Species: Pudoproetus sp.

The hypostome on this specimen is remarkable

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, that was done at Rolla (UMR) I believe
either in the late 50's or early 1960's.

It is probably Pudoproetus fernglenensis (Weller, 1909) which is
found in the Fern Glen Formation, St. Louis County, Missouri.
