Early and early Middle Ordovician chitinozoans from the Baldone drill core, central Latvia [PDF]
Early and early Middle Ordovician chitinozoans are relatively poorly known in Baltoscandia, thus the understanding of the early diversification of the group, as well as its biostratigraphic utility, is limited. In this paper, we document the distribution

On future directions of Ordovician chitinozoan research [PDF]
Chitinozoans have been known to science for nearly a century. Due to their biostratigraphic utility, chitinozoans were intensively studied from the 1960s to the 1980s, and they have an important place in Ordovician stratigraphy nowadays, alongside ...

Chitinozoan nomenclature and databases [PDF]
In 1930, Alfred Eisenack suggested the term âchitinozoanâ for a microfossil group that he discovered from erratic boulders on the Baltic Sea coast.

Morphological variation suggests that chitinozoans may be fossils of individual microorganisms rather than metazoan eggs. [PDF]
Chitinozoans are organic-walled microfossils widely recorded in Ordovician to Devonian (ca 485–359 Mya) marine sediments and extensively used in high-resolution biostratigraphy.

Lower Silurian biostratigraphy of the Viirelaid core, western Estonia [PDF]
The distribution of five groups of fossils in the upper Llandovery (Telychian) and Wenlock of the Viirelaid core section, Estonia, is presented and discussed in terms of their biozones (conodonts and chitinozoans) and mutual positions (scolecodonts ...

Latest Sandbian brachiopods and chitinozoan biostratigraphy in North Estonia [PDF]
The latest Sandbian brachiopods and chitinozoans were studied in the Kõrgessaare and Haapsalu drill cores of Estonia. The brachiopod fauna shows a gradual renewal through the Keila Regional Stage (RS), differently from the rather persistent association ...

Chitinozoan biostratigraphy of the Přídolí Series of the East Baltic [PDF]
The succession of chitinozoans in the East Baltic Přídolí Series was studied in the Ohesaare, Ventspils D-3, Pavilosta and Dubovskoye (Northern-Gusevskaya 2) drill cores.

The succession of Hirnantian events based on data from Baltica: brachiopods, chitinozoans, conodonts, and carbon isotopes [PDF]
The Hirnantian (late Ordovician) environment was complex and dynamic. Understanding the correct order of events and their precise correlation with a time scale are extremely important for the development of different kinds of environmental ...

Early–Middle Ordovician chitinozoans from the Dawan Formation, Yichang area, Central China [PDF]
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 chitinozoan assemblage from the Middle Devonian Los Monos Formation (sub-Andean basin, southern Bolivia) and its biozonal implications for Western Gondwana. [PDF]
Chitinozoans recovered from one section of the Middle Devonian Los Monos Formation in the TCB X-1001-Tacobo borehole, sub-Andean basin of Bolivia, have been analysed.
