Exam 2 Material Flashcards
Nodule
An unworked piece of stone
Core
A worked piece of stone with flakes removed
Knapping
making stone tools by intentionally removing a series of flakes
Lithics
shaped stone artifacts
Pebble cores
Made of rounded clasts (cobbles or pebbles)
Shaped by hard hammer percussion
Choppers - worked edge makes 50-75% of the circumference of the core
Discoids - worked edge makes 75-100% of the core circumference
Bifacial cores
Bilaterally symmetrical with flake removals occurring on both the upper and lower faces of the core
Exhibit unequal length, width, and thickness
Handaxes - at least one sharply pointed end
Thinned bifaces - sharp points at one or both ends
Thickness less than ⅕ of its greatest width
Prepared cores
Display hierarchy of flake release surfaces
One side of the worked edge is used preferentially as a striking platform
Adjacent side - flake release platform
Tools
the intentional product of the manufacturing process
Waste
unused material that results from the process
Debitage
shatter, chips, and debris
Higher artifact diversity ->
Lower residential mobility
High % of cortical flakes ->
Tool production site
High % of retouched tools ->
Activity/habitation area
High % of large cores ->
Close proximity to raw material
Ceramics
made of clay and hardened by heat
Pottery
pots, dishes, containers, and other vessels made of baked clay
Making Pottery
Step 1
Collecting raw materials
Making Pottery
Step 2
Preparing the paste
Making Pottery
Step 3
Shaping the vessel
