Trilobite Onnia Trilobite Plate

This is a plate with three well preserved and well prepared Onnia trilobites from Blekos, Morocco. They are similar to the species Onnia superba, but this one is likely undescribed. The pitted cephalic ring is well preserved as well as the distinctive long genal spines that expend out past it's tail. The occipital spine has been prepared free-standing, a sign of good quality preparation.
