It seems to have some affinities with this one:

More pictures, this time from a mass mortality assemblage. Hope it helps. Thanks in advance.

Yep, i will go with a flexicalymene, but i'm not expert, so wait for more knowlageables' opinions.

Hey Miguel I have no idea what coin you have there unless is a UK £2 (can't see properly as on iPhone). Coins are a bad thing to use as a scale as it's not easy for people from countries other than your own to judge size. Have you got a ruler?  :)

I think there are two valid taxa for the Moroccan Flexicalymene: F. ouzregui and F. tazarinensis (F. tazarensis). Maybe this link would help. :)

Here are the descriptions of Flexicalymene ouzregui & Flexicalymene tazarinensis from Destombes 1966:

Thanks a lot to all, especially to @piranha and @abyssunder.

 

They are F. tazarinensis. They are from near of Omjrane. The matrix is so weird for this genus that almost seems Devonian.

 

Great help - once again -and great reading. I love these weird Phacopids.

 

Best wishes,

 

Miguel

Dimensions:

Worth investing in a geological/paleontological scale. Credit card size, fits in a wallet ;)
