Eolith
Eolit - a stone with irregular, worked edges, which, as a result of geological processes, has become a form reminiscent of the original stone tools of man. The first eolith discovered in 1885 Benjamin Harrison, amateur archeologist. Harrison's discovery was published in 1891 by British geologist Sir Joseph Prestwich, recognizing stones as crude, original tools from the Pliocene era. Further discoveries of the early 20th century in eastern England, as well as on the European continent, were taken as evidence of human existence in these areas even before the earliest known fossils. They were used as proof of the authenticity of the Piltdown Man skeleton. Because of the primitive, raw nature of stone processing, the theory of eoliths was developed as a result of natural geological processes such as glacier activity or erosion. In 1905 French archaeologist Marcellin Boule in L'Anthropologie denied that the eoliths were artifacts.
