MyGodMagma Posted May 17, 2021 Share Posted May 17, 2021 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. 1 "Excellent!" I cried. "Elementary," said he.

It's more of a sense than anything I can articulate though. The upper ones on that surface show hints of containing crinoid columnals, but that isn't so clear either. The other views bring to mind the ichno fossil Diplocraterion. When it comes to iron clad identifications. Link to comment Share on other sites More sharing options...
Mahnmut Posted May 18, 2021 Share Posted May 18, 2021 Hi, may the whole thing be a piece of thick bivalve shell with borings of some other organism? Just wondering.
