2.4" Platyscutellum Trilobite - Rare Type From Atchana

This is a fairly rare and as far as I can determine still undescribed trilobite from Atchana, Morocco. It maybe of the genus Platyscutellum or the genus itself may end up being new. There are several types from this locality, some with bumpy shell, some with axial spines, and some like this one with neither. It's 2.4" long, so it's a fairly good sized specimen and nicely prepared.
