The Great Ordovician Biodiversification Event (GOBE) is Not a Single Event
Paleontological Research, 2021 . The Ordovician biodiversification is considered one of the most significant radiations in the marine ecosystems of the entire Phanerozoic. Originally recognized as the ‘Ordovician Radiation’, a label retained during most of the 1980s and 1990s, the ...

Ordovician scientometrics [PDF]
Estonian Journal of Earth Sciences, 2023 Scientometrics is a tool for studying the development of science to observe and analyse patterns that emerge from it. Our aim is to elucidate how the Ordovician has been studied through the years, through the perspective of the published papers, the main

Ordovician Bryozoa of Estonia [PDF]
Estonian Journal of Earth Sciences, 2023 sessile colonial, filter-feeding animals, many of which possess hard carbonate skeletons of different morphology. The bryozoan faunas of the Ordovician of Estonia were studied early by famous naturalists such as Karl Eduard von Eichwald and WÅadisÅaw ...

An Ordovician ostracod palaeopsychrosphere? [PDF]
Estonian Journal of Earth Sciences, 2023 Ostracods are tiny bivalved crustaceans with a fossil record extending into rocks of the Lower Ordovician. They occupy almost all aquatic environments today, from the ocean abyssal planes to damp forest leaf litter.

The Great Ordovician Biodiversification Event (GOBE): definition, concept and duration
Lethaia, 2018 The Ordovician biodiversification has been recognized since the 1960s; the term ‘The Great Ordovician Biodiversification Event’, abbreviated by many as the ‘GOBE’, has been used for the past 20 years. The conceptual development and terminology applied to

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

High potential for weathering and climate effects of non-vascular vegetation in the Late Ordovician [PDF]
Nature Communications, 2016 It has been hypothesized that predecessors of today’s bryophytes significantly increased global chemical weathering in the Late Ordovician, thus reducing atmospheric CO2 concentration and contributing to climate cooling and an interval of glaciations ...

Diversity dynamics of Ordovician Bryozoa
Lethaia, 2018 This study presents a compilation of the temporal distribution of 200 bryozoan genera during the Ordovician. Bryozoans appeared in the earliest Ordovician (Tremadoc), diversified rapidly until the late Sandbian, and then suffered three distinct ...

Glacial onset predated Late Ordovician climate cooling
Paleoceanography, 2016 The Ordovician glaciation represents the acme of one of only three major icehouse periods in Earth's Phanerozoic history and is notorious for setting the scene for one of the big five mass extinction events.
