Unidentified Waldron Shale Cystoid Fossil

This posting shows a series of images of a brownish fossil found in the Waldron Shale of Clark County, Indiana, USA.

It could be similar to the Holocystites found in the Silurian aged Osgood Formation limestone. See Kentucky Paleontology Society web site page on some of these fossils.
