I believe it was during the Permian and Pennsylvanian eras.
Coal begins to form in a humid and warm climate where organic matter, such as dead plants, accumulates in oxygen-poor environments like swamps and wetlands. Over time, the organic matter gets buried and undergoes transformation into peat, then lignite, and finally coal through a process known as coalification.
Carbon in coal is oxidized to form carbon dioxide gas when coal is burned.

it can be sedimentary rocks
Lignite is a form of soft, brownish-colored coal that is often referred to as brown coal. It is one of the lower-ranked types of coal in terms of carbon content and energy output.
Coal is a form of rock. It is an organically formed sedimentary rock.
