The giant mask found at the sit of Ucanha has been dated to the 4th century CE. INAH said the mask was found in 2017 and protected from looters then by not announcing the discovery.
Jacob Welch, a graduate student at Yale University found the mask along with a team made up of Mexican and American researchers, laborers and other students.
Excavation of the mask began in 2019.
Inah has reared the mask which portrays a ruler or deity with a large, protruding nose and an elongated head. Intricately carved symbols flank the face on both sides.
