Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight.[1][2] The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or "coal-bearing" Period.[3] As well, there are extensive coal deposits from the Cretaceous age - about 65 to 144 million years ago.[4] (Please see the timeline at the bottom of the page.)
7. Coal and oil: How do they form? - EarthSky

Both coal and oil are fossil fuels. That means they’re formed from organic matter – stuff that was alive on Earth millions of years ago – that was covered by heavy layers of rock. Over time, the increased pressures and heat resulting from the overlying rock transformed the decomposed matter to coal or oil.

The majority of fossils recovered in Cape Breton can be traced to coal areas or coal fields. Fossils have been found ranging from whole or partial tree trunks and branches to shrubs and vine growth. Evolution dates back to pre-historic times – to approximately 325 million years ago when the region was covered in lush, dense vegetation.

12. A marine origin of coal balls in the Midland and Illinois basins, USA

Coal balls are carbonate concretions that preserve peat in cellular detail. Despite their importance to paleobotany, the salinity of coal-ball peat remains controversial. Pennsylvanian coal balls from the Midland and Illinois basins contain echinoderms and early high-magnesium calcite cement. Echinoderm skeletons reflect the Mg/Ca ratio of the seawater in which they grew. Here we show that well-preserved echinoderms in coal balls and North American Pennsylvanian marine facies have similar average mole % MgCO3; 10.2–12.3 and 9.9–12.5 respectively. Coal-ball echinoderms reflect the magnesium content of the adjacent epicontinental seawater. Early high-magnesium calcite cement in coal balls has the same, or more magnesium than echinoderms from the same deposit, and high Sr/Ca and Na/Ca, consistent with formation in marine or brackish water. Subsequent coal-ball cement is low-magnesium calcite, suggesting freshwater diagenesis and cementation followed formation of marine high-magnesium calcite. Coal balls likely formed in the marine-freshwater mixing zone. Remnants of marine echinoderm skeletons included in Pennsylvanian coal balls from the Midland and Illinois basins, USA, contain Mg/Ca ratios indicative of marine facies, according to geochemical analysis
