Spiny Cyphaspis Trilobite Cluster - Top Quality Preparation

This is an exceptional natural association of five complete, spiny Cyphaspis walteri trilobites, accompanied by a ventrally exposed Gerastos, from the Devonian Bou Dib Formation near Mrakib, Morocco. The intricate spines and delicate anatomy of these remarkable trilobites have been meticulously revealed through expert preparation, creating a spectacular, museum-quality display. Total restoration is well under 1%.

Known as the "Devil Horn" Cyphaspis for its dramatic, hornlike spines, this distinctive species was formally described in 2014. This extraordinary multi-specimen plate is a superb collector-grade example of one of Morocco's most iconic spiny trilobites.
