The Archaeology of Chichén Itzá suggests that its construction fundamentally date of the period Classic Terminal or Epiclassic (700-950 AD), instead of the Post-Classic Periodo (950-1100 AD). This draws attention to the implications of chronology for the well known problem tolteca. We are working with the assumption that the occupation of Chichén Itzá is, in the most part, prior to the stage Tollán of Tula (900-1200 AD), which leads us to believe that what is usually identified as tolteca iconography and therefore uplands of origin of the center-Mexican, in fact date Epiclassic horizon.
