A somewhat crushed fossil but with excellent growth lines shown in this picture. It appears to be a Tylothyris sp. brachiopod. The Indiana State Museum web site was used for the identification (see link).
Thanks to Alan at the Falls of the Ohio State Park for providing another identification for this fossil. It could be a Punctospirifer subelliptica (McChesney).
This fossil was found in the Borden Formation of the New Providence Shale Member of Clark County Indiana. Brachiopod is dated to the Mississippian Period. Thanks to Kenny for letting me photograph it.
