This is a 4.3" wide cluster of spiny Cyphaspis walteri trilobites collected from the Bou Dib Formation near Mrakib, Morocco. This species is sometimes referred to as the "Devil Horn" Cyphaspis for obvious reasons. There are six complete Cyphaspis along with a single Gerastos Four of the Cyphaspis are preserved ventrally and two are dorsal. Nice preparation on this piece.

This species was finally formally described in 2014. A link to the paper can be found below.
