One of the largest of the Devonian period brachiopods a person can find in the limestones of Clark County, Indiana. This specimen appears to be from the Silver Creek layer. One side of the specimen has broken off but the top and bottom sections of the brachiopod appear to be in place. The fossil is a little over 5 cm wide. A matting bryozoan was growing over part of the shell. The engraver should be able to remove matrix on the bottom half of the fossil.
