pecopteris

Clement seemed to prefer collecting tree trunk and woody material of Lepidodendron, Sigillaria, Stigmaria, and Calamites, over leafy material as only three specimens of leaves (Pecopteris and Neuropteris) occur in the collection.

Non-medullosans are rare and comprise Calamites sp., Annularia sp., Asteropkyllites equisetiformis, Paleostackya sp., Sphenophyllum oblongifolium, and Pecopteris sp.

Of the four remaining taxa, Ernestiodendron filiciforme occurs in the Early Permian, Usclas-Saint Privat Formation, of the same Basin whilst Pecopteris cyathea is a species both common in the Late Pennsylvanian and in the Rotliegend of Germany (Holotype from Manebach).

The equatorial flora that existed in the watery environments of the Carboniferous Period, for example, included Pteridosperms (Pecopteris, Neuropteris, etc.) with their broad, serrated leaves like those of ferns, but capable of producing seeds.

Some of the siderite nodules have preserved floral elements (Pecopteris unita, calamites stems), as are known from the famous Mazon-Creek Flora of Illinois, U.S.A.

of Autunian affinities, but also contains forms like Sphenophyllum angustiformis, Odontopteris obtusa, Pecopteris densifolia and Calamites suckowi of late Stephanian (Latest Carboniferous) affinities.
