Brach3 posted a topic in General Fossil Discussion
Dear all, if Devonian Epizoans (Epibionts) & Pathological Brachiopods (all the periods) are a fascinating group of fossils for you and you want to discuss anything about their paleoecology, please post your photos (specimens) in this thread.- 225 replies

I was summoned back to Ohio the first week of May to present my niece with her White Coat at THE Ohio State College of Veterinary Medicine. It was nice to return to my alma mater, if only for a day. But when I had arranged this trip, I had scheduled a few fossil sites to visit on the way. Permission had been granted, which is tough to receive. But the weather did NOT cooperate. I can hunt in rain, but not when it is a downpour. So as I was leaving Columbus for home, I thought maybe I could indulge my fossil desires by checking out a few road cuts as I passed by. Again, each of my choices was rained out. Dejected and tired, I listened to the monotonous sound from the windshield wipers, as I drove down the highway. Then surprisingly, the rain let up. Looking at the radar, I felt it would stay dry for about an hour. So next came Google Earth in attempts to find a nearby road cut. Success was had and only 5 miles off my intended route. This site provided many fossils to choose from, but 80% of them carried ethier epibionts or attachments of coral and bryozoans after they had died, often times covering the fossil. First a few of the rare "clean" fossils from what I concluded was the Whitewater Member of the Ordovician. This was a suprise to me. I never have found a Bellerophon like fossil in the Ordovician this large. This was my favorite bivalve: Bryozoans were abundant: Gastropods were not : These were common, but I am in need of an ID: Two types of rugosa coral were found: Vinlandostrophia were the most common brachiopod found but rarely loose from its matrix. Why would this be so smooth? Just water worn???? Not even a hint of a rib! Yet it sits next to one with distinct ribbing. But as I said, "epibionts" created a "problem" if one is looking for pristeen fossils. I, for one, like epibionts or attachments of other organisms. So I was in heaven!! I will explore this site again sometime. Here are Rafinesquina covered with Protarea richmondensis. This fossil was covered to the point of not identifiable. Now my favorite: Nothing too special, but it made my drive home more enjoyable, knowing I came away with at least a few keepers!! Mike
