Biomineralized skeletons are widespread in animals, and their origins can be traced to the
latest Ediacaran or early Cambrian fossil record, in virtually all animal groups. The origin of …

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 …

Small shelly fossils (SSFs) occur widely on the Yangtze Platform and have great potential for
biostratigraphic subdivision of pre-trilobitic Early Cambrian strata. Based on the SSF record …

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 …

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 …

Given the high oxygen demands of complex metazoans, a sound understanding of marine
redox conditions is essential to reconstruct the factors that lead to the dramatic increases in …

Fossilized embryos from the late Neoproterozoic and earliest Phanerozoic have caused
much excitement because they preserve the earliest stages of embryology of animals that …

A trace element study is presented of two Ediacaran–Early Cambrian sedimentary
successions in South China: the Shatan section, Sichuan Province, which represents a …

In order to constrain marine redox conditions for the sedimentary environments immediately
preceding the rapid diversification of metazoans carbon and sulphur isotopes, as well as …

Accumulated records of organic microfossils span billions of years of Earth history. The
majority of this record consists of prokaryotes plus eukaryotes of a protistan grade, yet this …
