Is there, for example, a winged beast with cloven hooves and the head of a goat stalking the New Jersey Pine Barrens? The answer is almost certainly "no."
Reported sightings of this so-called "Jersey Devil" go way back. It's said that Joseph Bonaparte, Napoleon's brother, encountered the thing sometime in the 19th century. Yet no corpse or live specimen has ever been documented by the scientific community.
Take it from skeptic Michael Shermer, who wrote the following breakdown in his foreword to "Abominable Science: Origins of the Yeti, Nessie and Other Famous Cryptids" by Daniel Loxton and Donald R. Prothero:
