"Devil Horned" Cyphaspis Walteri Trilobite Cluster

This is a really cool cluster of three complete Cyphaspis walteri trilobites collected near Mrakib, Morocco. This species is sometimes referred to as the "Devil Horn" Cyphaspis for obvious reasons. Two of the specimens are preserved dorsally and one ventral.

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