I am trying to get my fossil collection photographed.  I have more trilobites than anything else, so to light a fire under this ever delayed project, I'm going to post a new bug in my collection each week.   To start off, here is a plate of Primaspis crosotus trilobites from the Kope Formation.  These are itty bitty bugs, but show all the typical Ondotopleurid features -- pleural and pygidal spines all around, and fringes of short spines on the free cheeks.
