According to Shoshone tales, the Nimerigar were an aggressive people who would shoot poisoned arrows from tiny bows. Nimerigar were said to have lived in the Wind River and Pedro ranges of Wyoming. Although thought to be mythical, the reality of Nimerigar tales was called into question in 1932 with the discovery of the San Pedro Mountains Mummy, a 14-inch-tall mummy found in a cave 60 miles south of Casper, Wyoming, which was originally thought to be that of an adult male. The mummy was examined using X-rays which determined that it was the body of an anencephalic infant "whose cranial deformity gave it the appearance of a miniature adult." A second mummy examined by University of Wyoming anthropologist George Gill and the Denver Children's Hospital in the 1990s was also shown to be an anencephalic infant. DNA testing showed it to be Native American and radiocarbon dating dated it to about 1700.
