Consider the following statements regarding the identification of Lower Paleolithic sites:
- The concentration of artifacts along ancient river systems may reflect both human preference for resource-rich environments and the subsequent role of fluvial processes in preserving archaeological material.
- River terraces are valuable archaeological contexts because their stratigraphic position can help relate artifacts to former phases of river development.
- The discovery of stone tools within a gravel deposit necessarily proves that the artifacts were manufactured at that location.
- The presence of suitable raw materials such as quartzite or chert near an archaeological site can help explain tool-making activity, but does not by itself establish that the recovered tools were made from those specific sources.
Consider the following statements about Lower Paleolithic landscapes and archaeological interpretation:
- Caves and rock shelters are archaeologically significant because repeated occupation can produce stratified deposits containing tools, animal remains and other traces of activity.
- Open-air Lower Paleolithic sites are of limited archaeological value because the absence of a protective roof generally prevents meaningful preservation of artifacts.
- Geological analysis is important in Lower Paleolithic archaeology because artifacts may have been transported, buried or displaced by natural sedimentary processes.
- The identification of ancient stone-working areas can provide evidence of technological activity even when there is little evidence for prolonged residential occupation.
