I believe, after some research I have the answer, however I am no expert on this subject. Could you let me know if my answer/ reasoning sounds blatantly wrong to you -
Being that Paleolithic dwelling were typically less permanent structures (ie. temporary wood/bone huts) and that their timeline goes much further back than Neolithic origins I believe this image is of a Permanent Neolithic Dwelling.
My reasoning is that this image resembles another of Excavated dwellings at Skara Brae.(these excavated dwellings that appear so similar are in fact Neolithic structures.)
