A stela dated to AD 780 records a ceremony performed by king Aj Yaxjal B’aak and attended by his overlord from the Petexbatún, most likely to have been Tan Te' K'inich of Aguateca, and 28 other lords from both within the Dolores valley and further afield. Ixtutz experienced a decrease in activity during the Terminal Classic period, after AD 825 all sites in the region ceased to erect further monuments although occupation continued. Ixtutz and other centres in the Dolores region were finally abandoned at the end of the Terminal Classic.
