Miospores, megaspores and Lepidopteris ottonis (Goeppert) Schimper in the uppermost Triassic deposits from Poland

Abstract

This article presents stratigraphic position of the deposits, containing the remains of the leaf of the seed fern Lepidopteris ottonis (Goeppert) Schimper. The opinion is that the range of this species comprises two miospore zones: Corollina meyeriana and Ricciisporites tuberculatus and one megaspore assemblage Trileites pinguis. In the profiles from Poland these zones document the epicontinental “Rhaetic” deposits, which - according to the chronostratigraphic scheme - belong to the Alpine stages: the Norian and Rhaetian.
