A giant Ordovician anomalocaridid
Nature, 2011Anomalocaridids, giant lightly sclerotized invertebrate predators, occur in a number of exceptionally preserved early and middle Cambrian (542-501 million years ago) biotas and have come to symbolize the unfamiliar morphologies displayed by stem organisms in faunas of the Burgess Shale type.

End Ordovician extinctions: A coincidence of causes
Gondwana Research, 2014The 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 discrete pulses, both linked in different ways to an intense but short-lived glaciation at the South Pole.

Abstract Since the publication of the Cambrian and Ordovician correlation charts by the Geological Society (Cowie et al. 1972; Williams et al. 1972) it has become more general practice to include the Tremadoc Series in the Ordovician, and although the precise level at which the base

Abstract A comprehensive review of the current state of research on Kazakh Ordovician litho-, bio- and chronostratigraphy is presented. An Ordovician lithostratigraphic framework applied to eight Kazakh first-order tectonic units is outlined and its correlation with the International Chronostratigraphic Scale is given. Presently used criteria

Abstract A number of new marine invertebrate faunas came into being in Ordovician times, and the generally rather monotonous features of the Cambrian biota were changed. Among the fauna were trilobites, graptolites, articulate brachiopods, nautiloids, and rugose and tabulate corals, which are of great significance in stratigraphical ...
