Summary:
- Dinosaur teeth can provide valuable information about the Earth's climate in the past. The chemical composition of the teeth reflects the environment the dinosaurs lived in.
- Researchers analyzed the teeth of plant-eating dinosaurs and found that they contained high levels of carbon dioxide, indicating the atmosphere had much more CO2 during the dinosaur era compared to today.
- This information helps scientists better understand how the Earth's climate has changed over millions of years and how high levels of CO2 can impact the planet's temperature and ecosystems.
