Fourth of July Fossil

My cousin Stefano found this pyrite fossil in the Waldron Shale of Clark County, Indiana.  He thought it would make a good July 4th post (American Independence Day) since it was in the shape of a flag flying on a pole.  If I had to guess, it appears to be parts of a crinoid fossil.

As an added bonus the shale plate has part of a Bumastus sp. trilobite cephalon with part of the genial spine. That is a pretty cool find there!

Better view of Bumastus trilobite piece.

Since my cousin is named Stefano I thought it would be appropriate to add a picture of another fossil found in the Waldron shale.  The Coronoidea called Stephanocrinus gemmiformis.
