The single-event burial story is a popular elaboration that goes beyond what the evidence can support.

Related to the backfilling question is the question of what was deposited within the fill.

The animal bones, flint tools, and other material in the fill provide information about the activities that took place at the site.

Some of the material in the fill may represent the contents of the enclosures when they were in use — debris from feasting, broken tools, discard from various activities.

The deliberate inclusion of specific items in the fill, if it occurred, could potentially reveal something about the symbolic significance attached to the act of backfilling, but distinguishing deliberate inclusion from incidental accumulation requires careful analysis.
