How about Stuart Piggott's report (a British archaeologist) in "The Radio-Carbon Date from Durrington Walls", ANTIQUITY, xxxiii, No. 132, (Dec. 1959), page 289. Here he reports that two radiocarbon tests on a sample of charcoal indicated a date of 2620-2630 BC for an ancient structure at Durrington Walls in England. However, absolutely compelling archaeological evidences called for a date approximately 1000 years later. Another prominent archaeologist, Professor V. Milojcic, states that some radio carbon dates from south-eastern Europe are 1000 years too high -- see H.T. Waterbolk, "The 1959 Carbon-14 Symposium at Groningen," ANTIQUITY, xxxiv, No. 133, (Mar 1960), pages 14-18. Unless Carbon-14 dating techniques have changes dramatically since 1959 I would be inclined to be skeptical about any carbon-14 dates! The fact that it can be 1000 years off for something as recent as 1600 BC suggests to me that Carbon-14 dating is worthless, and any scientist who uses it cannot be taken seriously. If I'm not mistaken, it is rarely used anymore. However, the interesting thing is that many people are still clinging tightly to the data gathered back in the days when Carbon-14 dating was in vogue -- worthless data!
