Pancake or Paper Layer Fossil

This fossil reminds me of stacks of pancakes or layers of paper. I am not sure if it is a coral or a sponge. It was found in a Devonian fossil area in Louisville, Kentucky.











UPDATE: This fossil is a mounding stromatoporoid or calcareous sponge. It probably lived in the Silurian period.

    Stromatolite maybe?

    Thanks for the identification Dave.

    That it what it is after looking for that term and finding this first image on the Kentucky Geological Survey web page: http://www.uky.edu/KGS/fossils/stromatoporoids.htm

    It is a mounding stromatoporoid or calcareous sponge.
