U.S. and Honduran archaeologists have begun excavations at a mysterious site on Honduras' Caribbean coast that may be the near-mythical "White City" ruins.

Officials said Friday that excavation began Wednesday at the site, and have so far unearthed about five dozen ceramic fragments.

Also known as the "City of the Monkey God," the site is located in Honduras' jungle-covered Mosquito coastal region.

The dig is being carried out by archaeologists from Honduras' Institute of Anthropology and Colorado State University.

Institute Director Virgilio Paredes said the site did not appear to be Mayan, the culture that dominated other sites in the region.

Paredes said "it is a new culture, or a different culture."
