They say that these told that were found identified
three types of bone retouchers, known as soft
hammers, that were used to modify stone tools. The
first type was weathered limb bone fragments, mainly
from the species of any member of the deer family,
marginally shaped by retouching and intensively
used on a single area. The second type was long
limb bone flakes resulting from the dismemberment
of large mammals, used for quick retouching or
resharpening of stone tools. And the third type was a
single specimen of an horn of an deer that, close to
its tip, shows impact scars produced by percussing
various animals
The tools or artifacts represent that they used to use
bones as raw material to modify stone tools. The
researchers have not yet determined which species
the users of these prehistoric tools belonged to,
although they do know that they lived during the
same period as theHomo sapiens. They have found
these tools at an East Asian sidem that means that
their discovery gives China an opportunity to be
compared with the artifacts on a global scale.
