JAMBELf CULTURE — ESTRADA, MEGGERS, EVANS 525 



larger area. Dots are 3-7 mm. in diameter, with little variation on a single 

 design. Smaller dots are more circular than larger ones, which may be 

 slightly ovoid. Rarely, dots are black and surrounded by a black ring. 

 Separation is from 1-3 mm. Unpainted stripes range from 2-8 mm. in 

 width; black stripes from 1-9 mm. Lines are straight or curved, and parallel 

 lines are commonly employed. 



Temporal Differences Within the Type: None discernible. 



Chronological Position of the Type: Present in minor frequency throughout 

 the seriated sequence (see fig. 38). 



Jambeli Plain (Jambeli Ordinario) 



Size of Sample: 6488 sherds. 



Paste: 



Temper: Abundant coarse white quartz sand with abundant pinpoint flecks of 

 mica. Quartz grains 1-2 mm. frequent, some up to 5 mm., and well dis- 

 tributed in paste. 



Texture: Sandy, giving abrasive feeling to eroded surfaces; compact; not friable. 

 Tendency to show lamination parallel to surface. 



Color: Typically, completely oxidized so that the cross section has the same 

 color as the surface. Thick rim may have medium to dark gray core. 



Method of manufacture: Coiling; sometimes fractured along coil junctions. 



Surface: 



Color: Rather uniformly orange to orange-tan or orange-brown; occasional 



medium gray fire clouds. 

 Treatment: Smoothing varies with vessel shape. Bowl interiors relatively even, 



showing fine brush marks adjacent to the rim, but never slick to touch; 



bowl exteriors typically swiped, leaving characteristic elongated marks from 



dragged temper grains parallel to rim. Jar necks have brushlike marks on 



interior and exterior; bodies poorly smoothed leaving uneven and irregular 



pitted surfaces. 

 Hardness: 4-4.5 

 Form (total rims from seriated samples, 561) : 



Rim: Exteriorly thickened, everted, interiorly thickened, expanded or direct, 



with rounded, flattened, or tapered lip. 

 Body wall thickness: Range 0.4-1.2 cm.; majority 5-7 mm. 

 Base: 1) flattened; 2) annular, diameter 10-28 cm.; 3) hollow polypod; maxi- 

 mum diameter 4-5 cm.; 4) solid polypod, diameter 3 cm., length 7.5 cm. 

 Reconstructed common vessel shapes: 



Form 9 — 46 percent 



Form 4 — 19.7 percent 



Form 11 — 14.8 percent. 

 Minor vessel shapes (frequency less than 5 percent): Forms 1, 5, 10, 3, 2, 12, 



and 13. 

 Appendages: 



Rim lug: Trianguloid lobe projection extending horizontally outward 3 cm. 



at rim. Examples are from the surface of Sites 0-3 and 0-6 (fig. 23, e). 



Temporal Differences Within the Type: None discernible. 



Chronological Position of the Type: Increases from a frequency of 3.6 percent 



at the earliest site to become the dominant plain type in the latter part of the 



seriated sequence (see fig. 38).
