Spirifer
vernonensis Swallow
brachiopod
Mississippian
Fern Glen Formation
St. Louis County, Missouri
This brach is rare because it is complete. One rarely
finds
a complete specimen in the Fern Glen (at least at this locality)
This specimen was found in the "transitional" zone between
the "white" and the "reddish" colored matrix.
Viewer Comments:
Looking through Weller's monograph on Mississippian
brachiopods, it looks like: Spirifer vernonensis Swallow
Of course the name Spirifer is obsolete, so it has
another genus name now.
