Callipterid peltasperms of the Dunkard Group, Central Appalachian Basin

DiMichele, William A.; Kerp, Hans; Sirmons, Roberta; Fedorko, Nick; Skema, Viktoras; Blake, Bascombe M., Jr.; Cecil, C. B. (2013)

Abstract The Dunkard Group is the youngest late Paleozoic rock unit in the Central Appalachian Basin. Its age, however, remains controversial. In its southern and western two-thirds the Dunkard is comprised largely of red ...

Moisan, Philippe; Labandeira, Conrad C.; Matushkina, Natalia A.; Wappler, Torsten; Voigt, Sebastian; Kerp, Hans (2012)

Associations between lycopsid and herbivorous arthropods are rare in the fossil record and equally sparse among the three surviving lineages of Lycopodiaceae. Selaginellaceae and Isoetaceae. However, from the Middle Upper ...
