Fig. 11 Flints from the causewayed enclosure L14—L25 
interior features have breadth:length ratios of less 
than 2:5, the most frequent ranges being 
respectively 3:5-4:5 and 2:5-3:5 (archive). 
Among complete chips, the most frequent 
diagnostic forms are core front chips, characterised 
by an elongated form, central ridge, small butt, 
feathered edges and straightish profile (Newcomer 
and Karlin 1987, 33-34). Their presence 
corresponds to the regular removal of overhang 
‘from core platforms by platform edge abrasion 
(Figure 10, L4). The near absence of faceting chips 
matches the rarity of platform faceting, which was 
recorded on 1% of the flakes in the samples (listed 
in archive). Retouch chips are scarce, correspon- 
ding to the low proportion of retouched forms. A 
few bulbar scar chips are present, translucently 
thin, with feather terminations and with bulbs of 
percussion on both faces. Complete chips are 
generally fan-shaped, broader than they are long 
and non-cortical. Most lack a complex sequence of 
dorsal scars and many end in hinge fractures. 
Retouched forms 
The composition and incidence of retouched 
forms are summarised in Table 4 and detailed in 
archive. Like the low frequency of blades, the low 
percentage of retouched forms, 0.7% overall (Table 
3), cannot be attributed solely to large-scale 
sieving, since retouched forms amount to only 
0.6% and 1.7% of the manually recovered material 
from the primary fill and recut of the causewayed 
enclosure ditch, proportions comparable with the 
0.7% from the interior features. If the small 
fraction is discounted, retouched forms. still 
account for only 1% of the material from these 
contexts.
