Badia Posted November 25, 2018 Share Posted November 25, 2018 Hi, I would like to ask you if you happen to know what these fossils are. They were found in central Spain, on a farm field that I have learned to be a not well-known Miocen limestone lacustrine site. It remineded me of petrified wood when I first saw it and then I thought it could be coral. However, if you look carefully you can see that it was possibly part of a rould-like creature as I could find several pieces that actually fit. As you can see, the creature was not all the same as part of the surface where the pieces seem to assemble look totally different. The surface is not perfectly round. Please let me know if you happen to know what it is. Thank you! Link to comment Share on other sites More sharing options...
ynot Posted November 25, 2018 Share Posted November 25, 2018 It looks mineral like to Me , not seeing a fossil. Does it "fizz" when vinegar is dripped on it? 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

I agree; ...and if it doesn’t react with vinegar, than I would consider the hypothesys of a fibrous/radiating baryte nodule https://www.researchgate.net/figure/Baritina-formazione-raggiata-mm-80x70_fig4_272151800 http://www.mineralimodenesi.it/Schede foto/Valle Urbana/Barite/0088A Baritina.htm ciao 2 Link to comment Share on other sites More sharing options...
Badia Posted November 27, 2018 Author Share Posted November 27, 2018 Supertramp, you may be right, looks very much like a baryta radiating nodule, thank you! It does pfzz a bit, not very much. But if you look at the 3rd picture, don't you see a strange-looking organic soft texture? Link to comment Share on other sites More sharing options...
