Wild Looking Proceratocephala Trilobite - Very Rare Species
This is a trilobite that is very rarely seen complete from Morocco, Proceratocephala terribilis. This spiny Odontopleurid trilobite is Late Ordovician in age, where nearly all the other spiny trilobites out of Morocco are Devonian. It comes from the Ktaoua Formation near Tazzarine, Morocco. This specimen is one of the best I've seen. It's good sized at 1.51" long, laid out prone (not curled) and has no restoration. All of the spines on it are real, unlike some examples I've seen for sale in the past. Part of the reason for this is the rock they are found in is really hard and nasty to prepare.
