An excellent and substantial geode fossil of one of Morocco's most well known trilobites. The carapace prone across the metamorphosed limestone which has been split to reveal the individual, its inflated glabella and bulbous eyes protrude up from the silts of time where the negative impression of the exoskeleton is mirrored in the opposing half of the geode stone.

A great first time or further study fossil from this renowned stable for the diacalymene specimens. Discovered in the Sahara desert of North Africa, among the hamada and rocks, the now dry ténéré, once an ocean covering the globe.
