No, most coal comes from plants in swamps, because the water helped preserve the organic matter.
Plants in swamps die -> organic matter on the bottom of the swamp -> peat -> brown coal -> black coal.
Oil apparently comes mostly from plankton.

Oil was effectively plankton and other sea stuff.
Coal was forests.

Brother I finally found you.
We come from the same place you and me. Remember that barn?
