Middle-upper devonian miospores from the Ghadamis Basin (Tunisia-Libya): Systematics and stratigraphy [PDF]
Review of Palaeobotany and Palynology, 1989 Abstract Fifty-five miospores (including 7 new species and 3 new combinations) that range from Emsian to late Frasnian are identified, and 48 illustrated from 4 boreholes in the Ghadamis Basin. Their stratigraphic distribution is given and correlations made with established chronostratigraphic schemes.

The Middle-Upper Devonian Sandstones of the West Magnitogorsk Zone of the Southern Urals [PDF]
Uchenye Zapiski Kazanskogo Universiteta. Seriya Estestvennye Nauki, 2021 To date, the composition of the Devonian sandstones of the West Magnitogorsk zone has been known from only a few samples. However, given the large thickness of the sections (up to the first kilometers), their number should be increased, up to several tens for every formation in each section.
