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 ...

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.

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 ...

EARLY LLANDOVERY CHITINOZOANS FROM JORDAN [PDF]
Palaeontology, 2009 Abstract: Chitinozoans recovered from cores BG‐14 and WS‐6 in southern and eastern Jordan are described. Sample ages are well‐constrained by graptolite data to the ascensus‐acuminatus and vesiculosus graptolite biozones. Eighteen chitinozoan taxa are recognized, with Spinachitina fragilis, Plectochitina nodifera, Ancyrochitina laevaensis and ...

Chitinozoans and scolecodonts from the Silurian and Devonian of Japan [PDF]
Island Arc, 2019 AbstractSilurian and Devonian chitinozoans and scolecodonts are recorded from strata of the Hida‐Gaien Terrane, central Honshu. Silurian chitinozoans include Eisenackitina, Bursachitina, and the species Angochitina elongata. The latter provides a precise biostratigraphical tie between the Japanese succession and the Type Ludlow Series of the Welsh ...

Ordovician chitinozoans and acritarchs from southern and southeastern Turkey [PDF]
Revue De Micropaleontologie, 2007 Revision of the lithostratigraphy of Ordovician deposits in southern and southeastern Turkey led to a re-evaluation of the age assignments of formations identified in the subsurface and at outcrop. Previous datings were based on macrofauna (mainly trilobites and graptolites).

Chitinozoan diversity in the East Baltic Silurian [PDF]
Estonian 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

Chitinozoan biostratigraphy of the Přídolí Series of the East Baltic [PDF]
Estonian Journal of Earth Sciences, 2011 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.

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
