State
During the Carboniferous period, forests of giant lycophytes and horsetails accumulated as undecomposed plant matter, later compressed over geologic time into coal.
Show
Today's coal seams trace their carbon to that ancient seedless-vascular-plant biomass, buried before decomposition could break it down.
Watch for
This period's plant dominance predates seed plants — the giant lycophytes forming these forests were seedless vascular plants, not gymnosperms.
