Microfloristic Evidence on the boundary between the Carboniferous and the Permian systems in Pfalz (W. Gwemany)

Abstract

The Sporae dispersae recovered out of the coals from the Upper Carboniferous (Stephanian C)- Lower Rotliegend succession in pfalz (W. Germany), assigned to 17 spore genera, have been described. It includes an account of four new species of Sporae dispersae. It has been discovered that Lycospora disappears at the end of Stephanian C and Triquitrites continues to remain absent in Kuseler Schichen even. The succeeding microflora in Kuseler Schichten (Lower Rotliegend) continues as a much depleted Stephanian C microflora till finally dying out in Upper Kuseler Schichten. It has been concluded that microfloristically Kuseler Schichten can form a part of the Carboniferous and the boundary between the Permian and the Carboniferous can preferably lie between Kuseler Schichten and the succeeding Lebacher Schichten.
