TL;DR: Palynological and palynofacies analyses combined with organic carbon isotope measurements have been performed on terminal Ordovician through Silurian clastic sediments from the North African margin of Gondwana (southern Tunisia) as discussed by the authors.

TL;DR: In this paper, cryptospores and trilete spores from North Africa (MG-1 borehole, Ghadamis Basin, southern Tunisia) were used to contribute to the understanding of the terrestrialization process, its timing and its palaeoenvironmental consequences across the Silurian-Devonian transition in Western Gondwana.

TL;DR: Morphological/ultrastructural studies confirm the lycopsid affinities of this megaspore and it is suggested that it probably derived from an arborescent lycopid that belonged with the Lepidocarpaceae that went on to dominate the Euramerican Coal Measure forests.
