Submitter notes: Pygidium view: This is the first whole Trilobite I ever found. I was hunting with my daughter Zoe in the old North Quarry on June 23, 2007. This is the only one we found that day with a head. It might also be the last roller that Richard Heimlich ever prepared. The specimen measures 23.7mm x 14.8mm.

Submitter notes: This is a plaster cast of an amazing specimen collected by Jeff Aubry in the late 1970's. It was prepared by Scott Vergiels. This is one of 200 casts made directly from the original by the late Gene Thomas (who was also a great fossil collector and preparer as well). The detail is unusually good for a replica. These were large E. Milleri. The largest is 70 mm. They average about 55 mm. The plate is 310 mm x 230 mm.
