Latest Sandbian brachiopods and chitinozoan biostratigraphy in North Estonia [PDF]
Estonian Journal of Earth Sciences, 2023 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 of chitinozoans. An exception is the uppermost part of the stage, which differs in two sections in

The succession of Hirnantian events based on data from Baltica: brachiopods, chitinozoans, conodonts, and carbon isotopes [PDF]
Estonian Journal of Earth Sciences, 2008 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 ...

On future directions of Ordovician chitinozoan research [PDF]
Estonian Journal of Earth Sciences, 2023 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 graptolites and conodonts.

Chitinozoan nomenclature and databases [PDF]
Estonian Journal of Earth Sciences, 2023 In 1930, Alfred Eisenack suggested the term âchitinozoanâ for a microfossil group that he discovered from erratic boulders on the Baltic Sea coast. They are known from the Early Ordovician until the end of the Devonian and have a broad paleogeographic distribution in marine deposits.

LOWER TO MIDDLE ORDOVICIAN ACRITARCHS AND CHITINOZOANS FROM NORTHERN KARAKORUM MOUNTAINS, PAKISTAN
Rivista Italiana di Paleontologia e Stratigrafia, 2000 The lower Vidiakot section (Chitral, Pakistan) comprises the lower part (Yarkhun Formation and the base of the Vidiakot Formation) of the terrigenous complex transgressively overlying the crystalline basement of Northern Karakorum. From this section, 8 of 15 samples contain moderately abundant and poorly preserved acritarchs and rare, badly preserved ...

Early and early Middle Ordovician chitinozoans from the Baldone drill core, central Latvia [PDF]
Estonian Journal of Earth Sciences, 2022 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

Lower Silurian biostratigraphy of the Viirelaid core, western Estonia [PDF]
Estonian Journal of Earth Sciences, 2007 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 ...

New biostratigraphically important chitinozoans from the Kukruse Regional Stage, Upper Ordovician of Baltoscandia; pp. 218–224 [PDF]
Estonian Journal of Earth Sciences, 2015 Three new chitinozoan species, Conochitina savalaensis, Conochitina viruana and Belonechitina intonsa, are described. All these species are stratigraphically restricted to the Kukruse age (lowermost Sandbian, Laufeldochitina stentor chitinozoan Zone) and

Chitinozoans in the Wenlock–Ludlow boundary beds of the East Baltic [PDF]
Estonian Journal of Earth Sciences, 2007 The distribution of chitinozoans in the Wenlock–Ludlow boundary beds was studied in five drill core sections of the East Baltic. It was established that most of the typical Wenlock chitinozoan species became extinct in the uppermost part of the Jaagarahu
