Here is part of an exposed thorax or back of a trilobite. Probably a Flexicalymene meeki since it was found in Ordovician rock at the Bardstown Road cut in June 2008.
One day, if I have the equipment I will try and extract more of the fossil from this rock.
I find that it is a good idea to pick up some rocks that have lots of fossil fragments in them to analyze later. One after cleaning something shows up you did not see in the field and two a recent speaker at a KYANA Geological Society meeting said it is good to have multiple fossils together to help date the fossil.
