Si. Zhmur et al., Comparative morphology of modern and ancient terrestrial bacteria and microfossils from carbonaceous meteorites, MICROBIOLOG, 68(6), 1999, pp. 739-745
Comparative analysis of bacteriomorphic structures in the Murchison and Efr
emovka meteorites and ancient high-carbon black and oil shales showed that
they are analogous to modern microorganisms and their lithified remains in
modern halophilic and thermophilic cyanobacterial communities (mats).
