Rock-Guy-17 Posted September 12, 2021 Share Posted September 12, 2021 Have some Mid Devonian brachiopod or bivalve shells that I am not sure about, tried to do some research on my own on what I found. Hoping to get some ID confirmation or help here. Greatly appreciate the help. 7 pictures below: 1. Bivalve Shell? Moscow Formation I believe 2. Brachiopod Shell, never found another like this one? Windom Shale from Livingston Co. Wondering the difference between these two spirifers: 3. 4. 5. Rhipidomella? 6. or is this Rhipidomella? 7. Bonus, cephalopod? gastropod?

Rock-Guy-17 Posted September 12, 2021 Author Share Posted September 12, 2021 Thank you for identifying those. More angles of first two: 1. 2. Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 12, 2021 Share Posted September 12, 2021 1 - looks like a bivalve, but it could be any number of them. They can look fairly similar. Maybe something like Leiopteria conradi. 2 - looks more like a gastropod to me, possible Ruedemannia trilix. However, Mourlonia sp. is another possibility.

Rock-Guy-17 Posted September 12, 2021 Author Share Posted September 12, 2021 I can sort of see the shape of a gastropod for number 2 now, bigger than I thought it would be. Thank you for pointing me in the right direction. Link to comment Share on other sites More sharing options...
Misha Posted September 12, 2021 Share Posted September 12, 2021 Could 1 be a distorted Athyris spiriferoides? And 2 looks more like a Rugose coral than anything to me, would that be possible? 1 1 Link to comment Share on other sites More sharing options...

Usually, I see more black shell like material on Athyris, but it could be. The more oblong shape has me feeling like it's a bivalve, but it could be very distorted. If we could see the inside/back of number 2, it would be helpful. Could be a rugose coral, as well. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

I mentioned later that it could be a rugose coral.

Fossildude19 Posted September 12, 2021 Share Posted September 12, 2021 Having edited the picture of #1, I think it could actually be Meristella sp. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Rock-Guy-17 Posted September 12, 2021 Author Share Posted September 12, 2021 Here are more pictures of 2. I wetted the specimen to expose some more detail Now I can see a horn coral shape too Link to comment Share on other sites More sharing options...
Fossildude19 Posted September 13, 2021 Share Posted September 13, 2021 I would go with Rugose coral for the last one now. Nice catch, @Misha 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."
