Tetradium

Rare nearly intact Rafinesquina trentonensis. I myself are surprised I hadn't broken it yet. Decorah Formation, Ordovician, Twin Cities Minnesota. Another surprise is it have parts of its other half of shell still attached. Very thin thus most intact specimens are usually in rock slabs not this complete out of the shale.
