Geologists conclude:
1. Earth is ancient
2. Earth has changed A LOT through time
Scientists also started to suspect it was not just the landscape that had changed life
(the biosophere) had too!
- Ex: George Cuvier (1800s) - mammoth remains in Europe
- Concludes: Mammoths were ONCE LIVING species that have become extinct
- THE GEOLOGICAL TIME SCALE (learn this!)
- To allow all of this “change to happen” Earth had to be very old.
- Started to divide time into specific divisions based mostly on the different
tpes of fossils they contained
- Many of these divisions based on large extinction events
- Look at the Precambrian compare to Phanerozoic
