set: fossils // series: coal // picture: LEPIDODENDRIDS
This Upper Carboniferous (315 million years) tree is preserved as a sediment infill the in place it grew in a low lying swamp forest where peat was deposited. Upon burial the peat was converted to coal. Such coal has been extensively mined and used for the generation of electricity. Coal also powered the industrial revolution. This tree belongs to an extinct group of plants, tree-sized club mosses (lepidodendrids) which were widespread in tropical equatorial regions in the Carboniferous.
