This fossil is from Guizhou, China.  Any idea what is that?

If I found it here I would assume it was an eroded pyrite cube.

Can we get a close-up of the 'appendage' bits? Also, what age is it?

 

First impression is are an echinoderm - crinoid, for example - preserved with the base of the calyx pointing upwards.

Or maybe the calyx pointing downwards, so the hole at the top would be where the stem was attached. 

I think i see arms snaking away from the end embedded in the matrix.

Sorry, I could not get close-up photos since the fossil is not in my hands.  The local fossil collector got this and I am just curious as to what is that.

Shame - there's no way of telling from these photos, I'm afraid! It'll have to remain a mystery... it's a pity, though, because it could be really interesting!

That's what I said, TD! And yes, that's why I wanted a look at the potential arms as well.  :D

IMO no crinoid: missing pentameric symetric and no hints of typical crinoid segments/segmentation.

Maybe trace-fossil or some soft-tissued animal.

But since Guizhou is a big area with a lot of stratigraphical units, would be good to know more about that.
