Brachiopod Identification

[Dave J]

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 👍

These are all brachiopods, not bivalves, although I couldn't tell you which species.

[Brian James Maguire]

Yes these are brachiopods, No1 is a spirifreid

No8 is a rhynchonellida, thats all i can offer you with my limited knowledge

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?

Ok. I'll do smaller groups next time, thank you for the advice. Here's some more pictures of number 5...

Thanks for the extra photos, that's ideaI.  I think this one's Anastrophia deflexa, a rhynchonellid.

Thank you. I'm sorry if I'm being dense but what is rhynchonellid? Is that a family of brachiopod?

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

Thank you. I'm trying to learn. So how is an order different from a species?

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.
