ricardo Posted January 18, 2019 Share Posted January 18, 2019 Dear USA Brachiopoda enthusiasts, Could you see these images please? What is your expert idea about ID? I know that could be difficult from images. Thank you for any help you can offer. 2 Link to comment Share on other sites More sharing options...

erose Posted January 18, 2019 Share Posted January 18, 2019 They all are almost certainly Cincinnetina sp. One of two possible species but formation info needed to better ID to that level. 2 Link to comment Share on other sites More sharing options...

Peat Burns Posted January 18, 2019 Share Posted January 18, 2019 The second one is likely Plaesiomys subquadratus. Agree on the first one: Cincinnetina. 3 Link to comment Share on other sites More sharing options...
