Scientists have discovered the largest and oldest-known structure that was built by the ancientMayanpeople.

Large and shaped like arectangle, the structure was built between 2,800 and 3,000 years ago in what is now the Mexican state of Tabasco. Unlike the large Mayan pyramids built some 1,500 years later, the newly discovered building was made with clay and earth. It was likely used for ceremonies, researchers said.Built near the Guatemalan border, the structure measured nearly 400 meters wide and nearly 1,400 meters long. It stood between 10 and 15 meters high. It had more volume—the amount of space—than Egypt's Great Pyramid of Giza.

Researchers noted that there were no signs of statues of powerful or wealthy people. This suggests Mayan culture may have had more equality during this period. Takeshi Inomata, an archaeologist at the University of Arizona, led the research. The findings were published in the scientific journal Nature.

Inomata said that because the structure is so large. “It just looks like a natural landscape,but its form comes out nicely in LiDAR,” he added. LiDAR is short for Light Detection and Ranging, a method for measuring distances. It uses alaserand other information collected by flying over an area to createthree-dimensionalinformation about a surface's shape. Some parts of the site are currently covered with cattle ranches. Other parts have trees.

But in ancient times, Inomata said, the structure was likely used for special events.People probably walked on raised paths and inside the rectangular structure. He said they left symbolic objects behind, such asjadeaxes.
