“…The results seemed to indicate conclusively that while ceramic types were shared across this vast region, it was entirely the result of shared ideals of ceramic style rather than exchange. According to that study, the major red, orange, and black-brown monochrome types were all being produced locally within each site or subregion of SE Mesoamerica (Bishop, Demarest, and Sharer 1989 Guatemala (Estrada Belli 1999Kosakowsky 1996, 1998;Estrada Belli, Kosakowsky, and Wolf 1998 (Wetherington 1978) and Xata Black-Brown at Bilbao (Parsons 1969 Red as identified at the highland site of Kaminaljuyu (Wetherington 1978;Demarest and Sharer 1986), Santa Tecla Red found at the sites of Chalchuapa (Sharer 1978) and Santa Leticia (Demarest 1986) (Wetherington 1978), and Rio Santiago Usulutain identified at Bilbao (Parsons 1969) on the Pacific coast of Escuintla (Bove 1989a(Bove , 1989b(Bove , 1993, and at the sites of El Balsamo and Monte Alto (Shook and Hatch 1978). In fact, Previous research by Neff et al (1994) speculated that the Late Preclassic Fine Reds found throughout highland Guatemala, El Salvador, and the Pacific coast might have been produced somewhere along the coast, east of Escuintla, because neutron activation analyses divided the Fine Red samples into two groups; one centered on the coastal plain of Escuintla, and the other on the highland site of Kaminaljuyu (Neff, Bishop, and Arnold 1988;Neff, Bishop, and Bove 1989).…”
