Most of the early Maya writing comes from between A. The earliest single Mayan glyph — which could have stood for a person's name or might have been a sign on a calendar — dates to about 600 B. "This is a full-blown and fully developed script," Saturno told Live Science.
"Which is not to say that the Maya invented writing and not the Zapotec, but it does lead us to question the origins and the complexities of these origins." One thing seems certain: The Mayan style was not influenced by the Zapotecs.
"The results indicate the existence of two pyramids inside the main Mayan building," said coordinating researcher René Chávez, a geophysicist at the National Autonomous University of Mexico.
Chávez added that although Mexican researchers discovered one of the interior pyramids in the 1930s, "the second substructure was just a hypothesis in some archaeologists’ minds." The new discoveries will be detailed in a poster presentation Dec.
That Chichen Itza was a thriving trade centre with a port at Isla Cerritos is evidenced by finds of goods from elsewhere in Central America, for example, turquoise from the north, gold disks from the south, and obsidian from the Isthmus of Tehuantepec. Argote said that although the dating of the structures is not fully proven, the pyramid's interior structure could add to the establishedchronology and understanding of the Mayan culture's early stages. [Photos: First Glimpse into a Mayan Tomb] There has been some controversy surrounding the chronology of Chichén Itzá, according to Denisse Argote, an archaeologist and geophysicist at Mexico’s National Institute of Anthropology and History.The Long Count is really a mixed base-20/base-18 representation of a number, representing the number of days since the start of the Mayan era. The basic unit is the kin (day), which is the last component of the Long Count.Going from right to left the remaining components are: Logically, the first date in the Long Count should be 0.0.0.0.0, but as the baktun (the first component) are numbered from 1 to 13 rather than 0 to 12, this first date is actually written 184.108.40.206.0.
