SUMMARY
The asteroid impact that caused the Cretaceous–Paleogene extinction event approximately 66 million years ago led to the extinction of the dinosaurs through a combination of immediate and long-term environmental changes. The impact created massive wildfires, released dust and debris into the atmosphere, and caused a significant drop in temperatures, disrupting ecosystems. This catastrophic event is widely supported by geological evidence, including the presence of iridium-rich layers in the Earth's crust, which is characteristic of extraterrestrial objects.
PREREQUISITES
- Understanding of the Cretaceous–Paleogene extinction event
- Familiarity with geological evidence and iridium layers

- Awareness of prehistoric ecosystems and dinosaur biology
NEXT STEPS
- Research the geological evidence supporting the asteroid impact theory
- Study the environmental changes during the Cretaceous–Paleogene transition
- Explore the role of wildfires in mass extinction events
- Investigate other theories of dinosaur extinction beyond the asteroid impact
USEFUL FOR
Students of paleontology, geologists, and anyone interested in the factors contributing to mass extinction events in Earth's history.
