Keichousaurus real?

Recommended Posts

Hi.

I'm looking to buy a Keichousaurus as a present for a collector. I've seen some other threads, but I'm no expert, and so I thought I'd ask here about the specimen I'm interested in.

As a complete novice, this looks "too good to be true" to me, in particular for the price that it's offered. But other threads had similarly looking specimen that were considered genuine.

 

Thanks for the help!

Looks good to me - despite the mostly absent tail. 

Looks like it was acid prepped, to me.

Acid prepped specimen, not very nicely done.  But, look at the abdomen, there are remnants of hatchlings.  This is a gravid female as you know Keichousaurus is ovoviviparious.  Gravid females are quite uncommon.

I see what looks like mechanical damage. I don't think this is entirely acid prepped.

The red area?

And is the shape of the vertebrae within the green area their natural shape or are they ground down?

If it has a good price, that would be a reason to go for it. Despite the preperative issues.

I think both red and green areas look slightly ground down.

Yes, it was also mechanically prepped.  The locals usually use both acid and mechanical means to prep the fossils.

Real, ground down, then acid washed. But crazyhen pointed out something amazing. This is a gravid female, with a bunch of babies in her abdomen, making this a significantly important keichousaurus. I've seen a lot of keichs and never seen one quite like this. Too bad so much detail has already been lost, but this piece needs very good prepping, mostly with a pin vise.

Reference could be made to the gravid female below.  It's in the "natural" form, no prepping was done.  You can see the embryos clearly.
