The Journal of Cosmology website looks a little sketchy to me -- not what I would expect from a serious science publication.
Even if he could conclusively prove that he is seeing a fossil in a meteorite you couldn't discount the idea that these meteorites were blasted off the earth's surface and into space by some ancient, huge asteroid strike and fell back to earth at a later date. That seems more likely to me than bacteria developing on a comet which is what he is suggesting.
That being said I had never heard of this class of meteorite. Here is a description from the paper by a chemistry professor who analyzed one in 1806,
"He realized that these stones were different from all other meteorites since they had the appearance of solidified clay. Thénard reported that “when the stones were placed in water they disintegrated immediately and gave off a strong clay-like odor.” "
They have a pretty picture in the news story, certainly, but I will wait for independent confirmation before I even begin to consider the possibility that this may be true, as opposed to a carefully-selected picture culled from gigabytes of data. Not because I have preconceptions either way, but because that's how little I value NASA's announcements on this front.

Something seems odd here - the guy has made this same announcement in the past.

Even assuming the possibility of bacteria contagion from Earth the question remains how the biological remain appears to contain no nitrogen, an essential building block to life as we know it.
To simplify we are made of cells and breathe oxygen but I would argue life can exists in other forms than one we know.
This just screams credibility.
