Abstract
Mass extinction of reptiles including dinosaurs has been described by many paleontologists. The geologically-described age is at the end of the Mesozoic era and at the beginning of Cenozoic era. Dr. Dale A. Russell reports that at the end of the Mesozoic era, 15 separate families of dinosaurs, representing perhaps 50 to 70 distinct species, became extinct. He reports that not one dinosaur fossilized skeleton has been found in the geological column after the Mesozoic era and end of the Cretaceous period. Table I, taken from "Time Upside Down" by Dr. Erick A. von Fange, describes the classic or conventional geologic clock. We see the time described as occurring about 65 million years ago by classical geology.
