Among the many well-preserved details are a sculpture of an owl that sits above the entrance to the burial chamber. A sculpture of a man’s head can be seen inside its beak, possibly representing the individual who was buried inside, according to the INAH. Hundreds of thousands of Zapotec speakers still live in Mexico to this day. At the threshold to the burial chamber there are carvings of two human figures holding various artifacts in their hands, who may have been the guardians of the tomb, according to the INAH. “It’s the most significant archaeological discovery of the last decade in Mexico due to the level of preservation and the information it provides,” she said.
