Chapter 8 Flashcards
when are artifact not obviously used by humans
Paleolithic and Lower Paleolithic
Eoliths
pieces of stone found at the beginning of the 20th C in the Lower Pleistocene
what was thought about the shaping of eoliths
they were naturally made
why were eoliths naturally made
there were irregular scars and no bulb formed
what is helpful when examining eoliths
context
why are crude tools harder to distinguish
monkeys have been using tools to crack nuts and leaving cutmarks behind
types of tools found at a site
clues to function
finished tools often turn up in sites
FAR from the stone source
core
the main part of the stone from which the material was removed until the desired shape
primary flake
first flake struck off
have some material of the outer surface or cortex
primary flake
trimming flakes
struck off to achieve the final shape
how can edges of a core be retouched
removing secondary flakes
can the flakes be used as tools too
YES
what does the history of stone tool making show
sporadically increasing degree of refinement over time
first recognizable tool
simple choppers and flakes made from knocking pieces off
microliths
tiny stone tools
Acheulian
evolved over thousands of years
Acheulian period were making
hand-axes
Oldowan industry
earliest stone tools
Oldowan industry had tools like
simple choppers and flakes
Levallois Technique
careful preparation of a core for ONE flake to be used
wasteful and extremely difficult
Levallois technique
upper paleolithic
possible to remove numerous parallel sided blades from a SINGLE stone
blades were retouched to form specialized tools
upper paleolithic
less wasteful way of making tools
upper paleolithic
Chaine Operatoire
sequence of manufacturing steps
a task that would be easier if the knapping was done in one place and ALL the waste material is present
Chain Operatoire
two principal approaches to assessing what decisions the knapper made
- replication
- refitting
refitting of stone tools
attempting to put tools and flakes back together again
a single tool can be used for _______ purposes
many
only direct proof of function is to study
the minute traces of microwear patterns that remain on the original tools
allows to follow the stages of the knapper’s craft and movement around the site
refitting
provides a dynamic POV on the spatial distribution of tools
refitting
even the hardest stones do what
retrain traces of their use
what kind of traces remain on stone
variety of polishes and striations
different kinds of polish are
distinguishable and are very durable
the function of a set of tools
results that can transform our picture of activity at a site
what kind of wear traces are being examined with microwear analysis
- edge flaking
- surface characteristics of polish
- orientation of striations on a stone tool
what did all synthetic materials depend on
the control of heat
first step in developing a new technique and tools was
mastery of fire
pyrotechnology
the control of fire
did the Paleolithic people not know how to make pottery
Not sure, it’s possible
why is there a lack of pottery for the Paleolithic people
they had a mobile life
what does adoption of pottery coincide with
a more stable way of life
temper
the filler incorporated to give added strength and workability
what counteracts cracking or shrinkage during firing
temper
