Johnny676767 Posted January 9, 2020 Share Posted January 9, 2020 About two weeks ago, we went to Beltzville State Park in Pennsylvania and found some great Devonian fossils, some of which have been identified with your help. On our way, though, we stopped at a Shell station for air in our tires. There was a small hill of dark grey colored rock (shale?) next to the air pump. My son and I had a quick look. We found what looks like a mussel (pictured here) and something else. I was wondering if it might be a trilobite. Any help is appreciated. I included the location and pic of the hill to help with identification. So, pictures appear like this: location, suspected mussel?, rock for example and then the fossil in question. The picture with the ruler shows the object (circled in succeeding photos). Sorry if this is confusing. Thanks. Lehighton, PA 18235 Link to comment Share on other sites More sharing options...
Kane Posted January 9, 2020 Share Posted January 9, 2020 I would say it is a ventral valve of a brachiopod. 4 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 9, 2020 Share Posted January 9, 2020 Not sure about the first one, but the others seem to be internal and external moulds/ casts of orthid brachiopods. Ordovician or maybe Silurian, I would say. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 9, 2020 Share Posted January 9, 2020 The Beltzville area is Devonian in age, and exposes the Mahantango Formation. First picture looks like the mold of a Pelecypod-bivalve. 2 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Shamalama Posted January 10, 2020 Share Posted January 10, 2020 21 hours ago, Johnny676767 said: That is the brachial valve of either an Ambocoelia umbonata or Emmanuella praeumbonata. Both are known from the Mahantango formation. The Brachial valve is where the brachioles were attached. The two parallel ovalish shapes in the middle of the valve are the parts of the shell where they physically attached. https://viewsofthemahantango.blogspot.com/2014/09/ambocoelia-umbonata-brachiopod-from.html <-- Ambocoelia https://viewsofthemahantango.blogspot.com/2011/12/ambocoelia-umbonata-from-mahantango.html <-- Emmanuella Congrats on finding a new spot on your own as well. It's always a good time checking out road cuts. 1 -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...
