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 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 …

The dynamics of how metazoan phyla appeared and evolved–known as the Cambrian
Explosion–remains elusive. We present a quantitative analysis of the temporal distribution …

The most successful chronostratigraphic correlation methods enlist multiple proxies such as
biostratigraphy and chemostratigraphy to constrain the timing of globally important bio-and …

Brachiopods are (perhaps all too) familiar to any geology student who has taken an
invertebrate paleontology course; they may well be less familiar to biology students. Even …

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

Among extant animals, Lophotrochozoa accounts for the majority of phyla. 1 This bilaterian
clade radiated rapidly during the Cambrian explosion, obfuscating its phylogenetic …

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 …

The lower to? middle Cambrian rocks (Terreneuvian, Series 2 and possibly Miaolingian) of
the Arrowie Basin are exposed superbly in the Flinders Ranges of South Australia. They …

Abstract Limestones of the ** Member of the Dengying Formation in the **aoyangba
section, South China, yield the oldest known Cambrian brachiopod–trilobite association. In …
