“…Unfortunately, as will be discussed below, the disposition of the field notebooks associated with these collections is not known, forcing us to rely on secondary sources to assess the stratigraphic interval covered by the collections. The fossil assemblages compare most closely with those described from the Pennsylvanian-Permian boundary elsewhere in Euramerica, including the Dunkard of the U.S. Appalachian Basin (Blake and Gillespie, 2011), Rotliegend of Germany (e.g., Potonié, 1893;Barthel, 1976Barthel, , 2009Kerp and Fichter, 1985;Barthel and Brauner, 2015), the Autunian of France (e.g., Zeiller, 1890Zeiller, , 1892Zeiller, , 1898Zeiller, , 1906Doubinger, 1956;Broutin, 1995, 2008;Steyer et al, 2000;Bercovici and Broutin, 2008), and other European strata that encompass the Pennsylvanian-Permian transition (e.g., Broutin, 1981;van Amerom et al, 1993;Wagner and Martínez García, 1982;Popa, 1999;Šimůnek and Martínek, 2009). …”
