TL;DR: The "great Ordovician Biodiversification Event" (GOBE) as mentioned in this paper was a spectacular increase in marine biodiversity at all taxonomic levels largely within the phyla established much earlier during the so-called Cambrian Explosion.

TL;DR: The Great Ordovician Biodiversification Event (GOBE) as mentioned in this paper was arguably the most important and sustained increase of marine biodiversity in Earth's history, during a short time span of 25 Ma, an explosion of diversity at the order, family, genus, and species level occurred.

TL;DR: In this paper, the authors suggest that tropical water beneath the Inter-tropical Convergence Zone (δ18O = − 10‰ to − 15‰) was isotopically light reflecting high sea surface temperatures (SST) and reduced sea-surface salinity (SSS).

TL;DR: A stratigraphically constrained re-evaluation of terrane amalgamation in the Caledonides of northern Britain allows the development of a new orogenic scenario which accounts for many of the outstanding problems in the paratectonic CALEDONides and includes a new terrane template which correlates well with that proposed for Newfoundland as discussed by the authors.

TL;DR: Caradoc and Ashgill radiolarian cherts and siliceous mudstones from the Southern Uplands preserve primary rare earth element (REE) signatures which are comparable to those of more recent deposits from continental margin settings.
