The most ancient macroscopic plants fossils are early Silurian cooksonioid sporophytes 19 from the volcanic islands of the peri-Gondwanan palaeoregion (the Barrandian area, Prague Basin, 20 Czech Republic). However, available palynological, phylogenetic and geological evidence indicates 21 that the history of plant terrestrialization is much longer...
Article
The end-Ordovician mass extinction, linked to a major glaciation, led to deep changes in Hirnantian–Rhuddanian biotas. The Hirnantia Fauna, the first of two Hirnantian survival brachiopod-dominated communities, characterizes the lower–mid Hirnantian deposits globally, and its distribution is essential to understand how the extinction took place. In...

The colonization of land by vascular plants is an extremely important phase in Earth’s life history. This key evolutionary process is thought to have begun during the Middle Cambrian1 period and culminated in the Silurian/Early Devonian period (interval about 509–393 million years ago (Ma)), and is documented primarily by microfossils (that is, by...
Article
The current Global Stratotype Section and Point (GSSP) for the Aeronian Stage (Llandovery Series, Silurian System), on Trefawr track in the Llandovery area of Wales, is an inadequate marker for precise, global, correlation. The International Subcommission on Silurian Stratigraphy has, therefore, undertaken the selection of a new GSSP for this level...
Article
Full-text available
Significance Climate change during Late Ordovician mass extinction drove an ecologically selective decline in the abundance of deep-water macrozooplankton, accompanied by a shift to simpler, less even communities. These results indicate that the species abundance structure of planktic communities may be a leading indicator of the effects of climate...

Following the melting of the Gondwanan icecap and the resulting postglacial sealevel rise, organic-rich shales were deposited in shelfal palaeo-depressions across North Africa and Arabia during the latest Ordovician to earliest Silurian. The unit is absent on palaeohighs that were flooded only later when the anoxic event had already ended. The regi...
Article
The Hirnantian and Llandovery sedimentary succession of the Barrandian area has been assigned to middle and outer clastic-shelf depositional settings, respectively. Deposition was influenced by the remote Gondwanan glaciation and subsequent, long-persisting, post-glacial anoxia triggered by a current-driven upwelling system. High-resolution graptol...
Article
Following the Latest Ordovician glaciation, black, graptolitic, organic-rich shales were deposited in many places across northern Gondwana that form important hydrocarbon source rocks in the region. Armstrong et al. (2005) presented a study of black shales of this episode from southern Jordan and propose biostratigraphic, sequence stratigraphic and...
