New palaeogeographical reconstructions for the earlier Ordovician (480 Ma), and later
Ordovician (450 Ma) integrate revised longitude-calibrated palaeomagnetic reconstructions …

The early Paleozoic sediments document two major biological events: the Great Ordovician
Biodiversification Event (GOBE) and Late Ordovician mass extinction (LOME). Many …

Abstract The Cambrian 'Explosion', located by many authors between 540 and 520 million
years ago (Ma), is considered to be an abrupt appearance in the fossil record of most animal …

The Ordovician biodiversification is considered one of the most significant radiations in the
marine ecosystems of the entire Phanerozoic. Originally recognized as the 'Ordovician …

Abstract The Ordovician Radiation shaped Paleozoic marine ecosystems and led to an
increase in the biodiversity of marine organisms. The onset of the Plankton Revolution in the …

Marine biodiversity increased markedly during the Ordovician Period (~ 487–443 million
years ago). Some intervals within the Ordovician were associated with unusually rapid and …

Marine red beds (MRBs) are often attributed to specific redox environments during
syndepositional and early diagenetic phases. During the Middle Ordovician, a succession of …

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

Diversification is a key property of life. Building on John Phillips'(1860) classic, iconic curve,
Phanerozoic biodiversity trajectories have been based, subsequently, on the availability of …

A review of biodiversity curves of marine organisms indicates that, despite fluctuations in
amplitude (some large), a large-scale, long-term radiation of life took place during the early …
