1.15" Harpid Trilobite From Jorf - Rare At Location

This is a 1.15" Harpes perradiatus from Jorf near Erfoud, Morocco. These are pretty rare trilobites at this location and this is one of only a handful of specimens that I've seen. The head is slightly shifted but otherwise the trilobite is well preserved and well prepared.

The rock here is very chert-like with a glassy appearance. The shell is translucent so the trilobites tend to take on the coloration of the underlying rock, leading to very uniquely preserved specimens.
