Ordovician Trilobite Pygidiums

Here are some Ordovician trilobite pygidiums (or tails) found at the Bardstown Road cut outside of Louisville, Kentucky. They were found in June 2008 during about a 90 minute search.

They are small less than a centimeter across.

I would guess they belonged to Flexicalymene meeki which seemed to be popular in this rock layer.
