Abstract
Lithic points have always been assumed to have been spears and they occur in Middle Stone Age
(MSA) assemblages in great numbers before the Howiesons Poort. They disappear or occur only
very rarely in the Howiesons Poort Industry (when segments appear to replace them). After the
Howiesons Poort, points become common again. Segments, which are part of some Later Stone
Age (LSA), as well as MSA assemblages, have, like points, been associated with hunting
weapons. This study reports on the results of a technological analysis of South African points
and segments. The points come from two MSA sites in KwaZulu-Natal: Sibudu Cave and
Umhlatuzana Rock Shelter. MSA segments are from the Howiesons Poort assemblages of
Sibudu and Umhlatuzana, while LSA segments are from Jubilee Shelter in the Magaliesberg.
Changing hunting strategies are examined through time by investigating the changing
technologies used for points and segments. This is a new contribution because no-one has ever
used the same methodology to compare segments and points.
Sibudu and Umhlatuzana points cover a long span of time. Sibudu points come from layers that
have optically stimulated luminescence ages of between ~73,000 – ~35,000 years ago and they
include specimens from the Still Bay up to the final MSA. Radiocarbon ages from Umhlatuzana
may be unreliable because they are likely to be minimum ages and because of rotational slippage
of some of the sediments. MSA segments from Sibudu have an age of approximately 70,000 –
60,000 years ago while LSA segments from Jubilee have an age of about 6,000 years ago.
There is overwhelming evidence that points from Sibudu and Umhlatuzana were used as hafted
spearheads. Results of morphometric analyses, tip cross-sectional area (TCSA) and tip
penetrating angles support Marlize Lombard’s suggestion (based on use-trace analyses) that
post-Howiesons Poort points from Sibudu were used as hafted hand-held spears while Still Bay
points served several purposes which included hunting. Similar results were obtained from the
analysis of Umhlatuzana points. Changes in the use of points over time are not as evident at
Umhlatuzana as at Sibudu, but the morphologies of their bases suggest that final MSA points iii
were hafted differently from points in the older MSA phases. Rock types appear not to have
played any role in the form and function of points from the two sites.
Sibudu and Umhlatuzana segments are likely to have been used to tip different types of hunting
weapons. Their size attributes, TCSA and tip penetrating angles are within the range of attributes
of other MSA segments (from other South African contexts), some of which have been
suggested to have been used as hunting weapons. When hafted vertically, transversely or
diagonally, they are likely to have been used as arrowheads and when hafted in pairs (back-toback),
they could have been used as darts, or even spearheads in the case of large segments.
Results of the Sibudu and Umhlatuzana technological analyses of segments confirm results of
residue analysis and experimental work. These indicate that segments could have been hafted in
various configurations, but that they were used mainly to tip hunting weapons. Jubilee Shelter
LSA segments are, however, probably too small to have been used effectively as hunting tools
(especially if hafted vertically and diagonally) and micro-wear analysis by Wadley and
Binneman suggests that they were used as compound parts of knives rather than as projectiles.
Rock types seem to have played an important role in the form and function of segments at
Sibudu because segments form three populations based on rock types. The small quartz tools
might have been hafted transversely while larger, elongated hornfels and dolerite segments might
have been hafted diagonally or back-to-back. Rock types seem not to have influenced the forms
and functions of Umhlatuzana and Jubilee Shelter segments.
Jubilee segments (LSA) are as equally un-standardized as Sibudu and Umhlatuzana segments
(MSA). There is, however, some standardization amongst the length/breadth ratios of Howiesons
Poort quartz segments from Sibudu.
