Why is all coal the same age?

Answer: Large tree-like plants evolved before fungi evolved the ability to break down the fibrous lignin that helped give the plants structure. With nothing to make them decay their remains were free to pile up and yield thick coal deposits.

Is coal an old tree?

“Trees would fall and not decompose back ” write Ward and Kirschvink. Instead trunks and branches would fall on top of each other and the weight of all that heavy wood would eventually compress those trees into peat and then over time into coal.

Coal is very old. The formation of coal spans the geologic ages and is still being formed today just very slowly. Below a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).

Where does coal come from originally?

Vast deposits of coal originate in former wetlands—called coal forests—that covered much of the Earth’s tropical land areas during the late Carboniferous (Pennsylvanian) and Permian times. However many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras.
