Charles Hapgood's rare book, Mystery in Acambaro, is back in print! Hapgood researched the Acambaro collection of clay figurines with Erle Stanley Gardner (author of the Perry Mason mysteries) in the mid-1960s. The Acambaro collection comprises hundreds of clay figurines that are apparently thousands of years old; however, they depict such bizarre animals and scenes that most archaeologists dismiss them as an elaborate hoax. The collection shows humans interacting with dinosaurs and various other "monsters" such as horned men. Both Hapgood and Gardner were convinced that the figurines from Acambaro were authentic ancient artifacts which indicated that men and dinosaurs had cohabited together in the recent past, and that dinosaurs had not become extinct many millions of years ago as is commonly thought. David Hatcher Childress writes a lengthy introduction concerning Acambaro, the latest testing and other evidence of "living" dinosaurs.
