For this week, we have a few examples of Cyperites bicarinatus. These specimens were found in the area around Pit 2. These tapered grass-like leaves were part of the foliage of Carboniferous Period plants like Lepidodenron and Sigilaria. These fossils are pretty common in some of the Mazon Creek localities.
