Here is a very beautiful multiple plate of professionally-prepared trilobites. These bugs are Onnia superba from the Ordovician Ktaoua Limestone of Morocco. This Trinucleid trilobite has a very inflated glabella and a cephalic brim with rows and rows of pits. The genal spines are extremely long, and there is a long occipital spine emanating from the back of the cephalon. A very short, wide triangular pygidium is characteristic of this particular trilobite.

There are three wonderfully detailed specimens on this plate. All three bugs have their occipital spines prepared free-standing. The distinct trilobites are quite inflated and 3-D. The trilobites have great natural color and contrast extremely well with the light-colored matrix. The fossils are aesthetically spaced (natural, no compositing) on the sculpted limestone block. This is a great multiple display plate of the classic Ordovician trilobite, Onnia superba.
