I'm working with Dr David Campbell on possible fossils found associated with the Murphy Marble Fm in Western North Carolina. In 1973. Don Hathaway was logging cores at the Nantahala Limestone Quarry when he found what looked to be organic remains in a couple of cores cut into the Murphy Marble Fm. The age of the Murphy Marble is enigmatic, because of the lack of fossils in it, and it doesn't have the minerals that could be used to determine radiometric ages. The metamorphic grade of the marble and associated formations are garnet to staurolite grade. It's believed that these units were metamorposed during the middle or late Paleozoic. Unfortunately we couldn't handle the cores, and we were only allowed to photograph them. Since neither of us hasn't done research on brachipods before we are looking for opinions on the of these apparent organic remains. I almost forgot to mention that these fossils were apparently in an unit above the Murphy Marble Fm in the base of the overlying Mineral Bluff Group. I didn't take the photos so I don't have a scale for them. I finally did dig up a old picture from a talk given back in 2019 at a NCFC meeting in Raleigh and got a screenshot of part of the article to give you an idea of the scale on these pics.
