After exploring a subterranean cavern, an archeologist found more than 100 black and red handprints on the walls of the ancient Mayan cave in Mexico's Yucatan peninsula.
The 137 prints, mostly made by children's hands, are believed to be associated with a coming-of-age ritual of the ancient Maya and have been determined by archaeologists to be more than 1,200 years old.
According to Mexico Daily News, archeologist Sergio Grosjean found the handprints in a cave close to the northern tip of the Yucatan peninsula.
The date of the handprints corresponded near the end of the ancient Maya's classical zenith, when humans were achieving major advances in art and math.
