Nebraska Man was a name applied to Hesperopithecus haroldcookii, a putative species of ape. It was heralded as the first higher primate of North America. It was originally described by Henry Fairfield Osborn in 1922, on the basis of a tooth found by rancher and geologist Harold Cook in Nebraska in 1917.
Although Nebraska man was not a deliberate hoax, the original classification proved to be a mistake, and was retracted in 1927.
This illustration of H. haroldcookii, by artist Amédée Forestier, was modeled on the Java Man.
