Rue/1542 "Psaronius porosus", collection HEINRICH COTTA, Ruedigsdorf site, Museum fuer Naturkunde Berlin

Fragment of a tree fern root mantle. It is difficult to relate
the sample to a location.
It could have come from Ruedigsdorf as well as from the Nova Paka region in
the
Czech Republic. Unfortunately there are no recently found Psaronius samples
from Ruedigsdorf for comparison.
