Pyritized Arthroacantha?


Mochaccino

Recommended Posts

Hello,

 

I'm considering this crinoid from the Silica Shale of Ohio, Arthroacantha carpenteri. From what I understand, the unique preservation of this site for these crinoids is a pyritization/pyrite replacement. This specimen seems to have sparkling up close, but it is not apparent from a distance. Does this one indeed seem pyritized? I'd like it if it's a nice, representative example.

 

Thanks.
