Pliocene sculptures or freaks of nature?

Stone that looks like a human head We have at hand Number 20 of Archaeologische Berichten, 1990, 108 pp. This thick booklet bears the subtitle Picture Book of the Stone Age. And a picture book it is, with hundreds of drawings interspersed with 26 pasted-in color photos. The text is English.

What do these photos and drawings show? Basically, they portray stones and pepples picked out of gravel pits and similar accumulations of rocky debris that look like human heads, ape heads, primitive tools, etc. Some of the pebbles do indeed resemble humanmade artifacts. (See accompanying sketch.) Most, though, require some imagination. The import of these artifacts, if that is what they really are, comes home when one learns that they come from deposits that are millions of years old! If any of these pebbles are really human-made, anthropology will be stood on its head.

Since the present report is the 20th in a series, one can assume that the contributors to Archaeologische Berich ten have amassed incredibly large collections of ancient stones and pebbles that "look like" artifacts.

Comment. Similar purported artifacts have been found at the controversial Calico Hills site, California, in Pleistocene deposits that may be 100,000 years old. And don't forget that "Face on Mars"!

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
