booratino Posted March 17, 2017 Author Share Posted March 17, 2017 >> Are You saying You think it is a crinoid calyx? I supposed first that it may be core of Platycrinus symmetricus, number 8 on this picture: http://old-animal.ru/pict.php?rid=827 But now I'm not sure, if You can check kindly deleted by admin ebay refs, You will find that some thunder eggs looks like "Cell division". So I think that it's possibly unicellular something. But why this unicellular shell armored? Link to comment Share on other sites More sharing options...

Please tell me how this creature's name is and I will post link to scientific documentation. You presume that it is a "creature" when most members responding think it is geologic in origin. If you want to make a nice argument for being a fossil, then please provide something more substantial than a "seller's" link or description.

Yes it is a geological rock and has no biological connection. 1 Link to comment Share on other sites More sharing options...
JohnJ Posted March 17, 2017 Share Posted March 17, 2017 @booratino You might get a good explanation at a local university or museum. If you are close to Moscow, you could try to contact someone at the Paleontological_Institute,_Russian_Academy_of_Sciences.

booratino Posted March 17, 2017 Author Share Posted March 17, 2017 >> https://en.wikipedia.org/wiki/Thunderegg Ok, please explan me how volcano can make 6 symmetrically arranged surfaces, covered with mother of pearl? ps: some of thundereggs I saw are really geological, but another, like this one, are different. >> If you are close to Moscow, you could try to contact someone at thePaleontological_Institute,_Russian_Academy_of_Sciences.

It is a mineral that looks like mother of pearl, but it is not! 5 hours ago, booratino said: : some of thundereggs I saw are really geological, but another, like this one, are different. All thundereggs are geological. They may look different but they are formed in the same manner. 2 Link to comment Share on other sites More sharing options...
doushantuo Posted March 17, 2017 Share Posted March 17, 2017 once again,i have to side with Tony. I have only a very modest understanding of silica diagenesis and bivalve mineralogy,but I don't think that is nacre Amazingly enough both nacre and opal formation proceeds from amorphous precursor phases. It's a funny ole world The formation of thundereggs seems to be correlated with rhyolitic volcanism. Well,that figures 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 17, 2017 Share Posted March 17, 2017 @booratino, Unfortunately, we must agree to disagree. You will not change any of our minds on this being geological, and obviously you are convinced otherwise. Your ideas just aren't being entertained here, and I'm afraid that further discussion would be counterproductive. As such, I am locking this thread. We hope you get an answer to your questions, although I suspect we have already done so. Best of luck to you in your quest for answers.
