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 …

Trilobites are often considered exemplary for understanding the Cambrian explosion of
animal life, due to their unsurpassed diversity and abundance. These biomineralized …

Definition of early Cambrian chronostratigraphic boundaries is problematic with many
subdivisions still awaiting ratification. Integrated multi-proxy data from well-resolved regional …

A lack of well resolved biostratigraphic data has prevented robust regional and global
correlation of lower Cambrian successions from South Australia. A new early Cambrian …

International correlation of the lower-middle Cambrian boundary interval (Series 2-3, Stage
4-5) is difficult due to the paucity of globally distributed trilobite taxa and clear documentation …

Extant marine arthropods are afflicted by a variety of parasitic diseases making it plausible
that extinct trilobites also had a variety of parasites. Direct evidence in the form of preserved …

Antarctica and Australia were sutured together at the equator during the major pulse of
animal biodiversification associated with the Cambrian radiation. However, the lack of …

Abstract The Yangtze platform of South China offers evidence within its Ediacaran–
Cambrian geological record of the Cambrian explosion and diversification events in …

The discovery of new palaeoscolecid material (Cycloneuralia) from the Emu Bay Shale
Konservat-Lagerstätte of Kangaroo Island, South Australia (Cambrian Series 2, Stage 4) and …
