Can you please try and help identify what these '' ancient stone
tools'' were used for ?? have you ever seen others similar
elsewhere ?? , they seem to occur near mine / quarry sites , and are
named '' Kartan stone tools '' after the aboriginal name of the
island , they are the archaeological production of a large quantity
of exceptionally large stone tools that were first found on Kangaroo
Island a few km off the coast of South Australia.
Kartan culture archaeology presents a puzzle: with a fairly large
offshore island [ 4000 sq km ] without people from the end of the
bronze age until 1800 arrival of European settlers , yet with abundant
evidence of human population over 2500 years ago and back a very long
time before , Lampert wrote a 'The great Kartan mystery '.
Aboriginal stone tool assemblage of Karta have also found on the
nearby South Australian mainland up into the Flinders Ranges 100
km
The tools are very heavy, averaging "perhaps ten times the average
of any other assemblage".Some of the Kartan tools are "horsehoof"
cores, defined as having a "flat base, an overhanging, step-flaked
edge, and a high, domed shape like a horse's hoof"; their function is
unexplained.
Over 120 Kartan sites have been found, yielding thousands of pebble
choppers and hundreds of hammerstones. Most of the Kartan tools from
Kangaroo island itself are composed of Quartzite brought into the
sites , looking like the large tools were almost certainly left over
from some ancient mining activity , as the only real possibility
Few Kartan '' flakes '' / cutting / slicing tools have been found,
but reports of one find by Draper on Kangaroo Island , in a site
dated to 7000 years ago , see pics here ,
