superba Moroccan Trilobites Death Assemblage
Order Asaphida, Family Trinucleidae
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
