Burin

A

Sharp and durable stone tool used in engraving

Used in etching out thin slivers of antler or bone which then were modified further to make awes and needles

Q

Clovis

A

Fluted point type of the Paleoindians

Large, laurel-leaf-shaped stone blades exhibiting a channel or “flute” on both faves to aid in halting the stone point into a wooden shaft

13,200-11,900 ya

Channel begins at base and extends from 1/3 to no more than 1/2 the length of the point

Q

Fluted point

A

Projectile points made by Paleoindians in the New World between 13,200 & 10,000 B.P.

Exhibit distinctive channel or “flute” on both faces, which aid in halting the spear point into its wooden shaft

Major forms are Clovis and Folsom

Q

Folsom

A

Fluted point type of the Paleoindians

Smaller than Clovis

11,000 B.P.

Channels commonly extend nearly the entire length of the point

Q

Microblade

A

Very small stone blade, often with a very sharp cutting edge

Often set in groups into wooden, bone, or antler handles

17
Q

Micronesia

A

Small islands in the western Pacific, east of New Guinea

18
Q

Nenana Complex

A

Perhaps the oldest stone-tool complex identified in Alaska dating from 11,800 to 11,000 B.P.

Includes bifacially flaked, un-fluted spear points

19
Q

Paleoindian

A

Period and culture in the New World dating from about 13,000 to about 10,000 B.P.

Fluted points the most distinctive element I. The Paleoindian stone-tool kit

20
Q

Polynesia

A

Islands of the central and eastern Pacific

21
Q

Pre-Clovis

A

Sites older than Clovis sites, which were formerly believed to be from the first human settlers

22
Q

Sunda (or Sundaland)

A

The combined land mass of the modern islands of Java, Sumatra, Bali, and Borneo

These islands became a single, continuous land mass during periods of glaciation and attendant lowered sea levels during the Pleistocene

23
Q

Sahul

A

The land mass of “Greater Australia” including Australia proper, New Guinea, and Tasmania

During periods of glacial maxima in the Pleistocene these three islands were combined a the single landmass

24
Q

Wallacea

A

Name given to the sea over the Wallace Trench

25
Q

Wallace Trench

A

An undersea chasm located between New Guinea/Australia and Java/Borneo

7,500 m deep (~25,000 ft)

Not breached during periods of lowered Pleistocene sea levels so population movement from Southeast Asia and Sahul were accomplished by a water route

26
Q

Wedge-shaped core

A

Cores shaped like wedges from which blades were struck

Part of the Paleo-Arctic tradition in northeastern Asia & part of the Denali Complex in the American Arctic
