dinosaur extinction
Prehistoric reptile die-off
The dinosaur extinction refers to the mass die-off of non-avian dinosaurs approximately 66 million years ago, ending the Cretaceous period.
An asteroid impact and volcanic activity triggered catastrophic climate changes.
The phrase appears in discussions of evolution, paleontology, and existential risk: Could climate change cause a dinosaur extinction–level event?
Figuratively, it describes the sudden obsolescence of once-dominant entities: The streaming revolution was a dinosaur extinction for video rental stores.
