VESSEL SCALE 
Ficure 94.—Rim and base profiles and reconstructed vessel shapes of Mawika Plain, 
Taruma Phase. 
Major vessel shapes reconstructed from sherds: 
1. Griddles with irregular bottom, smooth upper surface, and upturned 
or slightly thickened rim. Diameter 30-60 cm. (fig. 94-1). 
2. Deep bowls with upslanting to nearly vertical walls, direct rim, 
rounded to flattened lip. Rim diameter 12-38 cm.; majority 28-38 
cm. (fig. 94-2). 
3. Rounded jars with constricted neck and slightly everted rim with 
rounded to flattened lip. Rim diameter 20-36 cm. (fig. 94-3). 
4, Rounded jars, walls incurving to direct rim and rounded lip. Rim 
diameter 20-26 em. (fig. 94-4). 
TEMPORAL DIFFERENCES WITHIN THE TYPE: Sample too small for determination. 
CHRONOLOGICAL POSITION OF THE TYPE: Present evidence suggests that Mawika 
Plain is absent from the earliest part of the Taruma Phase. Thereafter, it 
appears in small frequencies at scattered sites, reaching a popularity of more 
than 10 percent only at H-10, near the middle of the sequence (fig. 101). 
ONORO STAMPED 
PASTE AND SURFACE: Predominantly on Yoché Plain paste, with a few on Kalunye 
Plain; see those types for details. All features are typical, except that this 
decoration is not found on the extreme form of coarse-tempered paste found 
in Yoch6é Plain. 
Form: 
Rim: Everted with pointed lip; rarely, direct or thickened with flattened 
or rounded lip. 
Body wall thickness: 3.5-7.0 mm. ; increasing to 5.0-7.5 mm. at the decorated 
band.
