It is hoped that textbooks and websites will now focus upon recent and more robust discoveries of microfossils of a similar age from Western Australia, also examined by us in the same article.» (sciencedaily.com)
«Periods of very intense North Atlantic circulation and higher Northern Hemisphere temperatures increased the preservation of microfossils in the sediment cores, whereas those with slower circulation, when the study site was primarily influenced from the south, were linked with decreased carbonate ion concentrations at our core site which led to partial dissolution,» said co-author Dr Luke Skinner, also from Cambridge's Department of Earth Sciences.

The book provides an interesting, in - depth, but very readable discussion of research on the earliest life on Earth and especially on microfossils. (distantearths.com)
