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:
