1.5" Kettneraspis Trilobite With Selenite Crystals - Lghaft, Morocco

This is a gorgeous, 1.5" long, Kettneraspis? prescheri trilobite from Morocco. It has a large, and very distinctive occipital spine. The preparation is absolutely fantastic and it only has about 2-3% shell restoration along repaired cracks. Another interesting aspect of this piece is there are selenite crystals present on the limestone it was found in.
