The faunal (all fossil groups) species diversity curve for the Ordovician of Norway shows a strong and statistically significant cycle with a period of 12 to 14 million years. The cycle is supported b...
Well preserved relief specimens of the dendroid graptolites Dendrograptus rigidus Bulman, 1936 and Acanthograptus sp. have been discovered in a siltstone within the basal Engervik Member of the Elnes ...
Two species belonging to the Class Stelleroidea are described from Ordovician rocks of the Oslo Region, Norway. These are the asteroid, Cnemidactis osloensis n.sp, from the Elnes Formation (Llanvirn) ...
The aim of the present study is to improve knowledge of the brachiopod fauna in the lower part of the Arnestad Formation (Caradoc) in the Oslo-Asker district and to document faunal changes prior to th...
Conodont faunas from the kukersites and kukersitic limestones of the Kiviõli Member are similar to coeval collections from other sedimentary facies and there are no taxa endemic to this unusual...
Sequences of the Leetse Formation were studied in order to find out the conodont biozonation, grain-size distribution, and glauconite mineral properties and their variations along the North Estonian K...
Biozones of the East Baltic Early Ordovician trilobites were studied based on the trilobite distribution in northwestern Russia, Estonia, and Sweden. New data on trilobite distribution reveal the diac...
Over 150 years of progress in the Ordovician geology and stratigraphy of Estonia has resulted in one of the most precise Ordovician timescales in the world. In this paper, an up-to-date version of the...
The distribution and composition of dolomitized rocks and stoichiometry of dolomite in southern Estonia in the Ordovician, Silurian, and Devonian were studied on the background of the facies, sediment...
A new species Conochitina rugata, earlier treated as nomen nudum, is formally defined. The species has been identified in the upper part of the Pirgu Stage in many East Baltic sections of the Baltica ...
The current state of and the latest developments in the conodont-based biostratigraphical studies of Upper Ordovician and lower Silurian strata in Estonia are discussed. An updated conodont zonation i...
More than 150 Ordovician and Early Silurian brachiopod species have been assigned to the genus Platystrophia King,1850 mainly on the basis of their Spirifer-like shell exteriors. King’s concept o...
This is the first record of Cornulites sp. as an epibiont on brachiopods from the middle Ashgill, Late Ordovician, of the South China Palaeoplate. Twenty-one cornulitid specimens were found attached t...
Integrated palaeontological and sedimentological study of the Upper Ordovician Vormsi Stage in the Lelle drill core section, Central Estonia, revealed an association of shelly fauna containing the end...
Conodonts of the uppermost Uhaku, the Kukruse, and the lower Haljala stages (uppermost Darriwilian and lower Sandbian) of Estonia are discussed. The distribution of conodonts within the Pygodus serra,...
