The apparent difference in the type of tufo and construction of this block relative to the other ashlar blocks of the original phase (e.g. 7142, 7143, 7158, 7078) makes it unclear whether it belongs to the line of E-W wall 7143/7158/7097. It remains possible that it is actually part of some kind of slab floor. Further exploration is necessary in 2018 to fully understand this space and its organization.
