Hallucigenia likely went extinct around 500 Ma primarily due to what process during the Cambrian Explosion?

• Global glaciation that froze shallow seas

• Ecological displacement as new, complex arthropods and predators evolved

• Massive volcanic eruptions leading to anoxia

• Asteroid impact causing rapid climate change

What is the most likely explanation for the extinction of Anomalocaris around 499 Ma?

• Global volcanic winter during the Permian

• Rapid terrestrial plant evolution

• Changing climate and sea-level drops or competition from later marine predators

What is the most likely reason the Orthoceras group largely died out near the end of the Triassic (around 200 Ma)?

• Global cooling that froze shallow seas

• Competition from more agile fish and marine reptiles that evolved later

• A sudden increase in volcanic activity

• Loss of planktonic food sources
