Hi
This Psittacosaurus is offered for sale (from a collection in Germany, not China).
The seller says that the bones have been found disarticulated and have then been assembled onto an artifical matrix. 

 

I was wondering if you could give me an opinion about the bones? Unfortunately I do not have better, high-resolution pictures.
To me the skeleton looks pretty good. However, some bones of the feet and the tail are probably taken fromfrom another animal (darker color)? Also, there is probably significant reconstruction on the head?

Unfortunately most of the Psittacosaurus that are currently selling are Frankenbones. In the case of this particular specimen, these are the bones that I am absolutely sure are not part of the original skeleton;

But I do not rule out the possibility that there are others...

 

Photos of better resolution and with good lighting for cases like this are very much essential, and yet nothing replaces a face-to-face exam.

I'd say those vertebrae and legs look pretty promising. But the skull looks quite dubious. There might be crushing, but the anatomy doesn't quite look right.

Yes. The skull somehow looks a bit weird. It's difficult for me to say why exactly though.

I think the "face" is ok. However, the opening behind the eye (inferior temporal fenestra?) one the right side of the skull is bothering me somehow.

Yeah, it wouldn't surprise me if the skull was composited or partially constructed.

I've seen tons of Psittacosaurus skeletons at the Tucson show.  Most were composites but typically had no restoration since lots of sketal material is available and that included the skulls.  I've not seen many with this type of preservation and it seems consistent across the skeleton which is good.   I don't think the skull is a composite not based on the images but because it's fairly difficult to do, the bones are very brittle and they are typically distorted and that not what is typically done.   I really don't think you can make a call on the condition of this one based on the photos provided, close examination is needed.   So unfortunately my suggestion is if you're interested go and examine it first hand and make the determination yourself on what you see.

:headscratch:I know it may sound crazy, but taking the negative from the photos has saved me many times from making wrong purchases...
