Recently, I was looking for a trilobite in the Jeffersonville Limestone of Clark County, Indiana USA. I did not find one, at a mostly intact one that is. The best I could do was find this fragment of limestone with part of what is probably a
Phacops rana (Green, 1832) fossilized pygidium. Also seen in this piece of limestone is an unidentified bryozoan fossil. These fossils date to the middle Devonian Period.
