Hi, @Matthew-Gramling! If you wanted to work together on IDing this further, I’ve read that getting a closer look at the individual zooids is the best way.

Greetings @samantha-ocon! That sounds excellent! If I can obtain a magnified shot of the zooids I will upload it to the specimen file. I believe they are fenestrate bryozoans. I have been in contact with Dr. Timothy Chowns, who is professor emeritus of geology at University of West Georgia. His primary field is sedimentary petrology and he has done considerable work on the strata of Georgia’s Valley and Ridge and Appalachian Plateau physiographic provinces, especially the Red Mountain Formation of northwest Georgia and eastern Alabama. He believes that most of the specimens I have collected are from the grey shales from the Ruffner and possibly Birmingham members of the Red Mountain Formation. The rugose corals are possibly associated with the Duck Springs or Taylor Ridge members.

@Matthew-Gramling, thank you so much for the info! I really appreciate your uploads for the amount of information you document and the quality of data you include. Keep me in the loop as you learn more about your specimens so we can work to improve their eMuseum entries.

@samantha-ocon Thnank you for the compliment and all your help in narrowing down IDs for my specimens! I’ll be sure to keep in touch as I find out more.
