historianmichael Posted February 9, 2022 Share Posted February 9, 2022 Over the winter holidays I visited a couple of exposures of the Mississippian (Chesterian) Bangor Limestone in Alabama. I found a ton of really cool fossils, including a number of brachiopods. I was able to identify the vast majority of the brachiopods I found, but I struggled to identify the following. Does anyone recognize them? #3 and #4 look to me to be Composita sp. but the only species of Composita from the Bangor Limestone that I saw is Composita subquadrata and these did not seem to match. Any help would be greatly appreciated! #1 #2 #3 #4 #5 2 Follow me on Instagram (@fossil_mike) to check out my personal collection of fossils collected and acquired over more than 15 years of fossil hunting!

connorp Posted February 9, 2022 Share Posted February 9, 2022 I would check out Cleiothyridina. Could be a match for some of those. #4 looks like Composita to me. 1 Link to comment Share on other sites More sharing options...

I agree that #5 is probably Cleiothyridina sublamellosa, but the photos that I found show heavy banding that is not present in the other ones. What makes you think that the others are Cleiothyridina?

What makes you think that the others are Cleiothyridina? I am not very familiar with Mississippian brachs, that was just the genus that first popped into mind. Maybe @Tidgy's Dad will have some insights. 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 9, 2022 Share Posted February 9, 2022 (edited) Difficult having only two views of each specimen and no scale. 1. Looks like Rhipidomella to me. Don't know the species present in this formation. 2. Hmmmm.Cleiothyridina is closest, can't think of anything better. 3. Girtyella sp? 4. Beecheria sp. Or Composita subquadrata. 5. Cleiothyridina sublamellosa. Edited February 10, 2022 by Tidgy's Dad 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
