do these look familiar to anyone, or know something similar to point me to a region? Found them in a box of Brazilian agates, but even *i* know better than that!

Not a clue but the first one sure is interesting.

I agree that the first one looks like a stromatolite (fossil algae).

Thanks guys! Yeah, now that I consider it, it’s fairly obvious. Since I have always lived in Wisconsin or Minnesota my idea of what a strom looks like is very different!
