Spiny "Devil-Horned" Cyphaspis Trilobite Cluster - Mrakib, Morocco

This is an extraordinary natural association of three spiny Cyphaspis walteri trilobites from the Devonian Bou Dib Formation near Mrakib, Morocco. The intricate spines and distinctive anatomy of each trilobite have been meticulously revealed through expert preparation. Total restoration is approximately 2%, confined to areas along repaired cracks.

Often referred to as the "Devil Horn" Cyphaspis, this remarkable species is celebrated for its prominent, hornlike spines and striking appearance. Although known to collectors for years, Cyphaspis walteri was not formally described until 2014. This impressive multi-specimen association is a superb collector-grade display of one of Morocco's most distinctive spiny trilobites.
