Unknown Devonian Fossil

Here is a fragment of a Devonian fossil found in Clark County, Indiana. It has a pentagon shape on one side and remnants of a series of tube like structures on the other. When I see 5 of something in a fossil, I think crinoid calyx. It is about 2 cm by 2 cm in size and the side with the holes has about 24 openings.
