A modern assessment of Ordovician chitinozoans from the Shelve and Caradoc areas, Shropshire, and their significance for correlation [PDF]

open access: bronze, 2009
New chitinozoan data are presented from the classical section along the Onny River in the type Caradoc area, and from the deeper-water sections in the Shelve area, including the former British candidate GSSP for the base of the Upper Ordovician Series ...

Early–Middle Ordovician chitinozoans from the Dawan Formation, Yichang area, Central China [PDF]

open access: goldJournal of Micropalaeontology
The late Early to early Middle Ordovician is a key interval for chitinozoan macroevolution, during which chitinozoans diversified significantly, reaching their first enormous radiation later in the Darriwilian.

A new Middle Devonian chitinozoan assemblage from northern Iberia [PDF]

open access: hybridReview of Palaeobotany and Palynology, 2019
Chitinozoans were recovered from the Naranco, Huergas and Gustalapiedra formations of northern Spain, which yielded a diverse assemblage including 29 taxa in 9 named genera. The deposits are of early Givetian age, a time when Iberia was isolated from large continents as part of the Armorican Terrane Assemblage.

Chitinozoan diversity in the East Baltic Silurian [PDF]

open access: yesEstonian Journal of Earth Sciences, 2009
Data on the diversity of the East Baltic Silurian chitinozoans have been compared to global chitinozoan biozones that are approximately correlated with the graptolite scale. The total diversity and balanced total diversity curves have three main positive peaks in the Wenlock and Ludlow and diversity lowstands in most of the Llandovery and Pridoli.

Precise chitinozoan dating of Ordovician impact events in Baltoscandia [PDF]

open access: hybridJournal of Micropalaeontology, 1996
Abstract. 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 bentonitic horizons at their top. Chitinozoans, together with graptolites and other planktic
