In this region we can through another method to deduce the ages more accurate, that is analysis the roof beams of these houses. Dr. Douglas in the University of Arizona invented a method of through analyzing the annual rings of the house roof beams to confirm the exact age of the beam. This way not only has fixed on the time frame of the Mayan’s settlement on calendar, but also has determined the corresponding ages of different potteries in the time scope. Compared to the United States Pueblo region, the sediment layers in the Maya region of pottery production were distributed more widely.

In addition to ceramic relic piles, in the ground of squares and buildings as well as tombs left by those upper ranks we also had found the sediment layer of ceramic flakes. All these sediment layers had been found in the Wuwaxiake, these sediment layers described a chronology for the main types of Maya’s pottery.

This chronology has provided us with a basic framework of the Peten region, and the age orders about Kepan will be published too, and other materials come from regions of Pidelasi, Nicholas, Palenque also had been dig out and been arranged well, and a book written about potteries dig out from Yucatan are just on printing process.

And the order of pottery from Zacualpa and Zaculeu are same, on the high ground of Guatemala, and the pottery orders of the formative years of Kaminaljuyu and former classical period were been recorded same.

Viewed from the marked changes of the pottery production in these regions, for the development of the whole Maya’s pottery, a large number of excavations in other areas are very essential, and due to the widely comparability between different areas, and timely amendment in individual areas based on the Maya chronology, all these have shown us with an overall chart of the Maya development.

Through the Maya monument that marked with dates, one day we would finally get an accurate dating standard. The accurate years of many Maya monuments were determined strictly in accordance with the Maya chronology, whose existence are merely used to make the Maya chronology corresponded to the Gregorian calendar, just as we could conclude the accurate age of a tree according to its tree-ring.

The above-mentioned we said are related to the at the types, the complexity, the quantity and specialization of Maya pottery, while they are so agree with the monuments that marked with accurate dates, so that when all the story fragments and all evidences came together, compared with the pottery production industry in other nations of ancient America, and from the pictures of Maya we may get more about the Maya’s pottery production, the origin places and sites of different types of Maya pottery, the industry distribution of Maya pottery and its final decline.
