Palynological samples from two boreholes drilled in the eastern part of Saudi Arabia contain a rich assemblage of cryptospores and trilete spores. They are dated as most probably Lochkovian in age. Intriguingly, the cryptospores are very similar to those from a coeval continental palynomorph assemblage from the Old Red Sandstone Continent, whereas the trilete spores show a strong affinity with miospore assemblages from Western Gondwana. It is suggested that cryptospore-producing plants inhabited confined, damp biotopes and had a wide range of climatic tolerance. On the otherhand, trilete spore-producing plants inhabited a wider variety of biotopes but were more sensitive to climatic variations. The high degree of similarity between Old Red Sandstone and Saudi Arabian cryptospore assemblages favours palaeogeographic reconstructions where there is close proximity between Western Gondwana and Euramerica and/or a land connection between these palaeoplates. Climatic differences between the Old Red Sandstone Continent and the northern part of Western Gondwana can be invoked to explain the variations in the trilete spore assemblages.

New terrestrial and marine palynomorphs of the lower part of the Villavicencio Formation, San Isidro Creek, Precordillera of Mendoza, Argentina, are evaluated. The palynomorph assemblage is dominated by miospores, and also contains acritarchs and scarce chitinozoans. Different processing methods have been tested due to the poor preservation state of the palynomorphs. The new slides provided abundant and diverse palynomorphs and allowed the recognition of 13 miospore species and two acritarch species. This review suggests a late Pragian to early Emsian age, thus confirming and refining previous palynological dating. The miospore assemblage may be correlated with the upper part of the Ems Biozone in terms of the Devonian miospore zonation of the Brazilian Amazon Basin. Palaeogeographically; acritarchs show perigondwanan affinities. In the light of this refined age determination, the stratigraphic and phytogeographic inferences for the Precordillera land plants should be reconsidered. [less ▲]

Preliminary results are presented on newly discovered megaspore assemblages recovered from Givetian localities at Ronquières, Belgium, and a borehole (A1-69) drilled in the Ghadames Basin, Libya, by SHELL in 1959. The miospore biostratigraphy of the Ronquières and of A1-69 borehole sections has been published (Ville de Goyet, 2005; Gerrienne et alii, 2004; Loboziak & Streel, 1989; Loboziak et alii, 1992; Streel et alii, 1990).
