Geologic Time & the Geologic Time Scale
How do we make sense out of a 1000 foot-thick rock sequence? Rock Units: Supergroup Group Formation Member Bed Time Units: Eon Era Period Epoch Stage
Geologic Time as a Linear Progression
Geologic Time in one Hour Hadean – Proterozoic eons Proterozoic & Phanerozoic eons
Evolution of Life on Earth (in 1 hour)
Earth’s Geologic Time in 100 Yards Phanerozoic Eon begins between 12 and 11 yard lines
Geologic Time as a Spiraling Line
2009 Geologic Time Scale Subdividing 4. 6 billion years into smaller, more “manageable” intervals
Phanerozoic Cenozoic Neogene Eocene Bartonian Time vs. Eon Era Period Epoch Age Time-rock Eonothem Erathem System Series Stage
Don’t mix time units with rock units! vs. Time Eocene Fossils Late vs. Rocks Upper Meaning: Late Eocene fossils are found in Upper Eocene rocks. So Periarchus lyelli (sand dollar) lived during the Priabonian age and fossils occur in rocks from the Priabonian stage.

2009 Cenozoic Era – goodbye Tertiary, hello Paleogene/Neogene 1980 s Subdivisions were based on fossil content…
If the type section for the Ordovician is in western England, how do we know rocks in Eastern USA are the same age?
