Thanks to Dr. Bruce L. Stinchcomb for identifying the Genus
Your trilobite is a species of the genus Pudoproetus.
I don't recall the species. It is, of course, as you mention
a member of the family Proetidae. There is a Fern Glen
masters thesis, was done at Rolla (UMR) I believe either
in the late 50's or early 1960's.
