Another of the fossils that Nils sent me as part of our exchange is this Undispirider givefex from the Rodert member of the Cürten Formation (Devonian, Givetian stage) near Sötenich, Germany.
Superficially it resembles and Athryis type brachiopod but there are some minor plications present that help distinguish it.
Specimen #1 Pedicle valve
Specimen #2 Brachial valve
Thanks go out to Nils for these fossils.
