Abstract The end Ordovician (Hirnantian) extinction was the first of the five big Phanerozoic
extinction events, and the first that involved metazoan-based communities. It comprised two …

The temporal and spatial distribution of Hirnantian brachiopod faunas are reviewed based
on a new, comprehensive dataset from over 20 palaeoplates and terranes, a revised …

The greatest relative changes in marine biodiversity accumulation occurred during the Early
Paleozoic. The precision of temporal constraints on these changes is crude, hampering our …

The end-Ordovician mass extinction (EOME) is widely interpreted as consisting of two
pulses associated with the onset and demise of the Gondwana glaciation, respectively, with …

Abstract The Ordovician of Scandinavia (ie Denmark, Norway and Sweden) has been
investigated for over two centuries and, through time, various chronostratigraphic schemes …

The phylogeographical evolution and the consequent changing distribution and diversity of
rhynchonelliform brachiopods through the Ordovician are linked to the dynamic …

A recent drilling at Borenshult near Motala resulted in discovery of the stratigraphically most
complete succession through the upper Darriwilian–Rhuddanian interval known in …

Global biodiversity has been punctuated throughout the Phanerozoic by extinction events
that vary in their degree of intensity and devastation. The mass extinction event that occurred …

The Late Ordovician (late Katian) Tcherskidium fauna consisted of large-and thick-shelled
virgianid pentamerid brachiopods characterized by large and ribbed shells of Tcherskidium …

The diversity of several groups of Late Ordovician fossils in the Baltic is discussed and
corresponding curves are presented. The curves are correlated with the latest δ13C trend …
