Q

Why do we Reconstruct Reduction Sequences?

A

If lithic debitage can be matched with the stage of the reduction sequence in which it was produced, we can reconstruction the spatial organization of tool manufacturing, use and reworking

Late/Tertiary Stage Flakes

A

Final stages of tool production – sharpening and resharpening of stone tools
Small
Multifaceted platform, angled lip
Complex scarring on platform; can be complex on dorsal surface but depends on size
Resharpening flakes have use wear on platform

Q

Lithic Raw Materials

A

Better understand the knapping process (including acquisition and stone selection), settlement patterns, seasonal migration, cultural contact, trade networks, economics, and ethnicity
The best raw materials for chipped stone tools are fine grained (micro or crypto crystalline)
Identify raw materials through macroscopic and/or microscopic assessment of characteristics such as color, luster, texture, translucency

Q

Obsidian

A

Extrusive, igneous, fast cooling rock
Volcanic glass
Comes from a number of sources – most common in Alberta are Obsidian Cliff (Wymoning) and Bear Gulch (Idaho), but there are also sources in Oregon (Glass Buttes), British Columbia (Mt. Edziza) and Alaska, among others.
Can be sourced to a specific volcano using XRF analysis
An obsidian flake is sharper than surgical steel

20
Q

Massive Quartz

A

Coarsely crystalline quartz silicate
Large grain/crystal size
Fractures along facets
Multiple sources
Secondary alluvial deposits and glacial tills
Quarries in southern BC and Montana
Banff National Park

21
Q

Knife River Flint

A

Chert silicate formed when silica replaced organic material in a North Dakota peat deposit 30-60 million years ago
Not actually flint (brown chalcedony)
Can have visible plant microfossils
Distinctive white patina with blueish tinge
Fluoresces faint orange under black light
Quarried from secondary deposits in North Dakota’s Dunn and Mercer counties
Widely used on the Plains

22
Q

Swan River Chert

A

Chert silicate which ranges from gray to white and looks like curdled milk
Often heat treated – turns pink

Outcrops in Swan River Valley, west-central Manitoba
Secondary deposits in gravels in alluvial and glacial deposits in southern Saskatchewan and Alberta, at least as far west as Medicine Hat

23
Q

Montana Cherts

A

Chert silicate
Most are yellow/brown in color with black dendrites/inclusions
Avon and Madison Chert are exceptions – white/grey and creamy
Highly variable – come from a number of quarry sources in Montana, most near Helena (a few further west)

27
Q

A

Wood fossilized by replacement of organic material with silica
Cellular structure of the wood often still visible

Relatively common in secondary deposits on the Northwestern Plains

28
Q

  5. DNA analyses
37
Q

  5. Growth increments in teeth, bones, horns and otoliths
38
Q

Why do Archaeologists analyze plant remains?

A

collection, identification, quantification, season of site occupation, processes of plant domestication, status differences between individuals and households, reconstruct past environments

39
Q

Seasonal Availability - Food Plants

A

Spring - greens, shoots, tree bark
Summer - berries, roots, tubers
Fall - nuts, berries, fruits, tubers
Winter - dried fruits, bark
- can also be used for fuel, architecture and medicine

40
Q

Plant Domestication

A

Larger grain/seed, reduced branching, loss/limit of seed dispersal, loss of seed dormancy

41
Q

Bioarchaeologists

A

Specialize in recovery and analysis of human skeletal remains
human osteology
may design and direct archaeological excavations/work as specialists in collaboration with multiple research projects

42
Q

1. Nuchal crest
2. Mastoid Process
3. Supraorbital margin
4. Supraorbital ridge
