The Acambaro collection of Mexico 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 Earl Stanley Gardner were convinced that the figurines from Acambaro were authentic ancient artifacts that indicated that men and dinosaurs had cohabited in the recent past, and that dinosaurs had not become extinct many millions of years ago as commonly thought. David Hatcher Childress writes a lengthy introduction concerning Acambaro, the latest testing, and other evidence of living dinosaurs.
