Has anything been done to this fossil?

Recommended Posts

I'm pretty new to buying fossils, and I noticed some nice looking trilobites and other stuff from this same seller. I can't tell if it's been painted or repaired or anything. 

 

Has it? It looks a little shiny. Not sure why...

It may have a light application of matte varnish.  That can easily be reversed with acetone.  

It could also be glare from flash or lighting.  To be certain you should ask the seller directly.

These are often times "prepped" by using a wire wheel or wire brush, this adds more shine to an already pretty shiny preservation.

Here are the photos from the auction site. Those trilobites look alright to me.

The larger one looks like it was glued back together. There's an obvious crack running through the left side of the cephalon. That's however nothing unusual for these trilos, which, by the way, are quite common on the market.

These are often air-abraded and I suspect that gives them a bit of a shine too.

Thanks everybody. I wrote the seller to ask why they're so shiny. Having read your posts and stared at the fossils for a little while, I think it's more of a polished look rather than a chemically coated look. Almost like someone buffed them.

 

I used to collect coins, and some other coin collectors are so incredibly strict about having their coins be completely original with no alterations (e.g. cleaning) it can be rather ridiculous. I'm glad to see that fossil collection is not so heavily plagued by this tendancy.

Got this response feom the seller. Not too detail an answer, but whatever...

 

"Thank you for the email.
This one is totally natural, not coating or anything like that. The fossil is just different than the matrix.
Have a great day!"

I see enough marks on your close up pix that i think these were indeed prepped with a wire brush on a Dremel.  That definitely makes them shiny.  Air abrasion generally does not make these Utah trilobites shine.
