The clubmosses

We have not found any fossils worth mentioning of the clubmoss tree Lepidodendron. The clubmoss trees were in fact declining during the Stephanian.

Sigillaria
We found slightly more fossils of Sigillaria, mainly on the left hand side of the brook near the Découverte de l'Hérault, the quarry last abandoned. It seems that most of the Sigillaria fossils are found directly above the coal seams. Sigillaria brardii
SyringodendronSigillaria brardii is the most common species. The leaf scars of the younger trunks form a rhombic pattern and the otherwise characteristic vertical ridges are missing. In older trunks the leaf scars are remote. Click on the photo on the left.

When the outer bark has disappeared, a trunk with vertical grooves remains, with pairs of scars sitting in between (like footprints of a hare) which come from air channels in the trunks. The kind of preservation is called Syringodendron (click on the photo on the right). When the bark has disappeared still more and only the ridges remain.

We have not seen any spore cones nor branches with leaves of clubmosses.
