Ficure 45.—Rim profiles and reconstructed vessel shapes of Mabaruma Incised, Mabaruma 
Phase (Appendix, table 13). 
Major vessel shapes reconstructed from sherds: 
1. Bowls with sidewalls varying from slightly incurving to outcurving, 
with the rim exteriorly thickened, creating a broad, flat top that 
slopes outward. The lip is tapered, producing a trianguloid cross 
section 1.2-1.9 em. in maximum thickness and 2.0-3.9 em. wide. 
Lobes are sometimes attached to the lip. Mouth diameter 26-32 
em. (fig. 45-1). 
2. Bowls with unthickened, sharply everted flange rims with a convex 
top that slopes strongly downward, rounded or tapered lip. The 
rim always forms an acute angle with the body wall usually from 
60-75 degrees. Width of flange rim ranges from 2.5-3.8 cm. with 
the majority around 3.0-3.5 em. Mouth diameter 22-34 em. (fig. 
45-2). 
DECORATION (pl. 29): 
Technique: Incisions made most typically with a round-ended tool producing 
a broad, U-shaped groove 1.0-1.5 cm. in depth and 1.5-3.0 mm. in width, 
with the majority 2.0 mm. wide. A few were made with a flat-ended 
stick. Thhe majority were incised when the surface was medium dry so 
there are no dragged particles of clay. About half of the sherds are care- 
fully incised ; the remainder showing careless or sloppy workmanship, with 
lines poorly spaced and crooked. 
Motif: Decoration is limited to the broad upper rim surface and consists of 
one to three incised lines parallel to the circumference. Two parallel 
lines are most typical. At intervals, small lobes break the continuity of 
one or more of the incisions. These lobes are 1.5-6.5 cm. long and affixed 
to the outer edge of the rim so that they protrude upward and. outward 
from 2-5 mm. (pl. 29, a—-d, f-i). They appear to be evenly spaced so 
they divide the rim into halves or quarters. Incised lines, punctates, 
spirals, or perhaps even stylized faces with eyes and mouths may be 
seen in these lobes, and they are also bounded by a curved line. 
TEMPORAL DIFFERENCES WITHIN THE TYPE: Although the rim sample per level in 
the seriated sequence is small, there is a suggestion that Form 2 is absent in 
the latter part of the Mabaruma Phase (Appendix, table 13).
