Making time: 'Living floors', 'palimpsests' and site formation processes - A perspective from the open-air Lower Paleolithic site of Revadim Quarry, Israel

The recognition of the dynamic role of site formation processes led archaeologists to recognize a behavioral dichotomy between 'living floors' and palimpsests', Yet the archaeological proxies of 'living floor' and 'palimpsest' were never defined formally, and therefore have been used variably. We use archaeological criteria mentioned in the archaeological literature to model types of formation processes. The case study of the Lower Paleolithic open-air site of Revadim Quarry, Israel is used to test the model. Two types of palimpsests, differing in the rate of accumulation and thus in their effects on the anthropogenic remains, were discerned. Based on these results we review some other Lower Paleolithic instances. A sliding scale of formation processes provides a much needed middle ground between the scales of coarse, time-averaged formation processes and short, "near real-life" behavioral episodes and is an appropriate archaeological frame of reference.
