Res Ipsa Posted August 29, 2015 Share Posted August 29, 2015 When I was a young rockhound back in the early 70s, I joined the Hamilton (Ontario) Geological Society. One field trip was to a newly blasted out excavation in Nanticoke, I believe for the then new hydro power plant or possibly associated with the steel works. I recall that it was a one off opportunity before the pit was flooded forever. I found what I was told was the specimen of the trip, but it was in a huge slab and I did not expect to be leaving with it. The old guys had other ideas, and I fondly remember several sledgehammers in action before my prize was liberated. I have always wanted to know more about it.

Ludwigia Posted August 29, 2015 Share Posted August 29, 2015 Looks to me like the negative mold plus a bit of leftover shell from the Ordovician brachiopod Rafinesquina sp. https://www.google.de/search?q=rafinesquina&source=lnms&tbm=isch&sa=X&ved=0CAcQ_AUoAWoVChMIrvncxdnNxwIVxvByCh2Mog4d&biw=1600&bih=766 1 Greetings from the Lake of Constance.

bethk Posted August 31, 2015 Share Posted August 31, 2015 The area of Nanticoke is Devonian, but it appears that Rafesquina sp was around from the Ordovician through to the Devonian so it could well be this species. A nice find! Link to comment Share on other sites More sharing options...
