“…An analogous situation has been recently reported of a frond fragment from the upper Westphalian of the Zwickau Coalfield (Germany) that superficially resembles Lobatopteris but which appears to have ovules attached (Krings & Schultka, ). Although Wagner () diagnosed Lobatopteris exclusively on morphological characters of the pinnules, he clearly regarded it as a (fossil‐)genus of marattialean fronds (see also Cleal, ; Wittry et al, ). The presence of attached ovules therefore makes its systematic position in Lobatopteris problematic.…”

“…It is possible that this was due to a Lazarus effect (sensu Flessa & Jablonski, 1983 (Krings & Schultka, 2010). Although Wagner (1959b) diagnosed Lobatopteris exclusively on morphological characters of the pinnules, he clearly regarded it as a (fossil-)genus of marattialean fronds (see also Cleal, 2015;Wittry et al, 2014). The presence of attached ovules therefore makes its systematic position in Lobatopteris problematic.…”

“…All material described here consists of sterile specimens, and the largest specimen (holotype UP‐MHNFCP‐154066; Figures a and a) represents a penultimate order pinna, with lobate to pinnately lobed (pinnatifid) pinnules tapering gradually to smaller and non‐lobed or entire margined pinnules. They show a superficial similarity to certain fern fronds with pinnatifid pinnules, especially Lobatopteris sensu Wagner, , Crenulopteris sensu Wittry, Glasspool, Béthoux, Koll, & Cleal, , and Pecopteris sensu Brongniart, . However, the veining of these ferns tends to have a much more regular, programmed pattern of forking (Cleal & Thomas, , p. 138) such that their branching pattern has proved to be an important generic character (e.g., Pšenička, Bek, Cleal, Wittry, & Zodrow, ; Wagner, , ; Wittry et al, ).…”

In Douro fossils, the veins fork such that the lamina has a relatively even coverage of veins rather than following a preprogrammed pattern, and this is more a characteristic of seed‐plant foliage such in the Medullosales.…”

A new plant fossil‐genus, Douropteris alvarezii gen. nov., sp. nov., is described from the Douro Basin (lower Stephanian C [lower Gzhelian], Upper Pennsylvanian) in north‐western Portugal. Douropteris alvarezii has a remarkable morphology characterized by an unusual combination of features seen in several different fossil‐genera belonging to ferns and pteridosperms. Its unique and distinguishing features place it nearest to the medullosalean pteridosperms Margaritopteris and Callipteridium, suggesting close affinities with the fossil‐family Cyclopteridaceae. Morphologically, Margaritopteris is the closest relative with basis on the strong resemblance to the veining pattern of Douropteris gen. nov. Here, Douropteris represents a potential “Lazarus taxon” or evolutionary descendant from the Margaritopteris lineage.

“…Wagner, 1958-Crenulopteris Wittry et al, 2014 Four slab faces contain small and poorly preserved fragments of a fern of the Lobatopteris -Crenulopteris complex (cf. Wittry et al, 2014). The terminal (Plate I,3) and more proximal (Plate I, 2) part of a single pinna are illustrated, as is a lobate pinnule (or distal ultimate pinna) of another specimen (Plate I,8).…”

A Middle Pennsylvanian macrofloral assemblage from below the Rock Island (No. 1) Coal Member, Illinois: Resolving the Bolsovian–Asturian boundary in the Illinois Basin

A taxonomic, quantitative, and biostratigraphic analysis is presented for a macrofloral assemblage collected from below the Rock Island (No. 1) Coal Member at the historical Friendship Farm locality in Rock Island County, on the northwestern margin of the Illinois Basin. The Middle Pennsylvanian (middle Moscovian) fossiliferous strata involve the middle Tradewater Formation, and are situated a short distance below the Atokan-Desmoinesian Stage boundary as defined by marine microfossils and palynology. The assemblage of 14 fossil-taxa is overwhelmingly dominated by pteridosperms, including Laveineopteris rarinervis, Neuropteris flexuosa, Alethopteris serlii, Macroneuropteris scheuchzeri, and Mariopteris nervosa, whereas lycopsids, sphenopsids, and ferns are comparatively rare. Homotaxial comparison with the macrofloral biozonation scheme established in Europe indicates an Asturian age for the assemblage, in all likelihood early Asturian (Linopteris obliqua Biozone). Similar comparisons with range limits documented in the Appalachian Basin yield a more ambiguous age, but an early Asturian age is equally probable. These findings indicate that the Bolsovian-Asturian Substage boundary of western Europe lies below the Atokan-Desmoinesian Stage boundary in the Illinois Basin, boundaries that have traditionally been correlated by palynology. The Middle Pennsylvanian interval near these boundaries is being increasingly recognized as one of significant environmental change, reflected in marked lithological and biological modifications throughout tropical Euramerica. However, the fact that the Bolsovian-Asturian and Atokan-Desmoinesian boundaries are not synchronous, albeit being broadly equivalent, suggests that the environmental perturbation was a protracted event that may have had global consequences.
