Nothosaurus Posted March 24 Share Posted March 24 I would really appreciate advice on whether or not this matrix of shells or fossilized. It is being advertised as fossilized shells, but I want to make sure before I would purchase it. Thank you so much everyone for your expert advice.

DPS Ammonite Posted March 24 Share Posted March 24 (edited) Where is it from? Texas has a similar commercial stone with lots of Trigonia clams. https://wap.stonecontact.com/cordova-shell-limestone/s15806 Edited March 24 by DPS Ammonite My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere. Link to comment Share on other sites More sharing options...
Brian James Maguire Posted March 24 Share Posted March 24 Yes they are real, but its difficult to tell from the photo what is shell and what is imprint, but certainly some of them has the shell present Link to comment Share on other sites More sharing options...
Ludwigia Posted March 24 Share Posted March 24 I'm just seeing imprints and not the shells themselves. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

On further examination of photos i think you are right no shells just impressions but they are at least real imprints Link to comment Share on other sites More sharing options...
Rockwood Posted March 24 Share Posted March 24 I prefer to call them external molds, because they record the external shape of the shell. 1 Link to comment Share on other sites More sharing options...
Nothosaurus Posted March 25 Author Share Posted March 25 This matrix of shells is for sale and the description says it is a fossil. I would greatly appreciate any advice on whether or not this seems to be a genuine, fossil, or a more modern matrix. Thank you so much for your expertise everyone.

shark57 Posted March 25 Share Posted March 25 Those are most likely fossil shell imprints, but knowing where they were found could help confirm that. Link to comment Share on other sites More sharing options...

Thank you so much for your expertise everyone. This matrix surely looks like genuine rock. Its cost shouldn't be significantly more than the price of materials to create a fake, anyway.

Nothosaurus Posted March 25 Author Share Posted March 25 I want to thank everyone for their amazing thoughts and advice! So many came to my rescue! This is such a fantastic forum! The responses I’m getting make me think it is genuine. Someone asked if I knew where it was from. No location was given so I am unsure. Thank you again my fossil friends!
