The diversification of animals during the Cambrian Period is one of the most significant
evolutionary events in Earth's history. However, the sequence of events leading to the origin …

Abstract The Terreneuvian Series of the early Cambrian records the first major diversification
phase of the canonical Cambrian explosion. However, a paucity of precise radio-isotopic …

Abstract Small Shelly Fossils (SSFs) are globally distributed across various continents in the
early Cambrian and especially critical for the Terreneuvian biostratigraphic subdivision and …

Hyolitha represent one of the major constituents of the Cambrian Evolutionary Fauna, first
appearing in the Terreneuvian and rapidly diversifying soon after. Recent work has both …

Small shelly fossils (SSFs) are a useful and critical tool for subdivision and correlation of the
Cambrian Terreneuvian stratigraphy. The Maidi** Formation in southern Sichuan is a well …

Abstract The Ediacaran–Cambrian transition, one of the major turning points in Earth's
history, is characterized by an epoch-making change in biosphere. In South China, the late …

Simple Summary Aldanella attleborensis, is a mollusk fossil found worldwide; its first
appearance datum (FAD) has been suggested as one of the potential markers for defining …

Early Cambrian small shelly fossils (SSFs) represent some of the earliest biomineralized
examples of metazoans and are often extremely abundant and diverse, so can be useful for …

The abrupt appearance of abundant small shelly fossils (SSFs) near the base of the
Cambrian System signals a key event in the evolutionary history of the Kingdom Metazoa …

Abstract The Niuniuzhai section in Leibo County, southern Sichuan, China, is part of the
western carbonate platform of the Yangtze Block. The section is crucial for correlating early …
