This past April I took a trip through Virginia and West Virginia exploring some sites that were listed in the book "Fossil Collecting in the Mid-Atlantic States" by Jasper Burns. One of the more productive sites was in the Licking Creek formation, which is lower Devonian in age (Lockhovian to Pragian stage), where all the fossils were replaced by quartz and could be found eroded loose out of the rock.
I only found a couple of pieces of Favosites type coral at the site, and I think they can be called Favosites conicus.
Specimen #1, this is the base or bottom of the specimen
Specimen #2, Top. This could be a different species but I don't know for sure.
A specimen of Favosites conicus from the Yale Peabody collection.
All of the above specimens came from a roadcut along US route 220 in Highland county, Virginia. The cut is listed as site #16 in the book "Fossil Collecting in the Mid-Atlantic States" by Jasper Burns. The Licking Creek formation is equivalent to the Shriver Chert member of the Old Port formation in Pennsylvania and the Birdsong formation in Tennessee which means that the fossils are part of the Helderbergian fauna.
