The original Libby paper on carbon 14 dating in in this book.There was a "Hoax" mentioned that I had never heard of in California in 1886.R. A. Dart's paper on the South African/ Taungs discovery is nearly unreadable for his use of terms and language.For me some of the sedimentation diagrams were very good.I enjoyed this book which showed how hard it isto get a paradigm shift in Science.
