Question 1

Lithics?
(properties? Types of rocks?)

Answer 1

Conchoidal property required (break into predictable manner, silica)

Manuports: rocks tested for conchoidal properties, typically adjusted in a way that is NOT geologically, showcasing human touch.

Core: A flaked manuport

Question 2

Hammer Creation?

Answer 2

Hard: Rocks (<90 degrees)
Soft: Bones (>90 degrees)

Question 3

Flakes?

Answer 3

2 sides: Dorsal + Ventral (flat)

Ventral: 3 Parts (P.M.D) Bottom to Top
Proximal, Mesial, Distal

If there is NO BULB present on a flaked rock, it is NOT a flake!

Bipolarism: flake has two bulbs

Question 4

Platform trimming?
(what is it? 4 types of terminations? Dorsal Cortex?)

Answer 4

Removal of overhanging bits on a rock.

Feather (ideal break)
- Hinge, step, overshoot (wasted)

Dorsal Cortex: shows early depictions of interaction, amount remaining shows how much it was used, looks like a potato!

Question 5

Prepared Core Steps?

Answer 5

1. Radial Reduction
2. Preferential reduction of one side
3. template
4. standardized technique
5. allows for consistency in products final size & shape
6. Produces blanks, that upon retouching become tools.

Question 6

What are blades?

Answer 6

Flakes that are x2 of its own length compared to its width
(if not, it is jus a regular flake)

• can get multiple blades from one core
• broken into a type of lithic called: geometrics

crucially discovered hafting + composite tools (used mastics as ‘glue’)

Question 7

Technological Modes?

Answer 7

Mode 1: Cores + flakes
Mode 2: handaxes + cleavers (acheulean)
Mode 3: Prepared core technology
Mode 4: Blade technology
Mode 5: Microlithic + hafting/composite tools
Mode 6: Ground + polished tools (for grinding)

progression was not linear + no chronological value given to any of these modes
