Stella Posted February 9, 2021 Share Posted February 9, 2021 I found this on a river bank in Louisiana. I've had it for years. I'm not sure what it really is. I would like to know though so I decided to ask this forum. Please help if you can. Thanks. compressor (1).zip Link to comment Share on other sites More sharing options...
Thecosmilia Trichitoma Posted February 9, 2021 Share Posted February 9, 2021 I wasn’t able to see the image, but would guess some sort of coral just from your description. (Look up favosites to get an idea of what I mean.) Try uploading the image directly to the forum so that it can be properly identified.

Stella Posted February 9, 2021 Author Share Posted February 9, 2021 I need help identifying my great find. I've had it for many years. I really don't remember where I got it. It looks like petrified or maybe fossilized honeycomb. I appreciate your help. 1 Link to comment Share on other sites More sharing options...
FranzBernhard Posted February 9, 2021 Share Posted February 9, 2021 Oh well, I was also expecting a favositid coral based on your description. Now I am stumped! I have not really any good idea, but I get a man-made vibe for this. Is it lightweight for its size? Is it a "rock" in the widest sense?

jpc Posted February 9, 2021 Share Posted February 9, 2021 can we see the back side, and maybe even a side view? Strange. 1 Link to comment Share on other sites More sharing options...
Rockwood Posted February 9, 2021 Share Posted February 9, 2021 I think this was formed by the dissolution of oolites, likely carbonate, from a more resistant matrix. Oolithic limestone would be the image to look for. 2 Link to comment Share on other sites More sharing options...

Rockwood Posted February 9, 2021 Share Posted February 9, 2021 Currently, it is considered to be polygenetic in origin; being the result of complex interaction of physical and chemical weathering processes, which include salt weathering and cyclic wetting and drying. Maybe I see a window for my idea ? 1 Link to comment Share on other sites More sharing options...
LabRatKing Posted February 9, 2021 Share Posted February 9, 2021 As @jpc and @Rockwood said, I agree this is an absolutely magnificent specimen of geologic origin. While not a fossil of a living organism, it is a fossil of a not often observed geologic process- a record of ancient earth chemistry to be treasured! 1 1 Link to comment Share on other sites More sharing options...
FranzBernhard Posted February 10, 2021 Share Posted February 10, 2021 These holes (are all of these holes or are there some positives also?) are so regular and smooth and roundish. Do these holes "interact" with each other*? Maybe I can see something like that, in the upper right, tree holes together, but I am unsure. I think, @Rockwood is into something - honeycomp weathering, very strongly influenced by preexisting roundish objects? *If the answer is no, a mold from a heap of "LECA" comes to my mind: LECA (link to wikipedia) @Stella, would you like to provide some further infos? Are there any positives, pics from the back, side etc., do the holes "interact"? Franz Bernhard 1 Link to comment Share on other sites More sharing options...
Pemphix Posted February 10, 2021 Share Posted February 10, 2021 Much to regular for honeycomb weathering imho. I get a manmade vibe here, like FranzBernhard said.... Link to comment Share on other sites More sharing options...
doushantuo Posted February 10, 2021 Share Posted February 10, 2021 I don't get a tafoni* vibe from this. *You might want to google that,in combination with,e.g.,geomorphology depending on size: transgressve ooid lag deposit,with the fines winnowed out SO: I tend to agee with Rockwood Link to comment Share on other sites More sharing options...
Rockwood Posted February 10, 2021 Share Posted February 10, 2021 You know all those infrastructure warnings you see in the news. Well admittedly not the headlines they should be, but, be that as it may, this happens to steel. Link to comment Share on other sites More sharing options...
Mahnmut Posted February 10, 2021 Share Posted February 10, 2021 Hello together. I have no real idea what this could be. One point speaks against it being ooliths weathered out in my opinion though: there is no single trace of a positive sphere to be seen as far as my eyes are not tricked by optical illusions. Not alveolar weathering in my opinion either. The cavities seem to originate on the same plane of surface, some kind of trace fossil? Another view may give further insight. And welcome to the forum by the way!

I have to advise of a possible bias, but this looks to have been cast as a fluid to me. The bias ? I've been fitting sheets of cement board today. It's a pebbly, bubble filled casting.

HuckMucus Posted February 10, 2021 Share Posted February 10, 2021 I'd like to see the back and the edge. There is something awful familiar with this picture, but I can't place it. When I blow it up, several seem to have what may have been "stems" (like an apple would have). They are not as uniform on closer examination. Aberrations to the "circle" seem to predominate 3 to 5 o'clock. It also brings to mind an egg mass, or maybe a squirrel stash of round seeds. Whatever it is, I enjoy the mystery and enjoy, and look forward to reading the opinions. Link to comment Share on other sites More sharing options...

abyssunder Posted February 10, 2021 Share Posted February 10, 2021 I think, that what you have there is a nice example of what MO Nature can give it for us.

Stella Posted February 11, 2021 Author Share Posted February 11, 2021 It's not heavy but also not lite. I don't think it's man-made bc, you can't see from the picture, but the holes are all of the way through out. It has a hard plastic feel to it. You are probably right. I appreciate your comment.

I think, after reading the comments, that it may be something made from hard plastic that has been weather worn, if I'm not misunderstanding the comments. So not honeycomb but still an awesome find. Thanks for the help. I've learned a lot. What a great forum! Link to comment Share on other sites More sharing options...
