I suspect this is a stromatolite (and not a stromatoporoid) after reading up on both, but seeing as I’ve never found either before, I wanted to put this past the experts. I do see some structures that could possibly be “pillars” but I’m just not convinced that’s what I’m looking at. Any opinions shared are very greatly appreciated, thanks!

After a 3 month dedicated search (coughSisyphean) to figure this out on my own, I still can’t find anything that remotely looks like this. I’m a longtime SE LA/SW MS creek gravel rockhounder and I’ve never come across this before. I’ve shown it to some other area collectors-no luck. This was found in a creek running through the upper terraces of the (pre-loess) La Citronelle formation not far from the Amite County, MS border. *I should also mention that Louisiana gravels within the (Plio) Citronelle contain much older rocks/fossils that are believed to have been transported by glaciers, as well as ancient interbraided streams. Frequent flooding subsequently washes these out of the upper terraces. To my eye, though, this piece doesn’t appear to be rounded or very worn. If I had to call it, I’d say table coral/freed piece of reef, but that one side having the appearance of muscle attachment grooves has me wondering about that. I greatly appreciate your time and opinions; thanks for giving this an eyeballing for me.

Requesting assistance identifying the dark slug-looking forms, these look like they were once soft-bodied so I'm pretty lost. I haven't the foggiest idea what these are and my fossil reference books don't have anything that looks like this in the photos or illustrations from what I can see. This was a creek find in southeast Louisiana. Your time and expertise are very much appreciated by this fossil newbie, thanks.
