1.75" Kettneraspis Trilobite With Long Occipital - Lghaft, Morocco

This is a large, 1.75" 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. This specimen is very large for the species.
