois Urbana‐Champaign. In documenting these protocols, we hope to establish a standardized procedure for working with coal balls.

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 ...
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.
Coal ball. 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.

DRAW some of the cellular material you discovered in your coal ball peel in the space below: 2. The plant cells you have observed are present in a coal ball that formed at the same time as the coal seam from whence it came; that would make these cells approximately 380my years old. 3. These cells are from which geological period? Carbon ephorus

Anthracite Coal (Hard Coal) Anthracite coal is the highest grade of coal. Anthracite is dark black, very shiny and has a glass like consistency. In the United States the primary source is Northeastern Pennsylvania. It has an average BTU content of 24 to 25 million per ton but can exceed 28 million for the highest quality anthracites.
