Foerstephyllum Coral Fossil

A reader recently sent me some images of a colonial coral they found while digging in their yard. It is a Foerstephyllum (Bassler, 1941) coral fossil. It dates to the Ordovician Period and was found in Jefferson County, Kentucky USA.

I have found similar corals in this same area. See these postings:
