Can someone tell me if this looks like a stromatolite fossil?

Front opening showing six loops of formation. This side has obvious breakage of some pieces.

Back aperature showing three "gills"

Back aperature closer up

Here are additional views via hubs:

We describe the larger aperature as front - it's got more obvious damage to the structures.

Look at this fossilized clam I cut today! I have more #rockhounding content coming as soon as I edit it.

I can't believe how many rocks I've collected and not cut yet! So excited to keep sharing this year.

Found this in the black leaf formation in Montana. Any ideas what it might be? #fossil #fossilid #paleontology #geology

Ok, Paleontologists of Bluesky, I need your help! As I have no locality on these fossils, do any of you have ideas as to what species these might be?
Also, any good database on icthyology?

For #fossilfriday I bring you what may be a trackway from stone found in a pile downstream of the dam in Turner's Falls, Massachusetts. #ichnology #fossilid
