Big 5 mass extinctions

End-Ordovician; Late Devonian; End-Permian; End-Triassic; End-Cretaceous (K-Pg)

What were the major transgressions (epeiric seas) in Earth’s history?

Sauk Sea – Cambrian flooding that covered most of North America.

Tippecanoe Sea – Ordovician flooding, rich in shelly carbonates.

Kaskaskia Sea – Mississippian sea known for reefs and carbonates.

Absaroka Sea – Pennsylvanian; created coal beds and cyclothems.

Zuni Sea – Cretaceous transgression tied to superplume activity.

Name the transgressive sequence that is characterized by major carbonate deposits

Kaskaskia

Name the transgressive sequence that includes the Western Interior Seaway

Zuni

Name the transgressive sequence that includes the Transcontinental Arch

Sauk

Name the transgressive sequence that includes cyclothems

Absaroka

Name the mass extinction(s) that involved non-avian dinosaurs

K-Pg

Name the mass extinction(s) that was the most devastating in Earth’s history

Permo-Triassic

Name the mass extinction(s) that was/were caused by global cooling

Ordovician, Devonian

Name the mass extinction(s) that was/were caused by global warming

Permo-Triassic, K-Pg, Triassic

Name the orogeny(ies) that built the Appalachian Mountains

Taconic, Acadian, Alleghenian (Appalachian)

Name the orogeny that is characterized by a shallow subduction angle and a magmatic null

Laramide

Name the orogeny that is characterized by thin-skinned thrust faults

Sevier

Name the geologic period that the first mammal evolved

Triassic

Name the geologic period that is described as the age of fishes

Devonian

Name the geologic period that includes the Burgess Shale

Cambrian

Describe evidence and significance of the first land plants

Microbiotic crust stabilized crust. Wind erosion not as important.

Describe evidence and significance of the first tetrapods

Amphibians, many adaptations out of the water.

Describe evidence and significance of the Paleocene-Eocene Thermal Maximum

Mammals shrunk, coral bleaching, hot house Earth, foramen dying.
