Mochaccino Posted July 31, 2022 Share Posted July 31, 2022 Hello, Can anyone help me ID this brachiopod? It small at 2cm across. Unfortunately I don't have any precise locality info on it, but based on the fossils I bought it with it may be Mississippian aged from Gilmore City, Iowa or LeGrand, Iowa...

Thomas.Dodson Posted July 31, 2022 Share Posted July 31, 2022 A Rhynchonellid perhaps? Unfortunately it will be difficult or impossible to reliably identify this to a low taxonomic level without stratigraphic/locality information. @Tidgy's Dad may have some input. 1 2 Link to comment Share on other sites More sharing options...

I thought that might be the case, thanks! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted August 1, 2022 Share Posted August 1, 2022 It looks sort of Cretaceousy to me, but as @Thomas.Dodson has said, it's really not possible to guess, I'm afraid. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

It seems akin to mesozoic rhynchonellids, but as both prior have said, it is impossible unfortunately. I'm comparing with Tetrarhynchiidae. ~ Isaac; www.isaactfm.com "Don't move!

I'm comparing with Tetrarhynchiidae. From some searching I do see a resemblance but brachiopods are probably so widespread and variable in the fossil record, so I guess indeed difficult as you said. I bought the fossil as a batch so I'll see if I can use the others to narrow down. Thanks. Link to comment Share on other sites More sharing options...
