Research published in the Proceedings of the National Academy of Sciences notes evidence of chocolate consumption at a Puebloan site in New Mexico.

Cylinder jars that are used to drink chocolate were found at Chaco Canyon in northwestern New Mexico. That indicate the ancestors of today's Pueblo tribes traded with their counterparts in Mexico and Central America, an archaeologist said.

Scientists previously believed chocolate was introduced to what is now the United States by Spanish conquistadors, who learned about it from tribes in Mexico and Central America.
