Dave J Posted June 29 Share Posted June 29 (edited) Hi all. I found these today at the Wren's Nest in Dudley England. I understand that fossils found here are Silurian. I know this may be difficult to do but I was wondering if anyone could offer me any possible species names or other information on these? Anything is greatly appreciated 👍 Edited June 29 by Dave J 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted June 29 Share Posted June 29 These are all brachiopods, not bivalves, although I couldn't tell you which species. 1 3 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Brian James Maguire Posted June 29 Share Posted June 29 Yes these are brachiopods, No1 is a spirifreid No8 is a rhynchonellida, thats all i can offer you with my limited knowledge 1 Link to comment Share on other sites More sharing options...
TqB Posted June 29 Share Posted June 29 I think all or most of nos. 2,3,4,6,7 & 10 are Atrypa reticularis. No. 9 looks like Rhynchotreta cuneata. I think more views are needed of some of them, unless someone knows the fauna really well. Three or four different ones are often helpful, and only, say, two or three specimens per post might get you better answers. ) @Tidgy's Dad? 1 1 1 Tarquin Link to comment Share on other sites More sharing options...

Thanks for the extra photos, that's ideaI. I think this one's Anastrophia deflexa, a rhynchonellid. 1 Tarquin Link to comment Share on other sites More sharing options...

I'm sorry if I'm being dense but what is rhynchonellid? Is that a family of brachiopod? Link to comment Share on other sites More sharing options...

Of course you're not dense, you're just on a learning curve Rhynchonellida is the name of an Order of brachiopods. 1 1 Greetings from the Lake of Constance.

The taxonomic system, for biological organisms is based on shared characteristics, has eight levels in its hierarchy, from lowest to highest, namely: species, genus, family, order, class, phylum, kingdom, domain. The following link explain the system, you can find more information by googling taxonomic system. https://bio.libretexts.org/Courses/Lumen_Learning/Biology_for_Non_Majors_I_(Lumen)/01%3A_Introduction_to_Biology/1.15%3A_Taxonomy#:~:text=The current taxonomic system now,Figure 1.

Tidgy's Dad Posted July 15 Share Posted July 15 1. Lovely specimen of Eospirifer radiatus. 2, 4, 6, 7 and 10. Atrypa reticularis. 3. Could be Isorthis clivosa, but would need a picture of the other valve at least as there are other possible contenders. This specimen also seems to have a specimen of the epibiont Craniops implicata attached. Very nice. 5. I agree with Tarquin that this is Anastrophia deflexa, but @TqB, Anastrophia is an unusual pentamerid, not a rhynchonellid. 8. Is a rhynchonellid, Microsphaeridiorhynchus nucula 9. Rhynchotreta cuneata, another rhynchonellid. Nice finds. 4 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Tis a type of inarticulate brachiopod that lived attached to the shells of other organisms. Usually articulate brachiopods. 1 Life's Good! Tortoise Friend.
