Trade Sherds 



Several sites of the Jambeli Phase produced sherds of plain or 

 decorated types belonging to two other cultures found in the Province 

 of Guayas. The largest number are of Guangala Phase origin; a few 

 represent the early Manteno Phase. 



Guangala Phase Types. — Sherds of Guangala Phase origin 

 include plain types and the following decorated types (Appendix 

 Table 2): Barcelona Painted Dark Line (Barcelona Linea Oscura), 

 Guangala Burnished Line (Guangala Brunido), Guangala Finger 

 Painted (Guangala Pintado con Dedo) and Chorrera Iridescent 

 (Chorrera Iridiscente). Although Guangala pottery was identified 

 at only a few sites, its seriated position (fig. 38) suggests that con- 

 tact between the Jambeli and Guangala Phases occurred throughout 

 the duration of the Jambeli Phase as it is now known. 



Mantei?o Phase Types. — A few plain sherds from Site G-L-30 

 were identified by Estrada as representing the fine kaolinite paste 

 of Play as Gray Polished (Play as Gris Pulido). Two decorated 

 sherds from Site 0-3 are Playas Engi-aved (Playas Grabado) (Estrada, 

 1957 a, p. 72). These types are characteristic of the Manteno 

 culture, which is later than the Regional Developmental Period, 

 Since these sherds are from surface collections, they are most easily
