Nebraska Man

This illustration of H. haroldcookii, by artist Amédée Forestier, was modeled on the Java Man.

Nebraska Man was a name applied to Hesperopithecus haroldcookii, a putative species of ape. Hesperopithecus meant "ape of the western world," and it was heralded as the first higher primate of North America. Although it was not a deliberate hoax, the original classification proved to be a mistake.

History

It was originally described by Henry Fairfield Osborn in 1922, on the basis of a tooth that rancher and geologist Harold Cook found in Nebraska in 1917. An illustration of H. haroldcookii was done by artist Amédée Forestier, who modeled the drawing on the proportions of "Pithecanthropus" (now Homo erectus), the "Java ape-man," for the Illustrated London News. Osborn was not impressed with the illustration, calling it: "a figment of the imagination of no scientific value, and undoubtedly inaccurate."

Restoration of what Prosthennops may have looked like in life

Further field work on the site in 1925 revealed that the tooth was incorrectly identified. Other parts of the skeleton were also found. According to these discovered pieces, the tooth belonged neither to a man nor an ape, but to a fossil of an extinct genus of peccary called Prosthennops, and its identification as an ape was retracted in the journal Science in 1927.^[1]

Although the identity of H. haroldcookii did not achieve general acceptance in the scientific community,^[2] and the purported species was retracted half a decade after it was proposed by Cook, creationists have promoted the episode as an example of the scientific errors that can undermine the credibility of paleontology and hominid evolution theories, and how such information is peer reviewed or accepted as mainstream knowledge.^[3][4]
