Trilobites Order Asaphida Suborder Asaphina, Superfamily Trinucleioidea, Family Trinucleidae
Geologic Age: Ordovician
Trilobite is 29 mm long
Blekos, Morocco
Remark: Note the pitted cephalic ring by which the trinucleid trilobites fed by swimming along the seafloor, possibly using their legs to disturb food that then entered their filter chamber with the water exiting dorsally through through the dorsal fenestrae or pits. Notice too the occipital spine coming off the back of the cephalon.
