RealClearScience has a series of pix entitled "These Animals Are Fake, We Wish They Weren't." I'm disappointed they totally omitted Wyoming's jackalope, a jack rabbit sprouting antelope (pronghorn) horns.
A jackalope is the supposed result of an amorous buck jack rabbit taking a fling at an antelope doe. Taxidermy examples of jackalope decorate many Wyoming bars and guest lodges. It's a poor jack rabbit's best shot at any sort of immortality.
As opposed to the mythic jackalope, Wyoming's antelopes, technically "pronghorns," are very real, beautiful animals and the fastest land creatures in North America. Scientific name Antilocapra americana, pronghorns are hunted and the flesh is edible, but not as tasty as elk.
Wyoming hunters call them "goats" because a dressed out pronghorn carcass looks like a dressed out goat carcass. A mounted male pronghorn head makes an attractive addition to a hunter's "head wall."
Postscript: Oops, if you click on the link labeled "For even more, go to the Museum of Hoaxes' Tall Tale Creature archive." and scroll down you'll find the jackalope. I am relieved. Hat tip to the other DrC for spotting the buried link.
