Identity HelpPyrite Concretion

8th Aug 2010 00:13 UTCSherman Marsh

I recently acquired this pyrite concretion. It is 4" (10 cm) in diameter and the label says only that "locality where it was found, unknown". This specimen was part of the Philadelphia collection and looks to be old. I can't help but feel that the specimen is so distinctive (I've never seen anything like it) that someone might recognize the form and know the locality (???)

Thanks
