Giant cladoxylopsid trees resolve the enigma of the Earth's earliest forest stumps at Gilboa

Article Abstract:

An intact crown belonging to the cladoxylopsid Wattieza (Pseudisporochnales) and its attachment to Eospermatopteris trunk and base has allowed the reconstruction of a tall, tree-fern-like plant with a trunk bearing large branches in longitudinal ranks. They produced abundant litter, indicating the potential for terrestrial carbon accumulation and detritus-based arthropod fauna by Middle Devonian period.
