Viruses in carbonate precipitation ? the new frontier in Earth Sciences ?

Maurice Tucker - University of Bristol

Viruses are very much in the news these days, unfortunately, but what about their geological history? Are viruses preserved in the fossil record, considering they are so small and you cant even see them ? If they are, how does that happen and how far back do they go? And what about the roles of viruses in the environment? Are they significant or were they just the nasty invisible parasites we regard them to be today, disrupting life as we know it ? Or are they both – good and bad?
