Definitely bacteria but we don't know which type for sure as the fossil cells are long gone. Some of my colleagues think they are sulphur bacteria, while other colleagues think they are photosynthetic bacteria.
@@thm7217 yes! This rock is very precisely dated to 3.22 billion years old give or take 4 million years. We can get such a precise date because it's sandwiched between a volcanic ash layer and a lava which provide really good radiometric dates.
What kind of microbial remnants, do you think?

Any guess as to the age of this rock?

@@worksofein6449 I’m curious about the things that were “alive” that far back and how we can recognize them. Thank you😃
Hopefully we can figure that out with these new samples. I'll make a video as soon as I'm allowed to share details.
