Cambrian

Geological Society, London, Memoirs, 1992
Abstract Aspects of the history of the Cambrian System, and especially its usage in the British Isles, are discussed by Holland (1974). Rushton (1974), Cowie (1974) and Dhonau & Holland (1974) give general accounts of Cambrian stratigraphy in the British Isles, with extensive bibliographies, and the correlation is discussed by Cowie et al.

Crustaceans and the "Cambrian Explosion"

Science, 2001
We noted with interest the report by Siveter et al . ([1][1]) of new phosphatocopid specimens showing soft-part preservation from the Lower Cambrian Comley Limestones, but we question some of the interpretations both in the report and in the accompanying Perspective by Fortey ([2][2]). First,

Morphological Disparity in the Cambrian

Science, 1992
An analysis of the range of morphology among arthropods demonstrates that disparity among living arthropods is similar to that in Cambrian arthropods. The range of morphological design resulting from the Cambrian "explosion" has been overestimated, reflecting a tendency to separate as "problematic" taxa that cannot be accommodated in the classification

Cambrian enigmas

Geology Today, 1987
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.
