Sphenophyllum sp. (Fig. 5G)

We only found two specimens of these small stems, partly decorticated but showing well-developed secondary xylem. There is no diagnostic feature allowing a specific identification. This genus extends up to the Early Permian where it has been found preserved as compressions at Autun (Igornay).

FERNS

Ferns, particularly marratialean tree ferns, are the most common element of the flora.
