The paper Aerobic microbial life persists in oxic marine sediment as old as 101.5 million years [1]: > Our results suggest that microbial communities widely distributed in organic-poor abyssal sediment consist mainly of aerobes that retain their metabolic potential under extremely low-energy conditions for up to 101.5 Ma. > Dominant bacterial groups included Actinobacteria, Bacteroidetes, Firmicutes, Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, and Deltaproteobacteria (Fig. 3b, c) with a minor fraction of Chloroflexi (0– 2.6%). It seems that it is the conditions that extends life since such a diverse community of aerobes was "reanimated".
