Are these replica or genuine fossil?  They look like the same.

They both look slightly different look at the spaces between the vertebrae I think?:)

Although they are very similar, they have significant differences in detail.  As Will noted there are dislocations in the vertebral column in different places in the two specimens.  The vertebral column is shifted ventrally where it attaches to the skull, as Tim pointed out, but since the vertebrae are partially disarticulated this could be natural.  The dark body is too perfect given the fact that the skeletons had started to disarticulated; I agree with Snolly that paint may be involved.  As Snolly also pointed out these fish are common enough that they are not often replicated, I don't think I have seen an example of that being done.

 

Of course it is hard to judge from photos; an in-hand examination is always best.

I copied both images to my computer and zoomed into them. Aside from minor variations on how these were painted (and they were painted), they are bone-for-bone duplicates. Unless you believe in fish fossil doppelgänger, these are cast replicas. Seems odd that someone would go through the effort to fake this species as they are a reasonably common (but my no means the most common) species in the Green River Formation. I guess it would raise less suspicion to counterfeit $5 bills than $100's. 

 

Unless you were looking for some pretty artwork, I'd pass on these regardless of the price.

 

 

Cheers.

Don,

 

I noticed enough similarities to convince me they are nearly identical.

I reversed black and white, and circled the similarities I see on quick inspection:

There are enough slight differences between the two that might be explained by cast degradation from excessive use.

Indeed, I remain convinced they are the same. The apparent differences seen in the original posted images are the result of image scale, paint application variance, and lighting.  Ken and Tim's image manipulation to make them more compatible tell the tale. The mystery remains - why?

Why else? Practice. Can't do convincing fakes of something that is semi rare or just plain rare if you don't practice. Kind of like with prepping I suppose. Start with cheap throw away's before tackling the better stuff. Just my thought on it. :shrug:

Probably cheaper to make copies of one, than to buy multiple fish to sell.

  Looks very 'fishy' to me?  :)    I think Tim is on to something.

I may be wrong......

But the item is located in the Far East. Maybe easier to make a cast locally then import an original from the USA?

I have seen many specimens of this fish from the same seller who is in China.  As they look so perfect and similar. I begin to suspect that they are replicas massively produced in China.  I have no idea how much this relatively common fish from Green River Formation actually costs in the US, but it might be worthwhile to produce them massively for sale in China and get some profits.
