An enormous pyramid-topped platform, unnoticed until detected with the help of lasers, is the oldest and largest structure in the Maya region.
An enormous 3,000-year-old earthen platform topped with a series of structures, including a 13-foot-high pyramid, has been identified as the oldest and largest monumental construction discovered in the Maya region, according to a paper published today in the journal Nature.
It’s the latest discovery to support the emerging view that some of the earliest structures built in the Maya region were significantly larger than those built more than a millennium later during the Classic Maya period (250-900 A.D.), when the empire was at its peak.
The discovery took place in Mexico’s Tabasco State at the site of Aguada Fénix, about 850 miles east of Mexico City. It is in a region known as the Maya lowlands, from which the Maya civilization began to emerge.
In 2017, researchers conducted a LiDAR survey that detected the platform and at least nine causeways leading up to it. The groundbreaking laser technology typically is used from aircraft to “see” structures beneath dense tree canopy below, but in this case it revealed a stunning discovery sitting unnoticed in plain sight in Tabasco’s semi-forested ranch lands for centuries, if not millennia.
So why was such a big monument at Aguada Fénix not identified earlier?
“It’s fairly hard to explain, but when you walk on the site, you don’t quite realize the enormity of the structure,” says archaeologist Takeshi Inomata of the University of Arizona, the lead author of the paper. “It’s over 30 feet high, but the horizontal dimensions are so large that you don’t realize the height.”
“Rituals we can only imagine”
The initial construction of the platform is believed to have began around 1,000 B.C. based on radiocarbon dating of charcoal inside the complex.
But the absence of any known earlier buildings at Aguada Fénix suggests that at least up until that period, the people living in the region—likely the precursors of the Classic Maya—moved between temporary camps to hunt and gather food. That has researchers speculating over how and why they suddenly decided to build such a massive, permanent structure.
