Never seen something like this "Trilobite" (?)

I was doing some investigating into different types of Trilobite fossils and I came across these images.  I didn't know a Koneprusia, or any Trilobite fossil, could be this pristine (or that if fake that it could be so detailed a fake).  It doesn't look like what I thought because the spines seem bendy here and I thought they would be rigid from seeing other (way less detailed) specimens.  I also am not sure preparation could produce this level of clean detail on the "spikes" (?) show on all the spines.  Could this be a real fossil,  or could someone have created this level of fakery?  I kept thinking I had found the spikiest Koneprusia Trilobite out there until then suddenly I saw these photos.  Now I'm not sure what to make of them.

Hi,

 

We should not talk about fossil prices on TFF! It was written in the document you accepted when you arrived here. PFOLLEY is gonna scold you ! :Wink1:

That’s art! The koneprusia is real, but the secondary spines (on spines) are fake (just meticulously blasted matrix)! There are more than 10 different (sub)species of koneprusia, but the secondary spines are never like this - so that’s just art…

 

You have to give the preparator credit for making art like this, took a lot of time to blast the matrix in a shape of secondary spines, but here’s how a real spine on spine Koneprusia looks:

Talking about art… what’s the difference between fossil preparation and art? Here’s another fakery that was turned into art by adding fake spines on a real lichid (all fake spines glow white in UV, in pics below). Foto credit by Mike E.:

Thanks all for your responses, seeing how to tell fake spines from real using UV light is something for me to remember :)  And I'm glad to know that the Trilobite I posted images of is 'art' made from a fossil and not a natural specimen as its level of detail made my other specimens seem shabby otherwise.  With the preparation I've seen you capable of doing aeon.rocks I know your thoughts on this are authoritative  Thanks!

 

Appreciate the correction about including a price Coco, there are a lot of rules about how to talk about fossils here and I'm still learning.  I read the 'read first' posts but didn't recall seeing that discussing potential value was forbidden.  Will remember for next time.
