.... The vegetation was dominated by monospecific stands of the arborescent lycopsid Sigillaria brardii , whereas the tree fern Psaronius occurred during the later stages of mire accretion. This is in contrast to coeval North American peat mires, which generally were dominated by tree ferns and pteridosperms...
