Subject: fossilized bacteria in meteorites
At a conference in Denver, July 20-22, 1999, a pair scientists
from the Russian Academy of Sciences presented sharp images that
look very much like fossilized microorganisms taken from fragments
of several carbonaceous meteorites. The scientists are Stanislav
I. Zhmur, Institute of the Lithosphere of Marginal Seas, RAS,
and Lyudmila M. Gerasimenko, Institute of Biology. The conference
was "Instruments, Methods and Missions for Astrobiology II," the
third in a series organized by NASA's Richard Hoover. In December,
The conference proceedings became available from The International
Society for Optical Engineering (SPIE), the conference sponsor.
We contacted Dr. Zhmur and asked permission to publish some of
those images on the Cosmic Ancestry website. He agreed. He
comments:
"Comparative analysis of bacteriomorphic structures from the
carbonaceous meteorites, Murchison, Efremovka and Allende,... and
morphology of microorganisms of modern and ancient terrestrial
cyanobacterial community showed that they are analogous. This gave
us reason to consider that these bacteriomorphic structures are
fossilized remnants of microorganisms. The lithified remnants
...are tightly conjugated with the mineral matrix, removing the
possibility that they are contaminants. The selection of
microfossils capable of being interpreted as biological is quite
wide. Some of them are demonstrated in the pictures."
Six images from the Murchison and Efremovka meteorites with
captions and additional comments by Zhmur are available at
