Archaeological Evidence: Preservation and Formation Processes, Study notes of Social Anthropology

This chapter explores the basic categories of archaeological evidence, including artifacts, ecofacts, features, and structures. It also discusses context, taphonomy, and the difference between cultural and natural formation processes. Various preservation methods and the impact of climate and natural disasters on archaeological sites.

Chapter 2:
- Basic Categories of archaeological evidence:
+, Artifacts: Objects used, modified, or made by people
+, Ecofacts: Organic and environmental remains (human skeletons, animal bones, plant
remains, soils and sediments)
+, Features: All humanly modified components of a site or landscape (postholes, hearths,
storage pits, etc)
+, Structures: Buildings of all kinds
- Context:
+, Matrix: the material surrounding it, usually some sort of sediment (gravel, sand and
clay)
+, Provenience: Horizontal and vertical position within the matrix
+, Association: Occurrence together with other archaeological remains, usually in the
same matrix
- Taphonomy: The study of the effect of formation processes on finds came to be buried
and what happened to them after they were buried
- Cultural formation processes vs natural formation processes:
+, Cultural: the deliberate or accidental activities of human beings as they make or use
artifacts, build or abandon buildings, plow their fields, etc
+, Natural: natural events that govern both the burial and the survival of the
archaeological record
โ†’ Important to know whether certain archaeological evidence is the product of human or
non-human activity
- Experimental archaeology: the study of past behavioral processes by testing hypotheses
by replicating processes from the past.
1/ Cultural formation processes:
- Two kinds:
+, Reflect the original human behavior and activity before a find or site became buried
+, Those that came after burial
- Original human behavior is often reflected archaeologically in at least four major
activities - in case of a tool:
+, Acquisition of the raw material
+, Manufacture
+, Use (and distribution)
+, Disposal or discard when the tool is worn out or broken
In case of food crop:
+, Acquired (harvested)
+, Manufactured (processed)
+, Used (eaten)
+, Discarded (digested and the waste products excreted)

  • Experimental archaeology: the study of past behavioral processes by testing hypotheses by replicating processes from the past. 1/ Cultural formation processes:
  • Two kinds: +, Reflect the original human behavior and activity before a find or site became buried +, Those that came after burial
  • Original human behavior is often reflected archaeologically in at least four major activities - in case of a tool: +, Acquisition of the raw material +, Manufacture +, Use (and distribution) +, Disposal or discard when the tool is worn out or broken In case of food crop: +, Acquired (harvested) +, Manufactured (processed) +, Used (eaten) +, Discarded (digested and the waste products excreted)
  • Might add storage before use
  • Some human destruction sometimes has turned out to preserve material for the archaeologist to find: +, Burning: can improve the chances of survival of a variety of remains, such as of plants: the conversion into carbon greatly increases the powers of resistance to the ravages of time. +, Clay after being fired 2/ Natural formation processes: a) Inorganic material:
  • Stone, clay and metals (gold, silver and lead)
  • Electrolysis: Placing the object in a chemical solution and passing a weak current through it โ†’ Leaves metal artifact clean and safe b) Organic material:
  • Determined largely by the matrix and by climate
  • Matrix: +, Starunia, Ukraine: Wooly rhinoceros preserved by a combination of salt and oil +, La Brea, Los Angeles: Asphalt pits are famous for the large quantities and fine condition of the skeletons of a wide range of prehistoric animals and birds
  • Climate: +, Caves +, Tropical climates are the most destructive (heavy rains, acid soils, warm temperatures, high humidity, erosion and wealth of vegetation and insect life) +, Jungle condition can be positive: hide looters from easily reaching +, Temperate climates (Europe and North America) not good: relatively warm but variable temperatures and fluctuating rainfall combine to accelerate the processes of decay. +, Natural disasters sometimes preserve sites: violent storms (the one covered the coastal Neolithic village of Skara Brae, in the Orkney Islands, off the north coast of Scotland with sand), mudslide (prehistoric village of Ozette), volcanic eruptions (Vesuvius - Pompeii)
  • Preservation: Extreme conditions: +, Dry environments โ— Prevents decay through the shortage of water โ— First became aware in Egypt โ— Pueblo dwellers of the American Southwest (C.700-1400CE) โ— Danger Cave, Utah (9000 BCE onward): wooden arrows, trap springs, knife handles and other wooden tools โ— Caves near Durango, Colorado: Maize cobs, squashes, sunflower and mustard seeds) โ†’ Reconstruct ancient diet โ— Coastal dwellers of central and southern Peru
