This is an excellent triple specimen of Onnia superba from the Ordovician of Morocco. All three trilobites are wonderfully articulated and exhibit great detail. The pitted cephalic borders are clearly defined, the bulbous glabellas are nicely preserved, and the long, slender genal spines are easily seen. The three-dimensional bugs have wonderful natural color and are beautifully showcased on the sculpted plate of matrix (one bug is partially laying on top of another bug - quite cool!) And best of all, this is a natural triple - the trilobites have NOT been composited. This is a very collectible and displayable multiple specimen of Onnia from North Africa.
