This page is not meant to identify my Hermosa trilobites (I have not investigated deep enough yet to arrive at such a conclusion). I'm just including specimens from other documentation here as an example of other, Pennsylvanian trilobites.

Top left is my 'Specimen 1' from the Atokan-Desmoinesian, Hermosa/Pinkerton.
