Onnia superba Moroccan Trilobites Death Assemblage

Onnia superba trilobites

Trilobites Order Asaphida, Family Trinucleidae

Geologic Time: Ordovician

Size: see descritption

Location: Blekos, Morocco

This is SUPERB trilobites death assemblage of a member of the Order Asaphida, Family Trinucleidae from the Ordovician deposits of Blekos, Morocco known as Onnia superba. Cointained within this 6.7 inch by 5.7 inch matrix plaque are TEN examples of the type 0.5 inch - 0.8 inch wide at the genal spines. This is a NATURAL occurence, NOT a composite. There are many fine details present, such as the tiny occipital spine and the fine pitted cephalic rings of the trinucleids. The trinucleids made their living by kicking up detritus from the seafloor, filtering it through the cephalic ring. One wonders what natural catastrophe resulted in the simulataneous death of so many trilobites?
