Rhipidomella penelope brachiopod from the Windom Shale
The other common species of Rhipidomella is R. penelope. It tends to grow larger and have a rounder shell than R. vanuxemi. The specimen below came from the Bay View Coral Bed within the Windom Shale at the Penn Dixie site near Blasdell, NY. It's rare to find a fully inflated specimen and even this one is only partially inflated.
