Bill Bryson Chapter 14 The Fire Below - Josh Ogier

In 1971, Mike Voorhies discovered one of the most extraordinary fossil beds in North America. It was a mass grave for scores of rhinos, horses, saber-tooth deer, camels and turtles killed around 12 million years ago. They were killed from breathing abrasive ash spewed by a volcano. Scientists say that they know more about outer space than the core of the earth. In around 1938 Charles richter and Beno Gutenberg created the Richter scale. The Richter scale is often mistaken as a machine when it is actually more of an idea. In the 1960s in an attempt to get a better understanding of the core they tried to drill into the core which was disastrous. Scientists are in a dispute about how the crust was created, some believe it happened fast early in earth's history while others believe it happened slowly over time.
