文本解說

在墨西哥塔巴斯科州的阿瓜达费尼什的土路和大量植被下，科学家发现了一个占地约56万平方米的玛雅遗迹，这是迄今为止发现的最大、最古老的玛雅文明建筑。

Scientists have discovered the largest and oldest known structure that was built by the ancient Mayan people.

Large and shaped like a rectangle， 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 Egypts 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 a laser and other information collected by flying over an area to create three dimensional information about a surfaces 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 as jade axes.
