In addition to the initial discovery further artefacts were recovered using seabed sampling techniques and during vessel and wharf monitoring of dredge loads. Recovery locations indicate that the artefacts are not confined to a small, isolated zone of Area 240 but are more widespread. A total of 124 pieces of worked flint were recovered from Area 240 during these activities.

The artefacts were primarily recovered from the Palaeo-Yare floodplain sediments deposited between 200,000 and 250,000 years ago. The worked flint type and condition of the artefacts indicate that they were deposited in different conditions – some are in pristine condition and some are more weathered – but are likely to be associated with the same sediment unit. 
The early Middle Palaeolithic artefacts from Area 240 have survived multiple phases of glaciation and sea level change. The results have shown that submerged landscapes can contain preserved Palaeolithic artefacts and the investigations confirm that the artefacts are not a ‘chance’ find, but indicate clear relationships to submerged and buried landscapes that, although complex, can be examined in detail using a variety of existing fieldwork and analytical methods.
