This next brachiopod is Primipilaria primipilaris (Uncinulus primipilaris) from the Skaly beds in Poland. It really stands out to me because, in the anterior view, the edges of the shells where they meet always look like they are puckered from eating a sour lemon drop.
Here is another specime's anterior and profile view to further show the puckered look.
Both specimens came from the Skaly beds near Kielce, Poland. They are from the middle Devonian, Eifelian to Givetian stages.
