Early to Mid Devonian Brachiopods from Spain

Recommended Posts

Hello everyone,

I recently received a lot of 3 brachiopods from Spain.

Here they are with their original labels that they were listed with and that I received them with:

The issue is that when I began to do a bit more research on these species, specifically Hexarhytis the paper that comes up shows and describes a completely different brachiopod. 

Looking up the other Athyrid the results I got were much closer but still not exactly like the brachiopod I have, but since I got more results for this search I could now do a bit of looking into the closely related taxa which I was sure would help me find a match. 

Currently, after that bit of reading I think that the larger brachiopod may be Plicathyris collensis while the smaller one looks more like Anathryis ferronensis to me.

 

Does anyone know if these IDs would be accurate? Are there any papers I could read to better familiarize myself with these species? I wasn't able to find much online but this is the best I could come up with so far.

Additionally, does anyone know how I could identify the species of orthid that is on the left? Researching the other two made me suspicious about the ID for this brachiopod too, it seems that the formation is accurate for this species but there are other orthids present there and I am not sure how to distinguish between them.

I will attach more pictures of all of them below.

The one I believe is actually Plicarthys:

What I believe is Anathyris:

Orthid labelled as Rhipidomella cervantesi:

Thank you!

I’m sorry I can’t help at all with the IDs, I just wanted to say the two “...athyris” are really neat looking and I don’t believe I have seen ones like that before. Especially the larger one, very nice.  The Rhipidomella certainly looks like others of that genus that I am familiar with, but I don’t know anything about the exact species from that formation.

Thank you! I agree these appeared really unique and I didn't have anything like them in my collection which is why I purchased them.

There are some other species in those genera which are much wider and look really interesting as well, almost like spiriferids. These brachiopods are quite interesting

I have been looking at these brachiopods for a bit now, the athyrids I am still not sure about and some parts make me doubt my proposed IDs, for example the one I called Anathyris ferronensis has a narrower area between the two inner ribs than the ones I have been comparing it to online. Its unfortunate that there is so little information available for these brachiopods. 

As for the Orthid I am now thinking that the ID may be accurate, I found a paper online and even though it was in spanish I was able to put together some bits of it along with the pictured brachiopods to determine that Rhipidomella is likely the accurate ID. I was between Rhipidomella cervantesi and Maisorthina saroyani for the ID but after closely comparing them to mine the ribbing on 10 in the second figure appeared much closer.336581924_Screenshot2021-05-039_18_26AM.thumb.png.ecdb7fa85ac98b6316ec4ad0388e3622.png788067288_Screenshot2021-05-039_18_35AM.png.34403d4fec3726f12724c2d139e5fd87.png

I am still not sure about these exactly so if anyone has any info on these brachiopods I would be very interested in finding out more.

Thank you

Interesting stuff, Misha, this formation has a lot of unique species but I don't have much information about it. 

I think your ids are probably correct.

I agree! There are some very interesting brachiopods from there, a while ago but after this was posted I got in touch with that seller and he put together a larger sample of the brachiopods from that formation, there's some really interesting ones there, I'll have to post them some time, maybe to one of my albums which I've been trying to expand recently

Yes, I think you posted several of them on a thread a while back. 

Very nice. :)
