Cyphaspis Walteri Trilobite Cluster - Trilobites On Both Sides

This is a really cool 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 trilobites prepared on both sides of the rock, see rotating turn table video.

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