As pictured.

Exceptional

Not From mazon Creek formation pit 11. Actually from Indiana Carboniferous. Very close related.

Finally.  The highlight of my collection.  Was on display privately by invitation only . These are ultra rare.( Ill admit bobs is better than mine). Regardless ultra rare . You won't find one from central US coal formation carboniferous. 

.Eoscorpius carbonarius.

Collected in 1969.  This is from Indiana side. Beautiful purple mineralization.

True gem quality fossil.

There might be potential to further prepare the head and front area.

I will consider offers to buy out all remaining  highlights.  This isn't going to be for everyone.

I have seen one or two in private collections. I know no one who would sell one.(or i would have bought them already).  Very rare opportunity.  I don't plan to lower the price much. And I will consider discussing with any interested serious buyers.  If you like it.message me .
