Originated in 1939 by Douglas Herrick, the jackalope can be described a as a type of rabbit that features the horns of another animal, which is believed to be an antelope, goat or deer. The creature is mythological and part of folklore in the United States, particularly in Douglas, Wyoming, where novelties featuring the creature are sold. Some people even in the 21st century claim to have seen the creature in the U.S.
Although the jackalope is mythological, some scientists do think there may have been horned rabbits in the past. The creature gets its name from a combination of the words "antelope" and "jackrabbit," which describes a jackrabbit with horns like an antelope. Other cultures also have similar horned creatures in their mythologies.
