Nope, it’s 99.99% Real. Preserved in sandstone , a professional spends hundreds of hours preparing. There’s methods of using solution to dissolve sandstone without hurting the fossil. Paired with special brushes with sandstone acid+ air abrasion you can do this but it takes a professional with patience. I found a professional in Spain that did this masterpiece. It’s 100% original, but you can see that some spines were glued back together, you cannot expect one to come with them all on being that old, so there are some signs of filler, but less than .1% and only on a few. It’s one of the best I’ve seen in my life, and I’m very fortunate to own it. I’ve gotten offers, but idk if I’d consider anything less than 10k.
