woe" ARCHEOLOGY IN BRITISH GUIANA 309 
4, Wiat, circular griddles with slightly thickened or upturned edges. 
Interior relatively even, exterior typically poorly smoothed. Rim 
diameter 34-68 cm. (fig. 122-4; pl. 67). 
5. Globular jars or bowls with everted rim and rounded lip. Rim 
diameter 16-50 cm. ; majority 22-86 cm. (fig. 122-5). 
6. Jars with rounded body and constricted neck, vertical or slightly 
everted rim. Rim diameter 7-14 cm. (fig. 122-6). 
Appendages: 
Handles: Vertical strap handles have an oval cross section 24 cm. 
wide (fig. 122; pl. 68, 7). Only one is attached to a rim sherd and 
this is a vertical-sided bowl of Form 1. Fragments are rare, one 
each recorded from R--26, R-27, R-82 and R-86 A, and two from 
R-6. 
Applique: A horizontal rim lug attached to the rim of a shallow bowl 
comes from R-82. The lug is 5 em. long, projecting 2.5 em., with a 
nicked outer edge. A similar lug probably was attached to the 
opposite side of the rim. 
Conical nubbins 2-38 cm. in diameter and 1.5-2.5 em. high occur 
in pairs at four places around the circumference above the shoulder 
on burial vessels of Form 8 (pl. 65, 6) and on opposite sides below or 
on the rim of Form 2 (pl. 68, e-f). These are not firmly attached 
and readily slough off. 
OccCASIONAL DECORATION: Rarely, incisions (pl. 63, j) or fingertip punctations 
(pl. 68, 7, &) appear on the lips of vessels. 
TEMPORAL DIFFERENCES WITHIN THE TYPE: Pedestal (Form B) and rounded 
(Form C) bases appear to be most frequent in the early half of the sequence, 
although this may be a reflection of the small size of samples from later 
sites. Vessel Shapes 3 and 5 are slightly more characteristic in the latter 
half of the sequence, while Vessel Shape 2 tends to be more frequent in the 
earlier sites (Appendix, table 38). 
CHRONOLOGICAL POSITION OF THE TYPE: Kanuku Plain is the dominant pottery 
type at the beginning of the seriated sequence, representing 88.4 percent of 
the total pottery at the earliest site. It shows a steady decline in popularity 
to 20.8 percent at the latest site (fig. 125). 
RUPUNUNI PLAIN 
PASTE: 
Method of manufacture: Coiling; sherds with one edge broken on a coil 
line are frequent and a number show coil line breaks on two edges, one 
concave and the other convex (pl. 63, m—-p). Single coils range from 
1.0-2.5 em. wide. Some base sherds have an impression on the exterior 
of a simple twilled mat on which the vessel rested during manufacture 
(pl. 67, e). : 
Temper: 
Coarse granitic sand, typically readily visible and abundant, with grains 
protruding on eroded surfaces. Mica flecks are sometimes present, 
and appear to reflect the local sand composition. Temper grains are 
typically under 3 mm. in diameter, with occasional larger hunks. 
Occasional sherds from. 7 sites also contained black ash, the particles 
ranging from pinpoint size specks to hunks 5-8 mm. long and 0.5-1.0 
mm. wide. Quantity varies from sparse to abundant. In most cases 
all sherds from a site appear to belong to a single vessel. Sites that 
produced these sherds are: R-3, R-5, R-20, Cave 2, R-20, Cave 38, 
. R-22, R-36, and R-37.
