The term “condensation” has been used in sedimentological research for 180 years and
ever since the last 80 years, its interpretation has become increasingly diverse and, to a …

Early marine seafloor lithification of carbonate sediments leads to the formation of
hardgrounds and is known from rocks as old as the Proterozoic. Hardground surfaces …

The 'Great Ordovician Biodiversification Event'(GOBE) saw a spectacular increase in marine
biodiversity at all taxonomic levels largely within the phyla established much earlier during …

Profound changes in the biodiversity and biocomplexity of marine life occurred during the
early to mid-Ordovician through an interval of some 25 Myr. The planet's seascapes were …

The experimental replacement of aragonite by calcite was studied under hydrothermal
conditions at temperatures between 160 and 200° C using single inorganic aragonite …

Trace fossils are common in the Ordovician and Silurian shallow marine carbonate
succession of Estonia, with 45 ichnofossil genera and five bioclaustration structures …

The encrusting tentaculitoid tubeworms (Middle Ordovician to Middle Jurassic) have their

A sequence stratigraphic framework predicts that time averaging and hiatus durations will be
long at times of fastest sea‐level rise. This prediction does not necessarily apply to …

The term “time-specific facies”(TSF) was introduced to the scientific community by the late
Otto H. Walliser to refer to unique facies typical of particular narrow intervals, some of which …

This study presents a compilation of the temporal distribution of 200 bryozoan genera during
the Ordovician. Bryozoans appeared in the earliest Ordovician (Tremadoc), diversified …
