Cicija Posted August 12 Share Posted August 12 I assume this Phacops is real but it looks polished to me. It is an internet auction and before I bid, I would like to hear from experts if everything is alright with him. 1 Link to comment Share on other sites More sharing options...
Kane Posted August 12 Share Posted August 12 A real specimen. It may have been tastefully enhanced, but I see no red flags. 1 1 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

FossilDAWG Posted August 12 Share Posted August 12 Careful treatment with an air abrasive can remove the matrix and give this shiny finish. I don't see obvious signs of a forgery, such as air bubbles or missing detail in the eye lenses. There is a crack, which has been tastefully repaired, which indicates that the specimen was found by cracking rock, recognizing the trilobite in cross section, gluing the pieces back together, and carefully prepping. I would be happy to own this specimen. Don 3 1 Link to comment Share on other sites More sharing options...

Kane Posted August 13 Share Posted August 13 Nice! Personally, whether it is a Moroccan or even a Penn Dixie bug, blasting at the end with baking soda is a nice finishing touch. Both won't be hurt by it even at higher pressure. Whereas dolomite will burn the shell, baking soda just polishes. 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
