A coal ball is a type of concretion, varying in shape from an imperfect sphere to a flatlying, irregular slab. Coal balls were formed in Carboniferous Period swamps and mires, when peat was prevented from being turned into coal by the high amount of calcite surrounding the peat; the calcite caused it to be turned into stone instead.

Stratigraphic studies of coal ball plants and spores have indicated major vegetation changes of coalball floras through the Upper Carboniferous. Extinctions of plants have been linked to distinctive climatic changes, in particular decreasing rainfall which affected the more wetloving plants (DiMichele and Phillips, 1994).
