Two plant like fossil are described from the middle Ordovician of the pragu
e Basin, Czech Republic. Both fossils bear a strong superficial resemblance
to early land plants, but anatomical data indicate an affinity with animal
s. New evidence on internal structure demonstrates that the putative: plant
Boiophyton pragense Obrhel is a dendroid graptolite. The relationships of
other heavily coalified, branched axes found in associated strata are more
obscure. Scanning electron microscopy of surface features suggests that the
se plant-like remains are fossils of the collagenous stipes of gorgonacean
octocorals.
