Rostricellula minnesotensis. Seem to be Platteville formation only for me. Easily mistaken for Rhynchotrema wisconsinense until I noticed something odd with my specimens. The sulcus barely exists and sources usually says Rostricellula generally are smaller than Rhynchotrema. Plus the picture I had seen of Zygospira recurvirostris look significant different.
