Chitinozoan Biodiversity in the Ordovician of Gondwana: An Interval-Free Approach Using the Quantitative Stratigraphic Correlation Program CONOP9 [PDF]
, 2015 The purpose of this study is to examine the biodiversity patterns of a group of fossil organisms called chitinozoans. Chitinozoans are organic-walled, planktonic microfossils that first appear in the Early Ordovician Period (488 million years ago) and ...

Precise chitinozoan dating of Ordovician impact events in Baltoscandia
, 1996 . The chitinozoan biostratigraphy of four Ordovician impact craters has been investigated. Three of these (Tvären, Kärdla and Lockne) contain complete sequences of early Caradoc age, while the Granby crater contains rocks of late Arenig age yielding two ...
