While working on a project taking pictures of Chinese foraminiferas collected in the 1980s, I took a picture of this specimen while the equipment was setup. It is a foram found in the Silurian period Osgood Shale of Ripley County, Indiana. My guess is it might be some sort of Ammodiscus. Dr. James Conkin collected this specimen some years ago. Second image is specimen wet after an attempt to move it with a wet brush.
