Species of Trilobites in Kentucky

One might ask, how many species of trilobites have been found in the state of  Kentucky?

An interesting question, I think I may have fragments of about 7 genera but there are a lot more.

After consulting a book Tracking Trilobites: Adventures in Paleontology by Judy Lundquist, she lists 36 types of trilobite fossils found in Kentucky.  The book is great with pictures/images of about every trilobite listed.  You can find out more at her website: http://home.insightbb.com/~jlq.sci/Judy%20Lundquist.html
