SU 7375 seems to be bound to 7396, the large tufo block that bisects it, 7291, the northern wall of Room 15 and 7393, the southern wall of Room 15 for the mortar seems to continue and connect between the four SUs, suggesting they are contemporaneous with each other. 7375 also covers 7376, red ashlar blocks found underneath 7375, meaning 7375 is later than 7376.
