Journal ArticleDOI
The Ordovician Biodiversification: revolution in the oceanic trophic chain
Thomas Servais,Oliver Lehnert,Jun Li,Gary L. Mullins,Axel Munnecke,Alexander Nützel,Marco Vecoli +6 more
TL;DR: The early Palaeozoic phytoplankton (acritarch) radiation paralleled a long-term increase in sea level between the Early Cambrian and the Late Ordovician as discussed by the authors.
Journal ArticleDOI
Carbon isotope record of Late Cambrian to Early Ordovician carbonates of the Argentine Precordillera
TL;DR: A more than 2000m-thick Cambrian-Ordovician carbonate platform succession developed on the exotic Argentine Precordillera terrane during rifting from Laurentia and drifting towards Gondwana as mentioned in this paper.
Journal ArticleDOI
Did intense volcanism trigger the first Late Ordovician icehouse
Werner Buggisch,Michael M. Joachimski,Oliver Lehnert,Stig M. Bergström,John E. Repetski,Gerald F. Webers +5 more
TL;DR: In this paper, oxygen isotope record in conodont apatite was studied to reconstruct the paleotemperature history during late Sandbian to Katian (Mohawkian-Cincinnatian) time.
Journal ArticleDOI
Palaeoclimate perturbations before the Sheinwoodian glaciation: A trigger for extinctions during the ‘Ireviken Event’
TL;DR: In this paper, the authors studied the oxygen isotope composition of conodonts from the Telychian to Sheinwoodian conodets in the Ozarkodina sagitta rhenana superzone and found that the most severe extinctions and faunal turnover occurred during the early, warmer interval of the event.
Journal ArticleDOI
Origin of planktotrophy--evidence from early molluscs.
TL;DR: It is speculated that an increasing nutrient supply and availability of photoautotrophic plankton in world oceans have facilitated both planktotrophy and suspension feeding, which does not exclude a contemporaneous predation‐driven escalation.
