The Cambrian radiation was the explosive evolution of marine life that started 550,000,000 years ago. It ranks as one of the most important episodes in Earth history. This key event in the history of life on our planet changed the marine biosphere and its sedimentary environment forever, requiring a complex interplay of wide-ranging biologic and nonbiologic processes. The Ecology of the Cambrian Radiation offers a comprehensive and surprising picture of the Earth at that ancient time. The book contains contributions from thirty-three authors hailing from ten countries and will be...

"Calcareous algae and stromatolites" is shorthand for a wider array of organisms and fabrics that also includes calcified cyanobacteria, plus thrombolites and other microbial carbonates. Composition is the link: these are all important components of CaC0 sediments, from 3 Archaean to present and from the ocean floor to streams and lakes. It is hardly possible to examine limestones of any age without en- countering them. Simultaneously they are fossils, sediments, and en- vironmental indicators. It is the range of significance, coupled with the breadth of their distribution in time and space,...
