From what I've read, CI chondrites are extremely fragile and don't last very long on exposure to liquid water, which is why about half of the recovered CI chondrites on Earth have been witnessed falls (with the other half found in Antarctica). The two he analyzed for the paper were witnessed falls from 1864 and 1938.
I'm not saying this isn't just a case of pareidolia (it probably is), but the meteorites haven't been sitting in a stew of microorganisms for "thousands of years".
