Arch. Final Section I Flashcards
exposure of remains via controlled digging
excavation
what is the goal of control in excavation?
to reconstruct everything and see how they fit together in space
what does excavation tell us? (2) (HW)
1) how are sites created?
2) what are they composed of?
layers represent activities and deposit (cultural and natural) from different time periods
STRATA
sequence of strata built up in layers
stratigraphy
in an undisturbed stratigraphic sequence each layer (strata) is younger than the layer beneath
law of superposition
problems with the law of superposition (2) (WM)
1) wall can be built on top of older strata
2) making sense of what you’re digging during excavation is most challenging
types of controlled excavation
1) grids (horizontal)
2) datum points (vertical)
what do horizontal excavation rep?
activities at any point in time
what does vertical excavations rep?
a single fixed point that all depth points are taken from (how the site has changed)
goals of excavation
1) identify strata
2) recover remains
3) reconstruct horizontal (same) and vertical (through time) relationships
excavation techniques
1) digging (axes, trowels, picks)
2) brushing
3) screening- put dirt through screens and find artifacts
4) flotation (stones will sink and bones and artifacts will float)
excavation strategies
1) horizontal excavation (remains from the same period)
2) vertical excavation (remains from successive time periods)
excavated materials (3)
1) artifacts
2) features
3) ecofacts
evidence of human manufacture
artifacts
non-portable cultural items (buildings, monuments, burials)
features
remains of biological organisms (human bones, animals, seeds, wood)
ecofacts
what type of material is a mammoth foot bone that is craved into a flute and why?
an artifact because it was modified
documentation techinques (4) (NPDD)
1) notes and forms
2) photographs
3) drawing and maps
4) digitization
what is the goal of documentation?
rconstruction of remains in context
the significance of remains interpreted based on where they were deposited (provenience) and what they were deposited with (association)
context
chronology based on stratragraphic sequences. not sure of the actual date.
relative dating
relative frequencies through time
seriation
dating contexts and artifacts in calendar years via scientific tests
absolute chronology
what type of dating technique is radio carbon dating?
absolute
what does radiocarbon dating measure?
how long it has been since something organic died (must have once been alive)
measurement of the rate of decay of the radioactive (unstable) carbon isotope C14 from dead plant/animal remains
radioactive carbon dating
when someone dies do they continue to take in C14?
no but it continues in body until its decayed
how long does all the decay take to leave the body?
40,000 years
what does the three age system consist of?
stone age, bronze and iron age
what was the three age system rooted in and what was its focus?
rooted in technology and focused on artifacts
who is associated with the three age system?
Christian Jurgensen Thompsen 1816
characteristics of culture history (4) (CDDM)
1) classifies “culture areas”
2) development over time
3) descriptive
4) material culture (pots=people)
geographic location with lots of remains
culture areas
characteristics of V. Gordon Childe
1) neolithic revolution
2) urban revolution
settled life and beginnings of agriculture
neolithic revolution
cities and complex gov’t
urban revolution
what else was proccesualism also known as?
“The New Archaeology”
who was part of processualism?
American Graduate students (1970) that rejected descriptive approach of culture historians
what was archeology seen as in processualism?
archaeology as science
how was processualism tested?
1) hypothesis testing
2) scientific method
what did Lewis Binford do?
search for universal laws and processes
what does culture represent according to Lewis Binford?
adaption to the environment
what type of approach did Binford take?
Etic
objectiv , outsiders view of culture
etic
when did post processualism occur?
1980s-1990s
charactersitics of post-processualism? (3) (BAP)
1) backlash against processualism (culture history)
2) archaeological excavation not replicable
3) positivism too objective
what approach does arcchaeology take in post processualism?
more like history than science (remains in text)
prespective “the insiders view” of their own culture
Emic
types of hominin species
1) sahelanthropus tchadensis
2) australopithecus
3) homo habilis & homo erectus
4) homo naledi
what was the earliest hominin?
sahelanthropus tchandensis
when and where was sahelanthropus tchandensis from?
7 mya, chad
