| Popis: |
Petrified stems (rhizomes) of a fern are described from Late Cretaceous (Cenomanian) beds in Bahariya Oasis. The discovered stems are related to Paradoxopteris stromeri Hirmer (fern rachii) and to Weichselia reticulata Stokes & Webb. (fern pinnae); both already known from also Cenomanian beds of this Oasis. Haloed axes are described from Late Cretaceous (Campanian) beds, i.e. younger than the beds containing the petrified stems. Comments on the nature of these axes, the affinities of the stems and the palaeoenvironments of the area in the two mentioned geologic ages (Cenomanian & Campanian) are given. |
