Dispersed conducting tissue from the Gzhelian (Saberian) of the Kounov Coal in the Kladno-Rakovník Basin, Czech Republic
Main Article Content
Abstract
The late Pennsylvanian Kounov coal seam yielded exceptionally well-preserved vascular elements. Their determination is questionable due to their fragmentary nature. Scalariform, reticulated and pitted tracheids prevail. They are comparable with the sphenopsid plants Arthropitys and Sphenophyllum. Some scalariform and reticulated tracheids also resemble those of ferns. However, their precise determination is not possible. Some uniseriate pitted tracheids resemble some conifers. Because conifers do not occur in coal, they might belong to secondary wood of some calamitaleans. Dispersed vascular tissues are correlated with dispersed cuticles and macrofossils.
