The Cambrian diversification of animals was long thought to have begun with an explosive
phase at the start of the Tommotian Age. Recent stratigraphic discoveries, however, suggest …

The evolutionary trajectory of early complex life on Earth is interpreted largely from the
fossils of the Precambrian soft-bodied Ediacara Biota, which appeared and evolved during a …

Abstract The Ediacaran Period follows the Cryogenian Period in the wake of a snowball
Earth glaciation and precedes the Cambrian Period with its rising tide of animal radiation. It …

The Ediacaran System and Period was ratified in 2004, the first period-level addition to the
geologic time scale in more than a century. The GSSP at the base of the Ediacaran marks …

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

Ediacaran macrofossils from the Avalon Terrane (primarily eastern Newfoundland and the
central UK) record some of the earliest large and complex multicellular organisms on Earth …

Benthic marine macroalgae or seaweeds are key ecological players in oceans today and
have been since the Proterozoic. To date, however, morphological and evolutionary patterns …

Abstract The Nama Group exposed on the Neint Nababeep Plateau along the Orange River
in northwestern Republic of South Africa is now recognized as an expanded record of the …

A growing number of detailed geochemical studies of Ediacaran (635–541 Ma) marine
successions have provided snapshots into the redox environments that played host to the …

It is beyond doubt that the appearance of infaunal bioturbation and metazoan
biomineralization across the Ediacaran–Cambrian transition irreversibly affected the nature …
