Within the Cambrian about six globally traceable extinction events are recognised, of which those across the Mid Botomian through to Toyonian/Amgan are of highest order. All events are associated with facies changes, mostly combined with stepwise extinctions that preferentially affected nearshore and endemic taxa.

Journal of the Geological Society of Australia, 1963
Abstract The Cambrian System by definition must include the rocks (in the Caledonian geosyncline of Wales) to which this name was first applied. Its type sequence, however, does not define its boundaries. Evidence on the base of the Cambrian can be found in the Caledonian sedimentary areas of Scandinavia and in the adjoining Baltic region where the ...

Bizarre soft‐bodied animals from the Cambrian, principally the Burgess Shale of British Columbia, are throwing new light on the major diversification of early metazoans. A distinctive range of new body‐plans hint at explosive rates of evolution, but the underlying mechanisms are still a matter for conjecture.

Abstract The order in which the distinctive body plans of different kinds of animal evolved is still not clear. There were fundamental themes, however, which often recur. Some are about moving about, especially segmentation, but most of them are about eating: tentacles, jaws and, above all, the mouth.
