 * I'd prefer it if the refs for "In situ theory" are moved to the end of the paragraphs, and that File:Zeche Billigkeit 5.jpg is added . --Sp33dyphil ©hatontributions 07:33, 22 January 2012 (UTC)
 * If I put the refs for "In situ theory" at the end of the paragraph, then readers might think that it only supports Over the course of many years, temperature increased, and the peat was slowly converted into coal. Placing it at the end of In the in situ theory,[2] I assumed that the reference would be interpreted as supporting the whole paragraph. → Σ  τ  c . 08:17, 22 January 2012 (UTC)
 * But since the paragraph's sentences link up with each other through conjunctions, the read will think that the ref is for the whole para. --Sp33dyphil ©hatontributions 08:37, 22 January 2012 (UTC)

Article has serious issues, starting with the first sentence ("The formation of coal took place approximately 300 million years ago, during the Carboniferous Period"). In fact, there's a lot of coal formed in other geologic periods -- for example, see this page (on that page "Carboniferous" corresponds to the Mississippian and Pennsylvanian Periods). Overall, the sourcing is inappropriate for an article about a scientific topic, with heavy reliance on 19th century publications. The newer publications are about coal balls, not coal in general. --Orlady (talk) 23:14, 28 January 2012 (UTC)
