Kransia pentagona brachiopod from Germany

Kransia pentagona is a small Rhynchonellid type brachiopod from the Hallert mbr. of the Ahbach Formation (Devonian, Givetian stage) near Blankenheim, Germany. It resembles Uncinulus sp. like brachiopods such as Sphaerirhynchia from the Haragan Formation of Oklahoma and Primipilaria primipilaris from Poland.

Thanks to Nils for these specimens.

Subtransnema sp. brachiopod from Germany

Subtransnema sp. brachiopods remind me of Protodouvillina sp. brachiopods. They both look similar in shape and have thin radial lines on the surface of the pedicle valve. The specimen below is from the Hallert member of the Ahbach Formation (Devonian, Givetian stage) near Blankenheim, Germany.

For comparison purposes I've blogged about Douvillina interstrialis from Poland, Douvillina arcuata from Iowa and Protodouvillina inaequistriata from New York and Ontario.

Thanks go out to Nils for sending me this specimen.
