Bill Nye the Science Guy (1993)

Episode Overview

Explore the fascinating world of dinosaurs through the lens of fossils, the only remnants of these incredible creatures. Dinosaurs, which roamed the Earth 65 million years ago, left no newspapers or family photos behind. Their existence is solely documented by fossils, particularly bones, which would have disintegrated if not for specific circumstances. When dinosaurs perished, their remains were often buried in mud or sand, protecting them from the elements. Over millions of years, these bones absorbed minerals, preserving their structure. While we can't witness their extinction, many scientists believe it was due to meteorite impacts that created massive craters and unleashed dust into the atmosphere.
