Two "Devil Horned" Cyphaspis Walteri Trilobites - Ofaten, Morocco

Here is nice double specimen of Cyphaspis walteri sometimes referred to as the "Devil Horn" Cyphaspis for obvious reasons. The spines are natural and it's been nicely prepared with all of the spines free standing. This is a nicely presented example of this spiny Moroccan Otarionidae trilobite. There is only about 2% restoration along repaired cracks and both specimens are about 1.4" long

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