Following the Cambrian Explosion and the appearance in the fossil record of most animal
phyla associated with a range of new body plans, the Ordovician and Silurian periods …

Correlation of Hirnantian sections of the Baltoscandian Basin reveals four major
transgressive-regressive sea-level cycles related to waxing and waning of ice sheets at high …

The Baltoscandian epeiric sea was characterised by relatively slow but continuous
carbonate deposition from the Middle Ordovician up to the Silurian. Relatively good …

Carbon isotope changes during post-Hunnebergian Ordovician time were investigated. As
the corresponding sequence of rocks is stratigraphically nearly complete in Baltoscandia, an …

δ13C values of numerous limestone samples from Katian (Upper Ordovician) successions in
Oklahoma and the Upper Mississippi Valley document the presence of at least three of the …

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 …

Results of conodont-based δ 18 O phos studies from two core sections in Estonia
(Mehikoorma-421 and Valga-10) indicate that the pre-Hirnantian Late Ordovician was …

The latest Ordovician and earliest Silurian carbonate succession of the East Baltic region
has served as a global reference for studying the Hirnantian mass extinction and global …

The diversity data presented in this paper are based on recently revised collections of
conodonts from outcrops (northern Estonia) and core sections of Estonia and western and …

Sea level changes are the main mechanism controlling facies dynamics, stratal geometry
and temporal variations in fossil assemblages in marine sedimentary basins. Besides …
