Subretepora asperato-striata Bryozoan

While researching some Waldron Shale fossil identifications for members of the Fossil Forum, I came across this little gem. When I began collecting about 4 years ago, this is one of the first fossils I found.  It is from the Waldron Shale of Clark County, Indiana.  This Middle Silurian Period specimen is actually two fossils of distinction: the side not shown is a Favosites colony and the visible side is a little branching bryozoan.  The bryozoan appears to be a Subretepora asperato-striata as seen on this web site: http://bingweb.binghamton.edu/~kwilson/Silurian/RochesterShale/RSCorBry.htm
