Unformatted text preview: 1 1 GEL107: PALEOBIOLOGY Lecture 3: Biostratigraphy & timescale 2 Sue the Tyrannosaurus rex at the Field Museum in Chicago is 65 million years old. Help me! I cannot imagine such a long time period. How do we know it? 3 How long is the geologic time scale? What is relative age and how do we use it to tell how old a fossil organism is?
