There is an apparent absence of settlements dating to the Late Ramos (200 B.C.-200 A.D.) in the major part of the area surveyed (only 15 sites, 170 ha comparing to 62 sites and 700 ha of Early Ramos). It is a striking fact because in Yucuita and Huamelulpan this period was a time of the major centralization and florescence of the regional states and general growth of the population. At the same time only two sites in the surveyed area had continuous occupation from Early Ramos to Early Flores while 20 had a gap between these phases.
