Mississippian
Fern Glen Formation

St. Louis, Missouri
Preparator: Carl Cook
Preparation time on this specimen was 6 hours. The
specimen
was removed from the matrix and then prepared. The entire
specimen was prepared (not just one side).
Viewer Comments:
The book "Corals of the Chouteau Limestone..."
show
Favosites divergens and Pleurodictyum expansum.
I am not
convinced it is either, but would lean towards it being a
Favosites coral. The Fern Glen is younger than the
Chouteau, but I don't know if there are significant
evolution changes in the corals during that interval.
