This is a crinoid fossil from Guizhou, it is attached to a gigantic concretion.  Do you think there is a fossil inside the concretion?  Other than breaking it apart, any other possible way to check if there is a fossil inside the concretion?

I can’t help with the question but that is extremely beautiful!

Happy hunting,

I suppose a CT scan might reveal what's inside the concretion, and it's not destructive. :)

Amazing fossil!

 

Do the concretions in that area usually have fossils inside of them?

It seems no one in the area has broken open the concretions found there, and so I was wondering if it’s worthwhile to ask the fossil collector there to break it apart and check.

Beautiful fossils!

 

How much does one of these crinoid nodules cost? If you were curious enough, you could purchase an ugly and cheap specimen, and break it just to see what's inside.

Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!

They’re exquisite!!! :wub: I’m in fossil love. I don’t say that very lightly. Wow!

Are they 100% real or are they partly restored?

Where can these be found?

They are found in Guizhou, China.  Most of the chinoids are genuine but they tend to make composites for big slab, and there are some crafted ones.  Chinoids of good quality are not uncommon there.

And this is another mysterious but beautiful concretion found at the same area.  You can see some remains of chinoids on the surface but I don’t know if there is something inside.

I understand that it's not cheap considering the size of the nodule :blush:

Can they find broken ones where these were found?

I am not aware of the presence of broken ones found there.

Thats unfortunate, but If they can find ones without crinoids on them they would be good to experiment on.
