Very Rare Tropidocoryphe Trilobite - Proetid With Axial Spines

This is a very rare type of Proetid trilobite from the Lhandar Formation of Morocco. It bears a lot of characteristics with the commonly seen Cornuproetus but it has axial spines. This would seem to match the genus Tropidocoryphe described in 2009. I've only seen one other example of this species. While the right cheek is displaced on this specimen the preparation is excellent. As an added bonus several micro fossils (gastropods or ammonoides) can be seen in the surrounding limestone.
