Abstract The Ediacaran–Cambrian transition marks one of the most important geobiological
revolutions in Earth History, including multiple waves of evolutionary radiation and …

The end‐Neoproterozoic transition marked a gradual but permanent shift between distinct
configurations of Earth's biosphere. This interval witnessed the demise of the enigmatic …

A uniform approach to ichnotaxonomy has been for the most part positively received by the
scientific community. We carry it further here, presenting a revised treatment of trace fossil …

Abstract The Cambrian 'Explosion', located by many authors between 540 and 520 million
years ago (Ma), is considered to be an abrupt appearance in the fossil record of most animal …

The radiation of bioturbation during the Ediacaran–Cambrian transition has long been
hypothesized to have oxygenated sediments, triggering an expansion of the habitable …

The Permian-Triassic mass extinction severely depleted biodiversity, primarily observed in
the body fossil of well-skeletonized animals. Understanding how whole ecosystems were …

Abstract The Ordovician of Scandinavia (ie Denmark, Norway and Sweden) has been
investigated for over two centuries and, through time, various chronostratigraphic schemes …

The evolutionary rise of powerful new ecosystem engineering impacts is thought to have
played an important role in driving waves of biospheric change across the Ediacaran …

Abstract The early Paleozoic Era (∼ 540–420 Ma) was an interval of profound
biogeochemical changes including increasing oxygen (O 2) and the onset of bioturbation …

Benthic animals profoundly influence the cycling and storage of carbon and other elements
in marine systems, particularly in coastal sediments. Recent climate change has altered the …
