Keichousaurus restored?

[JBkansas]

Not an obvious fake, bones appear 3d although the lines one either side of the abdomen look painted to me. Would love a little input from others before I buy.

 

Seller's has another keich with bones slightly laterally displaced at a crack (which is something that would happen with real fossils but probably wouldn't be done with a fabrication).

I've always stayed away from these because I can't really tell for sure what is fake from pictures.  However, if you blow up the pictures, the humerus bones in the front legs are noticeably different in length.  That would bother me.

if you are unsure try to remove the color

most of them are prepped with engravers and bones go lost

good bones are visible, you can see the internal structure when the engraver works to deep..

The seller listed another keich with a missing tail after a break in the matrix, said it turned out to be painted on when he tested it so he removed it. Seems to be a legit dealer with the standard quality wire brush prep keiches.

I was wondering what the spots that looked like matrix were in the bones, guessing those are areas the grinder cut into the marrow (or through the bone altogether).

I dont see any red flags on the specimen.   The arms and legs are similar.  The prep is not the best as is the preservation and you might have some paint on the digits and skull hard to tell, need closeup photos.

In my opinion the keichou looks real, I follow Troodon in his assessment

Many on the market, not necessary to fake them. But I agree, prep is low

When I blow up the picture of the specimen a  bit, I don't see rib ends in the total lengths where the red arrows point, I see what looks like blobs of paint.  I also see other places like in the digits that look painted and bones that don't look right (maybe gauged by poor prepping).  So this piece definitely seems to display restoration to me.  Am I looking at this incorrectly?

 You're correct that does look odd, had not observed that feature.  Not sure what to make of it but could be as you indicated.   Boy these are tough call when your only looking at them through photos and not hand inspecting.  

[JBkansas]

I thought that could be the rib ends but it seems odd that they'd all line up like that.

Genuine specimen, but badly prepped by acid and mechanical means.

I agree, this is reall but very poorly prepared (like a lot of the real Keichousaurus fossils you see).

There must be something about keiches that make them prone to poor prep, the seller has pieces that look like they could be in a museum (one reptile skeleton had teeth and patches of scales) and all his keiches look like the same normal poor prep.

Is it the Keichousaur's fault they are prone to poor prep or is it that humans have discovered a trove of well preserved fossils, yet decided to maximize profits by doing a botch prep job for the international fossil market? I think our perception is that we are buying a priceless natural treasure, but the participants in the fossil trade bringing this specimen to you would regard it as a commodity by which they can feed their families. I am at a loss to make a moral judgment, but there are always more than 1 side to the story.
