The occupation of Group D dates as far back as the Middle Preclassic period. Group D was occupied as late as the Terminal Classic, when a termination ritual was apparently performed, after which the northern building of the group was abandoned. The ritual included scattering a large amount of rubbish in front of the south entrance to the building and then possibly burning the building itself. The rubbish is presumed to have come from the area of Group D itself and included some items associated with weaving and the manufacture of paper.
