Here is a very interesting multiple plate of trilobites. These are Onnia sp. from the Ordovician of Morocco. This Trinucleid trilobite has a very inflated glabella and a cephalic brim with rows and rows of pits. The genal spines are very long, and there is a short occipital spine emanating from the back of the cephalon. A short, wide triangular pygidium is characteristic of this particular bug. There are eight complete specimens and a large cephalon on this plate. The arthropods are extremely inflated and exhibit wonderful detail. The trilobites have great natural color and contrast extremely well with the sculpted limestone block. This is a very fine multiple display specimen of Onnia trilobites.
