This is an excellent double specimen of Onnia superba from the Ordovician of Morocco. Both trilobites are wonderfully articulated and exhibit exquisite detail. The pitted cephalic borders are totally intact and beautifully displayed. The bulbous glabellas are easily seen, and the long genal spines are quite evident. Even the short, free-standing occipital spines are present. The 3-dimensional trilobites have very good color and contrast. They are nicely presented on the rounded plate of limestone. This is a very striking specimen of two Onnia superba from Morocco.
