Here is a link to the actual paper:

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.” "

I suppose the source meteorite could have been ejected matter from an impact with another planet that harbored life; i.e., a sort of "meteor vector." That, to me, seems far more plausible than life developing out of nothing on a meteor or comet in space.
