Thanks to Nathan for this fossil. Recently, he visited the Louisville area with a group of students from the University of Wisconsin and we exchanged some fossils. They were very dedicated and impressive in their fossil searching capabilities. We visited a number of local sites and collected for hours in the rain, sleet and snow. Brrr, it was cold and wet. Lots of neat fossils were found, including a Silurian cystoid, a spiny brachiopod, trilobite segments, a giant snail, colonial coral colony, and lots of ziplock bags of fossils. After Louisville, they had more areas to visit around the midwest to find fossils at.
