StephLeigh Posted January 9, 2017 Share Posted January 9, 2017 I have collected lots of coral from southwest South Dakota. I believe the majority is horn coral. Despite having a few publications and checking the web, I have several I'm not sure of. A lot of what I find looks agatized. I have attached a photo of what I am guessing is chaetetes coral? Would ove some input. If if someone can suggest a listing of Fossil coral, sponges and Bryozoans with detailed photos or identification, I'd appreciate it. I feel like I have an idea on most of it, just not 100%. Many Thanks! Link to comment Share on other sites More sharing options...

Ramon Posted January 9, 2017 Share Posted January 9, 2017 It looks like one. It might be or a similar taxa. But, I am no expert. We really need someone else to answer.

Referring to the photo with the penny; I'm not sure there is a clear enough view of the pattern to tell if that is what this is. It could easily be a tabulate. The larger piece on the right looks more like a mineral to me. Link to comment Share on other sites More sharing options...
