minnbuckeye Posted April 10, 2021 Share Posted April 10, 2021 My recent trip to the Maquoketa Formation of Iowa produced a brachiopod that baffles me. It appears to have both shells but it is extremely flat. Help needed with ID!!! Mike Link to post Share on other sites
Fossildude19 Posted April 10, 2021 Share Posted April 10, 2021 Strophomenid, maybe Rafinesquina sp? 1 1 Link to post Share on other sites
minnbuckeye Posted April 10, 2021 Author Share Posted April 10, 2021 @Fossildude19, that is what I assumed this was until I realized both valves were there. I have collected Strophomenid from many formations but have never seen one "flattened with a steam roller" on both valves. Link to post Share on other sites
LabRatKing Posted April 10, 2021 Share Posted April 10, 2021 I have a few similar specimens that are very flat from all over the country. I suspect it is more from the pressures of fossilization than original morphology. 1 3 Link to post Share on other sites
