The name means Dawson’s down man after one of the discoverers, Charles Dawson.  This fossil skull was supposedly found in a gravel pit near Piltdown, England.  It was thought to be a remarkable fossil find until 1953 when it was discovered that the skull was human and the jaw was that of a modern Orangutan.  It was declared a hoax!  The dark areas of the skull indicate the original fossil material and the light areas represent the reconstructed material.
