Kasia Posted March 14, 2021 Share Posted March 14, 2021 Hello everyone, I came across this fossil on one of the auction sites - unfortunately the seller knows nothing about its age or even the country of origin. He sent me the following pictures, which however are not very sharp :(( Nevertheless, does it look like anything Ediacaran to you? The size is 17,5 x 12,5 x 2 cm. The guy says it's shale rock. What do you think? I will appreciate your comments :) Kasia Link to comment Share on other sites More sharing options...
Ludwigia Posted March 14, 2021 Share Posted March 14, 2021 I don't claim to be very familiar with Ediacarian fauna, so I can't say yes or no to your question, but I just wanted to say that this looks like either a flattened bivalve or part of the outer whorls of a finely ribbed ammonite to me. Probably the latter. 1 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
caterpillar Posted March 14, 2021 Share Posted March 14, 2021 No Ediacara fauna but a piece of Harpoceras from lower toarcien "schistes cartons" 1 1 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
Kasia Posted March 14, 2021 Author Share Posted March 14, 2021 Thanks @Ludwigia @caterpillar What about this one? It's much smaller - only 12 x 7 x 2 cm. Again - the seller claims no precise info.... Link to comment Share on other sites More sharing options...
