The onset of the ‘Ordovician Plankton Revolution’ in the late Cambrian

Palaeogeography, Palaeoclimatology, Palaeoecology, 2016
Abstract The ‘Great Ordovician Biodiversification Event’ comprises the rapid diversification of marine organisms during the Ordovician Period. It is now clear that this adaptive radiation started for some organisms already in the Cambrian and continued for others beyond the end of the Ordovician, making the ‘Great Ordovician Biodiversification Event’

Late Ordovician extinctions of bryozoans

Lethaia, 1992
An analysis of the final stratigraphic appearances of byrozoan species and genera, compiled in a world-wide bryozoan data base, revealed three discrete Late Ordovician extinctions. A Late Carddoc (Onnian) extinction was most pronounced on the plates of Baltica and Siberia.

Late Middle Ordovician environmental change and extinction: Harbinger of the Late Ordovician or continuation of Cambrian patterns?

Geology, 1997
Positive excursions in carbon isotope compositions of carbonate (∼ 3‰) and organic carbon (∼ 4‰–6‰) from the late Middle Ordovician (middle Caradocian) of the midcontinent and the eastern United States indicate widespread increases in productivity and rates of organic carbon burial that may have drawn down atmospheric p CO 2 , precipitating global ...
