Andesite

The stone specimen previously in the picture is andesite basalt.

The stone tool may have been an isosceles microlith or side

scraper that was worn out and discarded in the throw out.

Andesite has a fine texture and it's coarse grained only

consisting of plagioclase and amphibole.

Another Rim Pottery

Fragment

The pottery shard in the photograph above happens

to be of another rim pottery shard that has another

rim still intact. In fact this particular shard has some

heat temper discolorations also.

Stone Burin

The stone tool specimen in the picture above is

a stone burin. Stone burins have a notch at one end

for cutting and tearing into animal hides. They are

also angled for hand gripping with a downward motion.

Stone burins are considered some of the oldest stone tools.

Stone Chiseling

The stone specimen in the picture above is a

stone chiseling. It may have been a type of scraper or

maybe it's the left over flake remains from a micro

burin of some kind.

Stone File

The stone tool in the picture above is a stone file.

Stone files are larger than modern day files and

the have bigger filing grooves. Stone files were

used with wood workings to remove fine amounts

of materials.

Stone Flake

The stone toll in the picture previously is a stone

flake. It was formed by striking a flake from a stone core.

Stone flakes are tools usually angled or curved for gripping.

Stone knappers have trouble controlling how the stone

will flake and it's also one of the earliest stone tools.

Stone Hammer

The stone tool in the photograph above is a stone hammer.

Most hammers are fastened to a handle and this stone

hammer obviously broke in half when it was last used.

Typical stone tool hammer can be rounded and longer on one end.

Stone hammers are used for pounding, banging, and tapping.

Stone Point Resinated

The stone tool in the picture above is a stone point which

happens to be resonated with plant resins for gripping.

Stone points are used for punching holes in leathers

made from animal hides.

Straight End Scraper

The stone tool in the picture above is a straight

end scraper. Straight end scrapers are used by

scraping with one end. They are formed by chipping

away the end of a flake or stone.

Straight End Scrapers

The stone tools in the photograph above are straight

end scrapers. These particular straight end scrapers

are worn out from scraping on one end. There are a

variety of sizes here.

Swan Tipped Arrowhead

The stone arrowhead in the photograph above is a

swan tipped arrowhead. Swan tipped arrowheads

have no stem point at the base of the arrowhead.

This particular specimen is broken in half and may

have been used as a micro burin because of the

notch at one end.

Thumb Sized Flint Stone

The stone tool in the photograph above happens to be a

thumb sized flint stone. Flint stone are made of microcrystalline

quartz and they are related to agate, amethyst, jasper,

and chalcedony. This particular flint stone is small and

may have been used to sharpen arrowhead and it was

pocket sized to carry around with while hunting.

Top of a Drill Bit Piece

The stone specimen in the photograph above is the

top of a drill bit. Drill bits come in many sizes and

this one was for punching and drilling larger holes

in materials such as leather and other animal hides.

Transverse Point

The stone tool in the photograph previously is a

transverse point. Transverse points or transversal

points are trapezoidal shaped projectile points that

look nothing like what people picture in their minds

an arrowhead to look like. However this particular

specimen is broken in half and may have been

modified into something else.

Trapeze Microlith

The stone tool in the picture above is of a trapeze microlith.

This particular microlith has been retouched or modified

into a trapeze microlith. Microlith is normally made up of

flint or chert. However this specimen is made up of basalt.

Truncated Burin

The stone tool specimen in the picture above is

a truncated burin. This particular specimen is flatter

and smoother. Stone burins have a notch at one end

for cutting and tearing into animal hides. They are

also angled for hand gripping with a downward

motion. Stone burins are considered some of the

oldest stone tools.

Unidentified Bone Fragment

The specimen in the picture above happens to be of an

unidentified bone fragment. This bone fragment was found

near the arrastras. The bone fragment is once again too small

to identify with the osteology of any human or animal bones.

Unidentified Rocks

(Worn out Fish Hooks)

The stone tools found in the picture above appear to be

that of some unidentifiable rocks. However they do seem to appear

similar to some small fragment of fishing hooks that had been

discarded or broken up while in the process of fishing.

War Chuck

The stone tool in the photograph above is of a war chuck.

The rock is hand size and it also has some weight to it.

The stone war chuck also seems to be resinated which

either could be from plant resins for gripping or maybe

it's blood from 2000 years ago.

Wood Saw

The stone tool in the picture above is of a stone wood saw.

This specimen seems to be relatively small like it was used

by a child. There is a steady back edge which would have

been great for gripping. Stone wood saws are used for

chopping, cutting, splitting, sawing, carving through harder

materials such as wood.
