Ordovician
- 2nd largest mass extinction
- 85% casualty on all marine and land species
- 60% of Marine invertebrates died
- Causes: Gondwana move southwards resulting to extensive glaciation and Sea level Fall

(N. America and Eurasia)
- mountain building in western North America
- following the Late Devonian Antler orogeny
- named by Silberling and Roberts
Sonoma Orogeny
- Marine genera observed extinction: 53%
- Calculated marine species extinct: 80%
- Extinction of Conodonts
- No clear cause has been found
Triassic-Jurassic Mass Extinction
Largest Mass Extinction
- Elimination of over 95% of marine and 70% of terrestrial species.
- Extinction of Trilobites, eurypterids, acanthodians, blastoids
Permian-Triassic Mass Extinction
Period of Siberian Traps
Permian
Enormous ocean surrounding Pangea
Panthalassa
Cause of the Great Dying
Cause:
- Bolide impact events
- Increased Volcanism
- Sudden release of methane from seafloor
- Sea level change
- Increase anoxia
- increasing aridity
- 5th largest mass extinction
- 80% of all living species , primarily the marine community have been wiped out.
- Extinction of cooksonia, tribulate corals, stromatoporoids, ostracoderms, and placoderm

La Garita Caldera
- San Andreas Fault
- Circum Pacific belt
- Early Antarctic Glaciation
