I visited a coal mine last weekend with a group, and we had a good time finding Carboniferous era fossils.  There were large volumes of plant fossils.  I did find a few marine fossils (brachiopods) also.  I found the "thing" below as well, which mystified me.  I found it splitting a rock, and there was a counterpart as well. I did not retain the counterpart, perhaps I should have (it was broken).

 

Formation:  Pottsville Group
Age:  Pennsylvanian Period, Westphalian-A (312 million years old)

.Jefferson County, AL

 

Anyone know what this might be?

Although I favor Connor's ID, ... if marine fossils were found as well, it could be a worn impression of a crinoid columnal from Platycrinites.

EDIT: What is the size of this?

The white 'film' looks like it might be degraded pyrite. If it is, then vegetation might be suggested. The rock looks like it has gone through a little metamorphosis...
