Pionodema conradi. I knew I had some tiny orthid brachiopod from Middle Platteville Formation but after checking book and this website: https://2dgf.dk/xpdf/bull26-01-02-115-132.pdf Kind of weird. I think Hesperorthis concava was invalid - too similar and two very close look alike can't compete with each other. One other brachiopod mention on the list Campylorthis deflecta look too much like Strophomena species despite a website saying genus name is valid.
From the album:
Brachiopods of Platteville/Decorah Twin Cities Minnesota
