• It was associated with " Lepidodendron ", the scale tree, in the Carboniferous coal swamps.
• "Lepidodendron " likely lived in the wettest parts of the coal swamps that existed during the Carboniferous period.
• They were the roots of coal forest lycopsid trees such as " Sigillaria " and " Lepidodendron ".
• In the Fossil Grove at Victoria Park in Glasgow, Scotland, the stumps of " Lepidodendron " trees are found in their original growth positions.
• Likewise, the trunks of " Lepidodendron " would have been green, unlike modern trees which have scaly, non-photosynthetic brown or gray bark.
• The Witteberg Series has yielded fossil fragments of " Lepidodendron "-like plants and large numbers of the ichnogenus known as " Spirophyton ".
• Likewise, the trunks of " Lepidodendron " s would have been green, unlike modern trees which have scaly, non-photosynthetic brown or gray bark.
• The Lycopodiophyta had their maximum diversity in the Upper Carboniferous, particularly tree-like " Lepidodendron " and " Sigillaria ", that dominated tropical wetlands.
• It was a lycopodiophyte, and is related to the lycopsids, or club-mosses, but even more closely to quillworts, as was its associate " Lepidodendron ".
• The gametophytes of " Isoetes " appear to be similar in this respect to those of the extinct Carboniferous giant arborescent clubmosses, " Lepidodendron " and " Lepidostrobus ".
• Whiteinch is notably home to the Fossil Grove, a site within Victoria Park, Glasgow discovered in 1887 and containing the fossilized stumps of 11 extinct Lepidodendron ( " Giant club moss " ) trees.
• The main representatives of flora in the coal marshes were of the genus " Lepidodendron " and genus " Sigillaria ", tree-like plants, which belong to the plant classification Lycopodiophyta.
• The swamp-loving lycopod trees of the Carboniferous, such as " Lepidodendron " and " Sigillaria ", were progressively replaced in the continental interior by the more advanced seed ferns and early conifers.
• Other organisms found at the Joggins site include members of the calamites family, lepidodendron, sigillaria, ferns, various early amphibian species, numerous fish species ( including evidence of coelacanths ) and a variety of arthropod species.
• Although the living lycophytes are all relatively small and inconspicuous plants, more common in the moist tropics than in temperate regions, during the Carboniferous period tree-like lycophytes ( such as " Lepidodendron " ) formed huge forests that dominated the landscape.
• Quillworts are considered by some to be the last remnant of the fossil tree " Lepidodendron " with which they share some unusual features including the development of both wood and bark, a modified shoot system acting as roots, bipolar growth, and an upright stance.
• The Carboniferous coal swamps of West Virginia were dominated by ground pines of the genus " Lepidodendron " that could reach more than 100 feet in height . " Sigilaria ", however, was the largest tree and could be up to six feet in diameter at the base.
• Mazon Creek flora includes : lycopsids, related to modern club moss, with arborescent forms named " Lepidophloios ", " Sigillaria " and " Lepidodendron ", and herbaceous forms called " Lycopodites " and " Cormophyton "; sphenopsids like " Calamites " a tree-like horsetail relative, with common foliage names of " Annularia " and " Asterophyllites ", and a vine-like form called " Sphenophyllum "; Pteridophyta as marattitalean tree ferns and Filicales and Zygopteridales understory ferns, with common foliage names of " Pecopteris ", " Acitheca " and " Lobatopteris "; pteridosperms, also known as seed ferns, an extinct group of plants that grew both as trees and smaller shrubs, with features like pinnated leaves similar to true ferns, but reproduced by seeds instead of spores; they had common foliage names " Mariopteris ", " Alethopteris ", " Odontopteris ", " Neuropteris ", " Laveineopteris " and " Macroneuropteris "; extinct gymnosperm " Cordaites ", believed to be closely related to and sharing many features with modern conifers.
