be more vulnerable to biological degradation. Gribble and shipworm flourish on the Avondster site under excavation, before
it was covered with mesh and sandbags.

Along the Red Sea coast prehistoric shell mounds
and submerged Palaeoshorelines, regularly occur just above the beaches at locations where the sea has eroded a rock shelter. Using these environmental factors as a lead and since during most
of the Pleistocene the sealevel was much lower, a team of researchers tries to locate similar phenomena dating to an earlier period of prehistory under water.
