Belief in this deity started among the Meso-Americans of Guatemala which was described as a dangerous cave-dwelling bat creature known as Camazotz. In the Maya culture it is linked to death. and inhabits a cave called the "house of bats" in the Popol Vuh.
This monster bat would attack victims and decapitate them. Camazotz is identified as one of the four animal demons.
Another version of bat-like monsters in Peru and Chile is called Chonchon. It was supposed to have been created by a sorcerer or "kaku" who through dark magic caused a severed head to sprout giant ears that became wings and talons.
Some archaeologists suggest that the basis for these stories are encounters with real vampire bats. This animal has a historical connection to bloodletting and sacrifice.
There was a giant bat that existed during the Pleistocene age that was about 25% larger than modern vampire bats. Its name is Desmodus Draculae or giant vampire bat. In a 1988 a fossil of this bat was discovered in the Mongas province of Venezuela. Additional evidence have been found in the Yucatan peninsula, Belize, northern Brazil and Argentina. It is not known when Desmodus Draculae went extinct, if at all.
The latest age for fossils found for this giant bat have been dated to approximately 1650 AD, which leads to the belief that it coexisted with human beings in Central and South America.
Recent sightings date back to 1947, when J. Harrison claimed to have seen large creatures he described as giant bats with wingspans of about 12 feet.
In the early 1950s a Brazilian couple claimed to see a giant bat as they walked in a forest of Pelotas, in the same area that fossils had been recovered. The couple however described the creatures as being humanoid in appearance.
In the mid-1970s, different witnesses claimed to have seen a creature described as a bald bat or pterosaur-like with a short beak and gorilla-like face. Three-toed prints were said to have been found at the place of one of the sightings.
In 1975, there was an outbreak of animal mutilations in the town of Moca in Puerto Rico. A farmer and others who lived in the area of the attacks described seeing two grey, bird-like creatures.
Fossil evidence, strange stories and native mythos points to the possibility that man and giant vampire bats crossed paths many times. Were humans ever victims for an animal that lived from ingesting blood?
The Zapotec was a pre-Columbian civilization that flourished in the Valley of Oaxaca in southern Mexico. They built the ancient city of Monte Albán. The Zapotec practiced human sacrifice and bloodletting rituals. Examples of the bat god have been found by archaeologists.
Mayans of Central America believed the bat was the guardian of the underworld and a powerful force against enemies.
