Abstract:
Archaeological finds in general, and bone remains in particular, are exposed in
archaeological sites to various phenomena of damage, which cause distortions and
changes to the surface of the piece and its general shape, and these distortions are
to varying degrees from one piece to another. From this point of view, we thought
that it was necessary to address this aspect of the study and apply it to the
collection of bone art under study, which was extracted from the site of the cave
of Amoura in Djelfa, which dates back to the Holocene period.
We examined this bone group, and concluded that it was subject to various
manifestations of damage, which afflict the bone surface and bone matter in
general, since its abandonment in archaeological sites. It is caused by various
factors, including: Physical and chemical factors (soil oxidation, solid limestone
deposits), and others resulting from biological factors (such as rodents and
carnivores in particular, and plant roots), in addition to the phenomenon of
fragmentation and fracture resulting from natural and human manifestations.
The aim of such a study is to know the extent of human intervention and control
over bone matter, to extract from it the tools that he uses in his daily life, and the
techniques he uses to achieve this
