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.
