1.5" Kettneraspis Trilobite With Long Occipital & Reedops

This is an excellent, 1.5" long, Kettneraspis? prescheri trilobite from Morocco. It has a large, and very distinctive occipital spine. These trilobites have typically been labeled as Leonaspis but based on more recent papers it appears to be Kettneraspis? prescheri. It's nicely preserved and associated with a curled up Reedops. There is only about 1% restoration on this piece along repaired cracks.
