Are there species of bacteria that are substantially unchanged in a billion years?

Morphologies of cyanobacteria show that fossils from billion+ years ago show little change. https://en.wikipedia.org/wiki/Stromatolite

No way to know for sure. But many bacteria today look very similar to what little bit of maybe fossils we might have.
