Abstract The Cambrian Period is the first period of the Phanerozoic Eon and witnessed the
explosive appearance of the metazoans, representing the beginning of the modern earth-life …

Use of the first appearance datum (FAD) of a fossil to define a global chronostratigraphic
unit's base can lead to intractable correlation and stability problems. FADs are diachronous …

Appearance of metazoans with mineralized skeletons,“explosion” in biotic diversity and
disparity, infaunalization of the substrate, occurrence of metazoan Konservat Fossil …

The late Neoproterozoic ocean witnessed the naissance of animals which is believed to
have been stimulated by an increase in oxygen levels in the ocean. However, apart from the …

The International Subcommission on Cambrian Stratigraphy has introduced a number of
internal subdivisions (ie, series and stages), but most of the explanatory publications lack …

Data on the first appearances of major animal groups with mineralized skeletons on the
Siberian Platform and worldwide are revised and summarized herein with references to an …

Abstract The Ediacaran–Cambrian transition is a critical interval marking drastic biological,
oceanic and geochemical co‐evolutions in geological history, but it is poorly constrained …

Twenty candidate fossils with claim to be the oldest representative of the P hylum P orifera
have been re‐analysed. Three criteria are used to assess each candidate:(i) the diagnostic …

Lower Cambrian successions described from Scandinavia are reviewed and subjected to
sequence stratigraphical analysis; comparisons are also made with successions described …
