    Is Archaeopteris the same as Callixylon?
    In the 1960s, paleontologist Charles B. Beck was able to demonstrate that the fossil wood known as Callixylon and the leaves known as Archaeopteris were actually part of the same plant. It was a plant with a mixture of characteristics not seen in any living plant, a link between true gymnosperms and ferns.

    What did Archaeopteris do in the Devonian era?
    Looking roughly like a top-heavy Christmas tree, Archaeopteris may have played a part in the transformation of Earth's climate during the Devonian before becoming extinct within a short period of time at the beginning of the Carboniferous period. ^ Beck, CB (1960). "The identity of Archaeopteris and Callixylon".

    Archaeopteris är ett utdött ormbunkssläkte från yngre Devon. Archaeopteris hade dubbelt parbladiga blad, rundade eller stipelliknande bihangsblad vid basen av stjälken.. Släktet har troligen tillhört fröormbunkarna.Ståtliga exemplar av archaeopteris med upp till meterlånga blad är kända från Irland och bland fossil i arktiska trakter som på Björnön.
